CLIL unit for chemistry teachers (2).docx

In the italiann schools we are obliged to teach in a relative language that i sthe english ones. On the basys of this , all teachers re called to make the best to reach this purpose. Herein we want toexplain how to write a clil unit in particular for all chemistry teachers.

The CLIL Unit for Chemistry teacher To all my closest friends To all those who believed in me. Index Introduction pg 4 Writing a CLIL Unit for chemistry teachers pg 6 Contents of the CLIL for chemistry teachers pg 8 The preview in the chemistry: Carbon, hydrocarbon, Alcohols and amines pg 8 3.2 The carbon pg 9 3.3 Polymers pg 11 3.4 Addition and condensation polymerization pg 14 3.5 Hydrocarbons and derivatives pg. 17 3.6 Alcohols pg 19 3.7 Amines pg 22 Conclusions pg 25 Bibliografy and sitography pg 26 Introduction In each school context, in the respect of the actual Italian law, called the ‘’good School’’ and coming out from the consulting of all the Italian community, each school is obliged to consider different kind of pupils because each of them should reach the plenary success in the school. The school context remain the place to promote the development of strategic point of view for the people, it is the major place where a student build its own personality. Moreover the school must contribute to perform in in student an active citizens, who are aware about who they are, who are aware on what they had eventually to do to improve society where they are now leaving, and where it is necessary to close or to make a change for the new lives that are going to came into the light. Alumni in the Italian school must know what is civilization, what means living in a culture where all the individual rights are respected, be educated to the peace, loyalty, cooperation among people, against each form of racism and peace or kind of ancient totalitarism. The future citizen will be able to serve the State with honourability, with severe intransigence and indulgence; this the State claims from its citizenship.( the Italian Constitution, 1945). Education is important for its citizenship (art 32 of Italian constitution). It seem to respect the same thoughts and speechs of Malala.’’ I do not care where I have to sit down in my school. All that I want is education. I have no fear of anyone.!) Declaration on human right of children and teenegers. Education have to be for all, sure also for handicapped or inabled people, for whom their rights were recognized after years of fight. To make it possible schools and the people working inside makes a pact with their students. It permits that pupils can apprehend all the key competencies ( Petracca, 2015) imposed also by European Community, so that students can grow up with particular competencies (Pellerey, 2014). In particular all the different kind of pupils called BES, special educational needs, are to be included in the school ( Index for the inclusion , Boith, Ascow 2014) also to fight against the premature leaving school. Unfortunatly inclusion doesn’t mean to have a person inside the school living overthere in a complete state of isolation. It means that people must feel inside the school and he must have the possibility to understand how to learning, how to catch the learning object for the own future. The pact guarantee that education of all alumni have to be pursed on the basis of high quality criteria, that implies the continuum learning of all school body (teachers, principal, collaborator, staff etc.), named for year LLP program.(or today as Intercultura, Comenius, Erasmus +). In a way we have to remember the high social role of teacher in the school because they remain a reference for all those who are called to save life with a particular regards to the boss ( the principal) of the school who, is actually became also the manager of the public school. To this pact families and pupils are called and have to take part too: in particular students are at the centre of the school: considered ( like in the Umanesim period) to whom the educative action have to be direct according to the Piaget and Vigotsky’ s theories.( Mondelli , 2015). During each cycle and at the end of it teachers have to certifies competencies as the sum of knowledge and skills, because certification is a passport of what they have learned, of what they know or what they don’t know and have to improve. Teachers, indeed, are the scaffolders, the guides to enrich the formal, non formal and informal knowledge of the novel pupils also with the aim that each pupil can reach the total autonomy and responsibility, as one of the most important principle of Italian Constitution. The text ley 107 of 2015, changed POF into PTOF. Ptof explains what that kind of school offers in terms of teaching, organization, timetable, for a period of three years to all the alumni studying over there. On the proposal of teacher Advice, PTOF can be changed not compulsory at the end of the three years, with the introduction of other important modification or pills, that means adding new subject offers, new particular area of interest for alumni, new interesting and challenging projects, etc. This for sure is a great escamotage to attract people in the school. Thus, together with high teaching quality and good organization skills in the school, that mean good organizational skills of the principal, in the school is possible to attract new alumni so that the RAV is considered positively. In particular is considered positively the presence of foreigners in the schools. With the effect of the same law, the schools at the last year must teach the characterizing matter for the final exam in a language, that are English for scientific matter and French for the others. It means that teachers, during the school years must vehiculate contents of their matter to their pupils with that language, as it is required on the basis of the actual schools programs. This methodology goes under the name of CLIL, and it gives alumni the way to learn specific learning object of that matter, while they are talking in the ‘ CLIL’ language. Can we estimate how much is efficient this methodology? Can we understand if results in acquiring new terms of a matter in the vehiculate language is immediate? What are the problems connected to this approach for dislexys student, because of the high percentage of them in the school all around the world? When is better to use the CLIL methodology? According to the recent literature, we cannot estimate how long pupils need to acquire new words in their vocabulary, in expecially way when you are working with a different kind of persons, not only children or teenegers, but also adults that are psychologically more instable, for the high numbers of pathologies associated with the adult life. That is why perhaps on the basys of a Bloom theory, the ‘absorbent mind ‘ highly active in children and almost lost in the adult life, we can define differently the way of learning of adults, children and teeneagers: we are exepected to collect great new words for children, medium one for teenegers and a little amount for adults. Apart from rapidity to apprehend new words, we must consider the kind of word alumni have to learn. For sure, the teacher will start with more common terms in that language, then it will be possible to teach English for special purpose, for the difficoulty that is hidden in the matter. This is probably why children start to be familiar with chemistry world around the elementary schools. Then the effects will be more visible waiting for the right time and using facilitating terms to transmit what a person like to transmit in her matter and waiting for. Essentialism is one of the goal necessary for teachers and educators to reach a good result. Synthetic words, synthetic schemes, and synthetic concepts to be delivered make you, perhaps a better teacher.

