What is Capillary Action Video for Kids

 

This Video is about a cool science experiment that demonstrates the capillary action in plants.

                                      Capillary Action in Plants

We know that plants need water to survive but have you ever thought about how the water moves within the plant? They use water to keep their roots, stems, leaves and flowers healthy and prevent them from drying. Most of the time, they get the required water from the ground. Water moves through the plant by means of capillary action. It occurs when two forces, cohesion and surface tension which bind a liquid together and the adhesion force that attracts that liquid to another surface are greater than the gravity force. Through these bindings and forces, a plant sucks up the water.

In this experiment, we will put carnations in dyed water to figure out where the water goes.

Required Material: –

  • Water
  • Measuring Cup
  • Glass vase
  • Red food colour
  • White carnation (at least three)
  • Knife

Procedure: –

  • Measure a cup of water and pour it into the glass or vase.
  • Add 20 drops of food colour to the water in the glass.
  • By using knife, cut the bottom stem tips of all the carnations at a 45° angle. Shorter stems work better than smaller ones.
  • Place the carnations in the dyed water.
  • Observe the flowers immediately after you put them in the water.
  • Observe the flowers after several hours after you put them in the dyed water. Be sure to also observe their stems. You will see a darker shade of red colour.

It shows that water moves through the plant by means of capillary action. The water is pulled through the stem and then makes its way up to the flower.
