Capillary action

Fun transpiration experiments for learning about transport in plants. Includes colour changing flowers, capillary action experiment and a lego model

Capillary action happens because the adhesion force is more stronger then the cohesion force. Capillary action is an effect caused by the interactions of a liquid [e.g. water] with the walls of a tube, eg glass tube. Water climbs up, aginst gravity, in a glass tube because of the strong hydrogen-bonding interactions between H_2O, id est the hydrogen atom and the surface of the glass (glass contains SiO_2; oxygen from SiO_2 is typically bonded to hydrogen from water). On the video below is…

Learn how to separate plant pigments using paper chromatography. Experiment with different leaves to see the wide range of pigments!

Get ready to amaze your kids with walking water science experint. This easy, colorful capillary action activity is prefect for preschool and up!

Staining Science: Capillary Action of Dyed Water in Plants Have you ever heard someone say, "That plant is thirsty," or "Give that plant a drink of water."? We know that all plants need water to survive, even bouquets of cut flowers and plants living in deserts. But have you ever thought about how water moves within the plant? In this activity, you'll put carnations in dyed water to figure out where the water goes. Where do you think the dyed water will travel, and what will this tell you…

Learn about capillary action, including what it is and how it works. Get capillary actions examples in everyday life.

We had fun with this experiment. It was very cool to watch the colours change! I used food coloring and cabbage leaves to show the kids how plants …

A simple, colourful experiment that demonstrates the capillary action in plants using just a few paper towels, food colouring and water. It also teaches you how to make some beautiful paper towel f…