Controls Correction of the activity in the classroom What is chemistry about? Chemistry is the study of the composition and of the properties of matter, and how this can undergoes changes. Chemistry is very old subject for the fact that it was known until the ancient time, but during it it was considered a pseudoscience, something of magic of the period and it was best known with the name of Alchemy. During that times people believed that chemists were able to transform lead and other metals into the precious gold. Today, instead, this old belief was overcame and now we now that chemistry can be divided into different divisions and can have different applications in our lives. So chemistry can be divided into organic chemistry and inorganic chemistry. Organic chemistry is the study of compounds of carbon, while inorganic chemistry is the study of the other chemical elements and related compounds. For someone chemistry is a ‘central science’ because it is a link with the other natural science such as physics, biology, astronomy, geology. As a matter of the fact all natural sciences, basic and applied Basic or pure science is concerned with the gathering of information solely for the sake of obtaining new scientific knowledge , while applied science is the practical application of scientific theories and laws., must refers to a certain extent to chemistry: plants, rocks, the atmosphere, medicines, the environment ( air, water, minerals and so on) cannot be deeply understood without the help of chemistry. At the same time chemistry has brought people new products and processes and common people use chemical products to their homes, like cleaners, medicines, cosmetics and so on. It can be said that chemistry is involved in a lot of aspect of everyday life. TRUE OF FALSE Say if the following sentence are true or false, the correct the false ones 1) Chemistry can be considered a recent science T F 2) Inorganic chemistry studies chemical elements and their compounds T F 3) Organic chemistry is based on carbon and carbon compounds T F 4) Matter undergoes changes that can be explained with the help of chemistry T F 5) Chemistry is called the central science because it studies the centre of the earth T F 6) Chemical products are commonly used in everyday life.

The experimental method The experimental , or scientific , method is fundamental for the study and the progress of science. This general method is used not only for chemistry, but also in biology, physics geology and other sciences. The experimental method can be described as a series of cycles , and each cycle is divided into seven steps. The first step consists in making objective observations, that is , observations that can be verified by other scientists. Starting from the observations and data obtained, in this second step scientists develop a general principle that is called hypothesis A hypothesys is a theory or supposition used to explain events or phenomena. It is provisionally accepted , waiting fot further investigations and observations tht can confirm or confutr the hypothesys itself. The hypothesys is not proven true , but only verified or corroborated by facts.. A hypothesis made is a tentative Adj, uncertain, experimental., and may or may not be true. As it is almost impossible to check every possible situation where a hypothesis might apply, in the third step scientids make a prediction using deductive reasoning ( generating a specific expectation from a generalization). Based on this prediction, in the fourth step experiments are designed and , in the fifth step , the results that have been obtained are analyzed. With the sixth step scientists deal with the two possible outcomes Result, consequances of the experiments: the results may or may not agree with the prediction. If the results disagree with the prediction, the hypothesis must be rejected and a new hyphotesis must be formulated. On the other hand, if the the results agree with the prediction scientists can accept the hyphotesis as true. This doesn’t mean that the hypothesis has been proved to be true, simply that it has not been disproved. The foundation of the experimental methods relies precisely on To depend ont his’s concept: a hypothesis can be accepted as true and not proved to be true. At this points scientists divulge their findings by means of scientific jounal , books, seminars, meetings. The seventh step is essential because it allows other people to verify the results . develop new tests or apply the new knowledge to solve other problems. See the scheme below for a better comphension: COMPRHENSION CHECK Put the steps of the experimental method into the correct order Drowing conclusions Forming hypothesis Reporting the results Analyzing datas Observing Making a predictions Perfoming experiments SPEAKING Based on the scheme of the previous exercise, illustrate eaxch step of the experimental method used using your own words.

Measurements are important both in everyday life and in science. Scientists often make measurements: to measure means to see how many times a basic unit is contained in the physical quantity that is going to be measured. If each nation had is own system of measurement, communication among scientists would be almost impossible. For this reason , a commonly accepted measurementsystem was adopted, so that all scientists can speak the same language and easily interpret the results they obtain. The International System of Units ( abbreviation is SI from the French Système international d’unites) is a worldwide measurement system based on the older metric system By the 18Th century, dozens of different units of measurement were commonly used troughout the world. In 1790 the French government asked the Academy of Science to designa simple decimal –based system of units.: the system they devised was the metric system. Since the 1960s, th international System of Units (SI) has been the internationally recognized standard metric system. It is a decimal system and it consists mainly of seven base units, each representing different physical quantities SI BASE UNITS Name Unit symbol quantity symbol metre m length l Kilogram kg mass m second s time t ampere A Electric current I kelvin K temperature T candela cd Luminous intensity Iv mole mol Amount of substance n Other units, called derived units, can be expressed using the base units. Some of the most common derived units are the pascal ( kg/m.s2) measuring pressure, the coulomb (A s) measuring electric charge, the square metre (m2) measuring surface, the cubic metre ( m3) measuring volume. Length is a fundamental physical quantity, and its base unit is the metre, while surface and volume are physical quantities that are derived from length. In addition to the SI units, a set of non- SI units are commonly accepted by scientists and in particular by chemists, who use them together with the SI units. Among these additional units are the minute ( for time) and the litre ( for volume). In order to indicate a multiple or a fraction of a unit a prefix may be added . Each prefix has a unique standardized symbol, accepted as part of the SI system. All multiples or submultiples are integer powers of ten. For example, kilo indicates a multiple of a thousand and milli-indicates a multiple of a thousandth. So a kilogram (ki) is 1,000 (one thousand) grams, a kilometre (km) is a 1000 metres, a milligram (mg) is 0.001 grams – that is to say there are 1000 metres, a milligram (mg) is 0.001 grams – that is to say there are 1000 milligrams in a gram. MAIN MULTIPLE AND SUBMULTIPLE IN THE SYSTEM Prefix symbol Meaning It multiplies by Giga- G Billions (109) 1,000,000,000 Mega- M Millions (106) 1,000,000 Kilo- k Thousands (103) 1,000 Deci- d Tenths (10-1) 0.1 Centi- c Hundredths (10-2) 0.01 Milli- m Thousandths (10-3) 0.001 Micro-  Millionths (10-6) 0.000001 Nano- n Billionths (10-9) 0.000000001 SPEAKING What kinds of units do you commonly use in everyday life?Have you ever heard about any units different from the ones you commonly use? Answer the questions and discuss with your classmates. READING COMPREHENSION Answer the following questions Where does the acronym SI come from? What is the SI system made up of?

