Walking Water Experiment


Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. Plants use capillary action to bring water up the roots and stems to the rest of the plant.

Grade 4 students set up an experiment to observe ‘capillary action’ in plants.

We used two beakers filled with water and another one without any water. The they placed tissue paper in both of the beakers and observed the result.