However , it is not easy to describe energy, as it is something that we cannot hold or see: we can only see the results of its application. For example , we can see something moving which means that it has kinetic energy, or we can feel something is hot, meaning it contains thermal energy. Energy exists in several forms, such as heat pr thermal energy, electrictrical energy, kinetic or mechanical energy, nuclear energy, light energy, chemical energy and others. Two general categories of energy are especially important to chemists: kinetic energy and potential energy. Kinetic energy is energy of motion. For example, a football kicked towards a goal has a large amount of kinetic energy. Kinetic energy can be converted into other types of energy. In a hydroelectric dam, the kinetic energy of the falling water is converted into electrical energy. Potential energy is stored energy. Objects can store energy in terms of their position: a ball on a tree has go potential energy that is converted into kinetic energy once the ball fall down. The same concept is illustrated in the figure at the center considering the person on the bycicle like the ball. On the other hand , the human body stores energy in chemical bonds that are broken and release energy when the body needs it. In the same way the fuels used to run car or heat homes store energy that is released when chemical rections take place. The SI unit of energy is the Joule (J)., that is 1 kg.m2/ s2. We often speak about energy consumption., but this expression is not correct. In fact, a scientific law- the law of conservation of energy This important law is one of the basic laws of the physic and governs any chemical reactions. It states that the total amount of energy in a closed system, that is a system that is isolated from its surrondings, remains constant over the time. A consequence of this law is that energy can be neither created nor destroyed: it can only be transformed from one state to another.-states that energy transforms from one form to another and it is never destroyed. For instance, if you go for a ride in your car, you turn it on and it make noise. After your ride, you park your car and you notice that engine is hot , and that the fuel is less too. Here is what has happened: the chemical energy of the fuel has become kinetic, sound and thermal energy as well. MATCHING Match the two halves of the sentences Describing energy a) Released in case of necessity You can’t perceive energy b) According to the law of conservation of energy Kinetic, thermal, nuclear energies are c) can be difficoult Electrical energy may d) but only its results Potential energy is e) some of the existing forms of energy Energy can be transformed into other forms f) derive from kinetic energy. FIND THE QUESTION Write questions for the following answers: …………………………………………………………………………………………………………………………………… Matter and energy …………………………………………………………………………………………………………………………………… the ability to do work …………………………………………………………………………………………………………………………………… Becouse it contains thermal energy …………………………………………………………………………………………………………………………………… Kinetic energy and potential energy. ……………………………………………………………………………………………………………………………… When chemical reaction take place …………………………………………………………………………………………………………………………………… No, it isn’t correct. Energy is never destroyed. SPEAKING In groups talk about some examples of the various types of energy you can experience everyday life. Compare your answers with the other groups DEFINITIONS: Match the words in the first column to their definition Component a) Material for producing energy Energy b) To hit with the the foot Kinetic c) Machine to convert energy into motion To kick d) Ability to do work To convert e) Unit for energy Potential f) Relating to movement To release g) part of a total Fuel h) to allow to go, to set free Joule i) that may come into existence Engine j) To change form one form into ano 1.5 Heat and temperature Heat, or thermal energy, is the amount of energy in a system. For example, electrical energy is converted into thermal energy when we use objects such as toasters Toaster: electrical device for toasting bread, hair dryers A hand-held appliance thatc an blow worm air in order to remove moisture from hair; used for styling hair. or light bulbs Incandescent lamps. As it is a form of energy, the unit of heat in the SI system is the joule (J). Most people still use the metric unit, the calorie (cal). 1 calorie corresponds to 4.184 joules. It takes one calorie to raise the temperatures of one gram of water of 1 °C. The kilocalories (kcal), which is 1000 calories, is often used since the calorie is a rather small amount of heat. Temperature is not energy, but a measure of the average heat of the particles in a substance. When we measure the temperature of something, we actually are measuring the average kinetic energy of the individual Particle of a substance. On the other hand, heat is the amount of energy that goes from one substance to another. Temperature does not depend on the size or type of an object. For example, a small cup of water might have the same temperature as a large tub of water, but the tub of water has more heat because it has more water and therefore more total thermal energy. If we bring two objects with different temperatures into contact there will be a transfer of energy from the hotter one to the colder one until both of them reach the same temperature. The thermometer The term Thermometer is the instrument used to measure temperature. The SI unit of temperature is the kelvin (K), but many scientists use also Celsius or centigrade (°C). In the USA the Farheneit scale (° F) is commonly used. The relation between the different units is the following: Fahrenheit to Celsius ° C= 5/9 (°F -32) Celsius to Fahrenheit °F= 9/5 C° + 32 Celsius to kelvin: K= °C + 273.15 Water boils at 100 °C (373.15) and frezzers at 0°C(273.15 K). At a temperature of Absolute Zero there is no motion and no heat. It is the lowest temperature possible MULTIPLE CHOICE Complete the sentences choosing the right options Thermal energy is also called: 4) Temperature is: a)Heat; b) pressure; c) temperature. a) a form of energy, b) the measure of the particles in a substance The unit for heat in the SI system is : c) the energy transferred from a hot Calorie; b) kilocalorie; c) joule object to a cold object The metric unit for heat is : 5) Temperatures are measured using: Calorie; b) kilocalorie; c) joule a) a light bulb; b) a tub of water c) a thermometer WRITING: In your blocknotes describe easily what is reported in the picture above: The temperatures in the different scales and the connections among them SPEAKING: In groups discuss the situationsin everyday life in which you use a thermometer.

The volume of a solid object is a number obtained by determining the three-dimensional space it occupies. Thus, volume is measured in terms of length; width and height are not, for the purposes of science, distinct form length. Length provides one dimension, width provides a second dimension, perpendicular to the first, and height, perpendicular both to length and width, makes up the third spatial dimension. In any case, the three of them are merely expressions of length differentiated according to the direction. The basic unit for the Volume in the SI system is the cubic metre (m3), but a submultiple, the cubic centimetre ( cm3) is often used. 1 cm3 is equivalent to the unit of capacity of 1 mL. Even if capacity and volume can be referred to as the same concept, their definitions are different: capacity is how much a contaniner can hold, whereas volume is how much space on object displaces. The volume of solids with regular shapes can be measured according to the direct formulae. For an object that is irregular in shape the most basic method is to immerse the object in water following the Archimedes’principle Archimedes of Syracuse 8287 BC- 212 BC) is generally considered to be one of the greatest mathematicians of all the times. The principle take his name because he was the first to discovery the law. tHe stated that any object immersed in a fluid is buoyed up by a force equal to the weight of the fluid diplaced by the object , and for a sunken object the value of the displaced fluid is equal to its volume. . This procedure involves reading the volume water before and after immersion: the difference between them is the volume of the object . Temperature and pressure Pressure is an effect which occurs when a force is applied on a surface. Pressure can be defined as the amount of force acting perpendicularly on a unit area. The symbol of pressure is P. It is calculated by dividing the force by the area. Mathematically the formula is P= F/A.

According to Isaac Newton’s first law of motion, inertia is the tendency of an object in motion to remain in motion, or of an object at rest to remain at rest, at a costant velocity unless it is acted upon by an outside force. So, the more mass something contains, the more difficoult it is to put it into motion or to stop it from moving. The basic unit of mass in the Si system is the kilogram (kg) even if for chemists it is common to use submultiples, such as the gram (g). Mass is not the same as weight. The weight (P) of an object depends on the force of attraction (gravity) between the object and the place where this is mearured. Newton’s second law of motion defines weight as the product of mass multiplied by acceleration, that is the gravitational pull. Therefore, the weight of a body varies according to gravity, and it would be different if measured on the moon, while mass is the same throughout the universe. Because of its inestimable value, scientists usually speak in terms of mass rather than weight. MULTIPLE CHOICE Answer the questions choosing the right options 1) How do mass and weight differ?

The write a short paragraph. ACKNOWLEDGEMENT Sir Isaac Newton (1642-1727) was an English physicist, mathematician, astronomer, philosopher, alchemist and theologian, and he is considered to be one of the most influential people in human history and one of the founders of modern physical science. Among his achievements there are the famous three law of motion. The first law of motion, often called the law of inertia, states that an object at rest tends to stay at rest and that object in uniforms motion tends to stay in uniform motion unless acted upon by an external force. According to the second law of motions, acceleration is produced when a force act on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed ( to accelerate the object). It means that heavier objects require more force to move the same distance as lighter objects. Newton’s third law of motion says that for every action there is an equal and opposite re-action. That is to say that whenever an object pushes another object it is pushed back in the opposite direction equally hard. An example is the recoil of a fireman, in which the force propelling the bullet is exerted equally back onto the gun and is felt by the shooter. READING COMPREHENSION Answer the following questions: What nationality was Newton In what period did he live? What was his profession? How many laws of motions did Newton discover?

This property is density. The density of a substance (symbol , the Greek letter rho), is the ratio of mass to volume, that is mass divided by volume. Mathematically, the formula of density is = m/V. In the SI system, density is expressed by the derived unit kg/m3, but in chemistry we commonly use the submultiple g/ml, that is the same as g/cm3, or g/cc. It is possible to see density illustrated in everyday life by looking at the objects either floating or sinking in water. If an object such as a piece of wood floats on water it is less dense than water, if an object sinks it means that is has a higher density than water. Since the volumes of a liquids may vary with pressure and temperature, chemists usually specify the pressure and temperature at which they measure the density of a substance. In general measurements are taken at the normal atmospheric pressure (1 atm) and at the temperature of 20 °C: this temperature is close to room temperature and easy to obtain without a lot of heating or cooling. The density of water at 20 °C is 1 g/mL. Osmium and iridium almost have the same density and are the densest known substances. For problems on density is useful to remember the formula in the picture below. How instead can we measure unknown densities of bodies? It is shown in the picture below. TRUE OR FALSE Say of the following sentences are true or false, then correct the false ones. 1)The density of a substance is measured by multiplying mass by volume T F 2) kg/m3 is the same as g/mL T F 3) If an object sinks in water it means that it is denser than water.

Then find the volume occupied form each substance considering a mass of 10 g. Substances density Volume Hydrogen 0.000084 g/ cm3 Oxygen 0.00133 g/ cm3 Ethyl alcohol 0.79 g/ cm3 Water 1 g/ cm3 Concrete 2.3 g/ cm3 Iron 7.87 g/ cm3 Lead 11.34 g/ cm3 Gold 19.32 g/ cm3 Osmium 22.6 g/ cm3 1.9 Errors, Accuracy, Precision in Quantitative Measurements Every measurement has a certain degree of uncertainty. This uncertainty derives from the measuring instrument and from the skill1 of the person doing the measuring. Errors in chemistry are classified as systematic (or determinate) and random (or indeterminate). A systematic error is caused by a defect in the instrument or by an incorrect method or technique of the analyst. This type of error is often called ‘determinate’ because its cause can be determined and so it can be theoretically eliminated. An example of a systematic error is the one caused by a dirty glass pipette, which will always deliver less than the intended volume of liquid. A systematic error is characterised by the fact that it is repetitive and that it has a definite direction (either by defect or by excess – either positive or negative). Random or indeterminate errors are unavoidable and are due to random events occurring during the measuring process. Indeterminate errors can be minimized just repeating the same measurement many times. Since random errors can be positive as well as negative, the average of several measurements is going to be more reliable than any single measurement, and the value obtained with a series of measurements will tend to scatter2 around the true value. We must remember that a true value is that value that would be obtained by a perfect measurement, but since there is no perfect measurement in chemistry, we can never really know the true value. In order to get as close as possible to the theoretical true value, we must always consider the reality of error. In measuring, accuracy and precision are two important but separate concepts. Accuracy refers to how closely multiple measurements of the same quantity cluster3 around the true value. Precision refers to how closely multiple measurements of the same quantity cluster to one another. The classic illustration distinguishing the two is to consider a target: if the centre of the target (or bull’s eye) represents the true value of a measurement, arrows surrounding the bull’s eye indicate a high degree of precision. Arrows surrounding the bull’s eye and at the same time are very close to one another indicate both accuracy and precision. A simple but clear example is the following. Imagine you are counting the number of people in a room. If there are a lot of people moving about in the room the measurement might be difficult. You might count them three or four times and get a different value each time. So to be sure of the right measure you repeat the same measure at list 3 or 4 times and than make an average value. TRUE OR FALSE Decide if the following sentences are true or false, then correct the false ones 1) It is possible to obtain a perfect measurement. T F 2) There are two types of errors in chemistry. T F 3) A determinate error is the same as a systematic error. T F 4) An imperfection of the instrument may cause a systematic error. T F 5) Random errors have a definite direction. T F 6) Repeating the same measurement help get closer to the true value. T F 7) Accuracy and precision refer to the same concept. T F 8) Several measurements of the same quantity that are very close to one another but not very close to the true value, indicate a high degree of accuracy.

It is the speed of light! And what about the number 0.00000000000095 g? It is the mass of a bacterium1 ! Scientists, but also mathematicians, doctors and engineers often work with very large or very small numbers. A system was developed to help represent these numbers in a way that was easy to read and understand: scientific notation. Scientific notation is a method of expressing a value as the product of a number between 1 and 10 (except ten), and a power of 10. In scientific notation the numbers are written like this: a × 10 (it must be read “a times ten to the power of b”), where a is called the coefficient and b is called the exponent or the power of 10. The coefficient a has a value of at least 1 but less than 10 (1 ≤ a < 10). The exponent b is an integer, and it gives the order of magnitude of the number. The speed of light showed above, in scientific notation is written 3.0 × 108 m/sec (it must be read “three point zero times ten to the power of 8”), while the mass of a bacterium is 9.5 × 10–13 g (it must be read ‘nine point five times ten to the power of minus thirteen’). How does scientific notation work? How can we transform large or small number using scientific notation? For a large number the decimal point is moved to the left until only one digit remains on the left. The number of places the decimal point is moved gives the exponent. For example, the mass of the earth is 5,980,000,000,000,000,000,000,00 0 kg, while in scientific notation this number becomes 5.98 × 1024 because the decimal is put after the first digit, the zeroes are dropped, and the exponent is 24 because there are twenty-four places from the decimal to the end of the number. In the same way for a small number the decimal point is moved to the right until only one digit remains to the left of the decimal point. Therefore the number 0.000000000753 kg, indicating the mass of a dust2 particle, becomes 7.53 × 10–10, because the decimal is put after the first digit found moving to the right and the exponent is –10 because there are ten places between the decimal point of the number given and the decimal in scientific notation. Besides making it easier to represent very small or very large numbers, with scientific notation comparisons between different numbers become more evident considering the order of magnitude and calculations are easier as well. Below a table with all the conversion unit is reported. READING COMPREHENSION Answer the following questions. 1 Why was scientific notation developed? 2 How can you define scientific notation?

Scientists classify everything existitng thing in two main categories: matter and energy, which are considered to be, in this way , the main part of the universe. Indeed matter is really hard to define. A common way of defining matter is as anything that has mass and occupies space. In popular scientific books they give a simple explaination of what matter is: matter is the ‘’stuff’’ that every known object around us is made of. Matter is anything which has real existence: for example a car is made of matter because you can see and touch it, therefore it has real physical existence, it has mass and occupies space ,. Air, water, pasta , animals, milk, even you are made of matter.! But what is matter made of? Along the centuries, philosophers and scientists have speculated on the exact nature of matter. The idea that matter was made of very little buiding blocks was proposed by Demoscritus Democritus was one of the two founders of ancient atomist theory. He was born in Abdera , Thrace around 460 BC, died at the age of 90 and spent all his lihe studying, teaching and writing. in 5th- 4th centuries BC. This theory passed in the history as the particulate theory of the matter. Over time, the structure of matter was more exactly defined as we’ll see in the next pages, as we are going to examine in the next modules.. If you put some camphor into a drawer, even when the camphor has disappeared, the smell still persists. In the same way, some kitchen salt out into a glass of water tends to dissolve and disappear as well, but the water maintains a salty taste. The simple explaination of these phenomena is that matter is made up of small particles that cannot be seen but that show their existence, in this cases, with the smell od camphor and with the salty taste of water.

Solids, liquids and gases are the main and common states of the matter on our planet. Plasmas and Bose- Einsteins condensates represents the fouth and the fifth states of the matter. Plasmas are formed under conditions of extremely high temperature, while Bose- Einstein condensates are obtained when materials are cooled until they almost reach absolute zero. Mainly we found three states of the matter: solid, liquid and gas or vapor In solid, liquid and gases the particles behave in different way. At the macroscopic level , a solid has definite volume and shape. At the microscopic level, the particles that make up the solid are packed closely together and cannot move past one another. The particles are held together by strong forces , and so they can only vibrate next to each other. A solid cannot be compressed and it can only change its shape by force as when it is broken or cut. Liquids are fluid matter. They have a definite volume, but no definite shape as the forces between the particles are less strong than in solids. A liquid takes the shape of its container with the help of gravity. On the other hand, in outer spaces where there is no gravity, a liquid might float out of its container: the shape varies, but the volume remains constant. Liquids are also difficoult to compress because the particles are each close to the other and they can only move and slide past one another. A gas has no definite shape or volume , and it occupies the entire container in which it is confined. As the particles have extremely weak bonds, they move in continuous and random motions, only occasionally bumping into one another. Gases are able to fill up anything, also the atmosphere! Because the forces between the gas particles are so weak and the particles are spaced far apart, gases can be compressed. Example of gases forced into a small space are compressed air in a spray bottle or the carbon dioxide rushing out of a can of a fizzy drink. Squeeezed together, condensed …………………………….

Contents of the unit 3.1 The preview in the chemistry ; carbon, Hydrocarbon, Alcohols and Amines Living things are made up of chemical compounds which are divided into two main groups: organic and inorganic. The main interest of Organic chemistry is the study of the organic compounds, e.g of all the compounds in which there is the Carbon as main chemical element, which constitutes the organic compounds. The organic compounds that make up the cells, organs and tissues A part of an organism consisting of cells with the same structure and function. of living organisms are identical or similar to those found in non- living matter. Until the early 1800s the word ‘’organic’’referred to the chemical substances relating exclusively to living matter. This belief persisted until the German chemist Friederich Wohler synthetized urea in 1828. Up until then chemists had believed that the chemical compounds in living organisms were fundamentally different from those that occur in non-living things. This is why the chemical compounds associated with the living organisms were given the name ‘’organic’’: to emphasize their connection with life. Wohler proved that this theory was untrue: he found a very simple way to convert chemical compounds from living organisms into comparable compounds form non- living entities. As a result of Wohler’s research, the new definition of ‘’organic’’ came to be based on the observation that all these compounds had one property in common: they all contained carbon. Thus, the modern definition of organic chemistry, as the study of carbon compounds , was adopted. Since Wohler’s experiments hundred of organic compounds have ben synthetized and it is now clear that they are unique to living organisms. Organic compounds are very important in living things as they constitute the structures of the body and regulate their chemical processes. They can do this because of their complexity, which derives from the characteristic of the carbon atom. All organic compounds contain carbon but not all carbon compounds are classified as organic: they are usually made up of other elements such as oxygen, nitrogen, sulphur, phosphorus or halogen READING COMPREHENSION Read the text and answer the following questions How are chemical compounds classified?

WRITING Summarize, with your own word the content of the unit 3.2 The Carbon The carbon atom is one of more versatile element better kwon in the organic chemistry, as it can form four covalent bounds in its compouds, building long chains of atoms which are varied and complex. Peculiar of this element is the possibility to make covalent bounds with other carbon atoms forming in this way a carbonic skeleton that can be settled long the three different dimension in the space. Then Carbons can bound covalently also other atoms that are hydrogen, oxygen, nitrogen and so on. Why the Carbon was choosen by nature to perform four covalent bound in all the dimensions and to be among chemical elements, the king of known life?. Becouse it forms one of the more stable bound that are known by scientists and because it is one of more abundant element on the earth capable to form unique long structures and backbone that make them a very ‘unique’ element. A second important feature of carbon is that it can form very long chains. Theoretically there is no limit to the length of these chains: very large hydrocarbon molecules (polymers) can be made up of as many as 100,000 carbon atoms. Carbon chains can take the form of a sort of backbone – like the fatty acids- but they can also be branched- like in amino acids- or they can form rings of various sizes- such as in sugars.. Carbon can bound other elements (not only hydrogen) - with a single bound like in methane (1). In this case the bond and the relative organic compound are called satured, because the to the carbon are tied other 4 elements or groups. - with a double bound (2) -with a triple bound (3) In these last two cases we’ll have unsatured compounds or bounds The variety of forms that carbon chainscn take is a major reason why carbon compounds exibith so much isomerism .Isomers are molecules with with the same molecular formula but different arrangements of atoms that determine different physical and chemical properties. For examples there are two butanes with the same molecular formula (C4H10) but different arrangements of atoms: butane has its four carbon atoms bonded in a continuous chain, whereas isobutene has a branched structure.

Before the 20’s, chemists though that molecules with molecular weights greater than a few thousand could not exist. Hermann Staudinger, a German chemist who had studied natural compound such as rubber Elastic material obtained from certain plants and cellulose, challenged this view as he discovered that these compounds were made up of macromolecules composed of 10000 or more atoms The process in which relatively small molecules ( monomers) combine chemistry to produce a very large chainlike or network molecule ( a polymer) is better known as polimerization. The monomer molecules involved in this process may be all alike , or they represent two, three, or more different compounds. The resulting polymers have certain unique physical properties such as elasticity, high textile strength, or the ability to form fibres. Polymer poperties are determined by their shape and the way that molecules aggregates are arranged.: this is defined as morphology. Their molecular structure, conformation and arientation can determine whether polymers are fragile or resistant. Crystalline or amorphous material coexist in polymers: crystalline materials have their molecules arranged in repeating patterns while amorphous materials Have their molecules arranged in repeating pattern while amorphous materials have their molecules arranged randomly.Morphology of most polymers is swmi-cristalline, which means that they form mixture of small crystals and amorphous materials and melt over a range of temperatures instead of a single melting point. The glass transition temperature is the point at which the polymers hardens into an amorphous solid.Many important natural materials are made up of polymeric macromolecules and scientists have created polymer synthetic analogues in the lab, thus affording the world myriad plastic, textiles, and other polymeric materials. These materials are used as fiber, flexible films, adhesive, resistant paints and they have contributed to transform the modern society.

They can be natural or synthetized in a lab. Whatever the origin they find several application in everyday life. Do same research and find a many example as possible. Than share your result with your classmates 3.4 Addition and condensation polymerization Polymerization is the process through which monomers combine, forming stable covalent chemical bonds between them, to create polymers. There are two types of polymerization: addition and condensation so that we will have addition polymers or condensation polymers. Condensation reaction occur when a polymer is formed from a reaction that leaves behind a small molecule, often water. In addition reaction instead, monomers reacts to form a polymer without the formation of by-products.This kind of reaction are usually carried out in the presence of a catalysts which, in certain cases, exert control over structural details that have important effects on the properties of the polymer. Both addition and condensation polymerization can produce linear and cross-linked polymers. Linear polymers are composed of chainlike molecules without branched or adjacent structures. They are thermoplastic, which means that they soften or melt upon heating.They may be viscous liquid or solids with varying degrees of crystallinity. Some of them can be dissolved in certain liquids. Cross-lynked polymers, in which the molecular structure is network, are thermosetting resins that do not dissolve in solvents. These material are called thermosets because the crosslinking which makes their shape is made permanent by heat. This name distinguishes them from thermoplastics which are not crosslinked and can be reshaped once molded. Plastic are used as a common example of polymers, but there are many other materials which are also polymers, but there are many other materials which are also polymers, including proteins ( sich as hair, wool, nails, tortoise shell), cellulose in the paper and trees, DNA, silly putty, rubber. Many polymers, both addition and condensation are used as fibres.starch and cellulose are members of a class of compounds called carbohydrates which are polymers of glucose. Nylon is a generic designation for a family of synthetic polymers known generically as polyamides. A thermoplastic silky material, nylon, is used in many application including fabrics, rope carpets and musical strings.

They can be simply isolated form plants or animals, or they are created by modifying naturally occurring chemicals. The simpliest compounds in organic chemistry are hydrocarbons that conteins only two elements – carbon and hydrogen. The class of hyfrocarbon can further be divided in to subgroups depending on the way in which carbon and hydrocarbon atoms are joined to each other. In some hydrocarbons, for example, carbon and hydrogen atoms are joined to each other only by a single bonds. These hydrocarbons are known as saturated hydrocarbons. Alkanes are saturated hydrocarbons: this means that there are no double bounds in the molecule and they contain hydrogen bond and carbon atom only. There are many types af alkanes, the simplest being methane CH4, the natural gas, with just one atom of carbon. The smallest of these chemicals are gases at room temperature: methane, ethane and propane . Larger molecules are liquids : butane, pentane, hexane, heptane, octane, etc. The very largest ones are solids. They are all flammable. In other hydrocarbons, called unsatured, carbon and hydrogen atoms are joined to each other by double or triple bounds. Alkenes have two carbon atoms with a double bound between them, therefore they are unsatured hydrocarbons. Their name follow a similar pattern: ethane, propene, butane, pentene and so on. Hydrocarbons with one or more or triple bonds are called alkynes. They are together with alkenes insatured. Hydrocarbons derivatives are formed when there is a substitution of a functional group. These includes aromatic compounds, alcohols, ethers, aldehydes, ketones, carboxylic acids, esters, amines, amino acids, and carbohydrates.

They fall into different classes depending on how the OH group is positioned on the chain of carbon atoms. Primary Alcohols have two hydrogen atoms on the carbon joined to the OH groups. Secondary alcohols have only hydrogen atom on the carbon joined to the OH group Tertiary alcohols have no hydrogen atoms on the carbon attached to the OH molecule. Giving names to the alcohols follows two rules. The systematic nomenclature The systematic nomenclature corresponds to the IUPAC system, established as a unique way to name compounds. An alkyl group is group such as a methyl CH3 or ethyl CH3CH2. These are groups that contain chains of carbon atoms which may be branched. In primary alcohols the carbon atom carrying out the OH group is attached to one alkyl group, in secondary alcohols to two and in tertiary alcohols to three for alcohols adds the suffix-ol to the name of the parent alkane and uses a number to identify the carbon atom that carries the OH group. Instead the common names for alcohols are based on the name of the alkyl group, that is a group such as CH3 or ethyl CH3CH2 - These are groups that contains chains of carbon atoms which may be branched. In primary alcohols the carbon atom carrying the OH group is attached to one alkyl group, in secondary alcohols to two and in tertiary alchols to three. Therefore methanol (CH3OH) is commonly known as methyl alcohol. Ethanol (CH3CH2OH) is also called ethyl alcohol and 2- propanol (CH3CHOHCH3) is also named isopropyl alcohol. Methanol is highly toxic, whereas ethanol, or ethyl alcohols, is the alcohol associated with ‘’alcoholic’’ drinks. It is made by adding yeast to solutions that are rich in either sugars or starches. The yeast cells obtain energy from enzyme- catalized reactions that convert sugar or starch to ethanol in the blood can lead to coma or death. Alcohols have properties between the extremes of water and hydrocarbon: they are soluble in water when their hydrocarbon chain is shorter. Instead, as the hydrocarbon chain becomes longer, they became less soluble in water. Moreover they usually have higher boiling points than alkanes with similar molecular weight: ethanol, for example, reaches boiling point at 78.5 °C whereas propane , with the same molecular weight boils at – 42.1 °C. Phenols are another class of alcohols: they are strong disinfectants , whose derivatives are still employed today. The difference between alcohols and phenols is that the latter have the OH group attached to an aromatic ring, a structure formed by six carbon atoms. Wine is in general one of main source of alcohols COMPREHENSION CHECK Read the text and complete these sentence Alcohols are organic compounds with………………………….. 2)They are divided into three different classes according to 3)There are two different ways …………… 4) IUPAC names sounds like …………………. 5) Common names are based on…………………………………………….. 6) Some alcohols are dangerous :methanol……………………………………… 7)Alcohol solubility depends on ………………………………………………. 8) The longer the chain …………………………………………………………. 9) Another class of alcohol is ………………………………………………… WRITING Write full sentence to describe these items Alkyl group Systematic nomenclature Production of ethanol Boiling point of alcohols Phenols Position of OH group in phenols.

Alcoholic drinks are often mistakenly thought to have no dangerous effect, expecially if compared to drugs. Despite this common belief, alcohol can have as many terrible consequences as drugs on people who abuse of it . What do you think about that?Discuss it in your groups and make list of the possible reason why this habit is increasing. 3.7 Amines These organic compounds are produced by replacing one or more of the hydrogen atoms in the ammonia molecules (NH3) with an organic functional group. AMMONIA is a very dangerous molecules. It has a penetranting odour, it is toxic, reactive and it is a corrosive gas. Amines are classified as primary, secondary, or tertiary depending on the number of the hydrogen atoms of ammonia that have been replaced by organic groups. The replacement of one hydrogen atom by one functional group gives rise to primary amines; of two hydrogen atoms by two functional groups to secondary amines; of three hydrogens atoms by three functional groups to tertiary amines. Important amines include amino-acids, biogenic amines, trimethylamine, and aniline. Naming amines can be confusing because there are many variations depending on whether we follow the rules of the IUPAC nomenclature or whether we follow the rules of the IUPAC nomenclature or whether we use the common names: for example, the simplest amine CH3NH2 can be called aminomethano (IUPAC name) or methyl amine (common name). Amines can be aliphatic or aromatic in nature . Most aliphatic amines display some solubility in water . Solubility decreseas wuìith the increase in the number of carbon atoms. Aliphatic amines display significant solubility in organic solvent Organic solvents: chemicals, such as benzene, that damage tissues by dissolving fats and oils. Exposure to them may occur by inhalation or by skin or eye contact and be very dangerous. . The very small amines, like methylamine and ethylamine, smell very similar to ammonia, and bigger amines tend to have a distinctive fishy smell. Aromatic amines have the nitrogen atom connected to an aromatic ring. Aromatic rings: it is closed ring structure formed by six carbon atoms, with a single hydrogen atom attached to each one. It is also called a benzene ring Aromatic amines , such as aniline, have a diminuished tendency to engage in hydrogen bonding. Their boiling points are high and their solubility in water is low, but they are readily soluble in the common organic solvents, at leasts as far as primary aromatic amines are concerned. Some amines are major industrial chemicals used in making rubber, dyes, pharmaceuticals and synthetic resins and fibres, and in many other applications. Amines are also ubiquitous in biology. TRUE OR FALSE Read the text and decide if the sentences are true or false. Corect the false ones Amines are derived from alcohols by substituting hydrogen atoms The number of hydrogen atoms replaced by organic groups determines their type. Amino acids are examples of amines. All amines are named by using IUPAC nomenclature Amines can be aliphatic and aromatic , the difference being in the aromatic ring connected to nitrogen Aliphatic amines have a distinctive smell Aromatic amines are only soluble in water Amines are used in many field apart from biology.

Conclusions Students during the CLIL Course should assimilate the right terms for their interested field while they are speaking in that language. Discussion in loci of an experience in English language, the possibility of making some deduction in this language and moreover to know how to present the right result to all people, or even sharing opinions, observations, even though with the presence of BES in the classroom, is a poof that CLIL methodology is being activated and that is well working. Infact CLIL (krashen, SD (2003)), that is realized by reducing the TTT to augmentate the speaking one of alumni, should guarantee the apprehension of terms in the vehiculanting language and for all the alumni in the classroom. The presence in classroom of BES can give an help, being a kind of natural reinforce for the assimilation phase. (Dudley, 2008) With the aim to facilitate the apprehension of pupils and to make it with efficacy, (apprehension environment) it is necessary to organize pupils so that all of them can catch essentially the right words. In this sense the DSA can learn and improve languages, also if some mistake can occur. The comparison of results, infact, is possible if we consider the cooperative learning as the best way to facilitate contamination both in terms of knowledge and competencies, so to respect the actual Italian law that want an e- portfolio for each student as referred to the EQF framework. For sure, the best didactical methodology is that of learning by doing, based on the cooperative learning (Comoglio, 1996) both formal that informal because in that way we can teach collateral objectives- of citizenship and of competencies-. The right methodologies a teacher should use are role-playing or brain storming, so to reach the right targets. Other efforts to reinforce the apprehension of the learning object may come from the TIC, from the exploration of internet sites dealing with different types of topics to be shared among alumni ( for example actuality) and all the topic tied to the things we are going to teach. TIC, guarantee the formative success of all the DA alumni. Moreover it is interesting that teacher must think to furnish the same notions trough the gamification ( Cajola, 2014), according also to Winnicott Theory. This is an explaination on why people in adult life or during teenagers and childhood use the ‘games’ to reach the success. 5.
