Capillary action

In this activity, students see capillary action . . . in action! Watch coloured water flow up a celery stalk, showing just how water moves from the roots of plants to their leaves. All plants need water to survive. Plants use water to carry nutrients to their roots, stems, leaves and flowers and to prevent them from […]

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…

Is it magic? No...it's the amazing, gravity-defying capillary action experiment! Kids will love this dramatic and enlightening science fair project.

Science experiment #9 Take two jars, two food coloring, and two pieces of lettuce, put the food coloring in the jars then the lettuce and watch the color grow up

The current pandemic will likely inform the future of things like hospital design, emergency planning, supply chains, international trade and manufacturing, workplace technology, transportation, sporting events, and even (perhaps especially) how we educate and learn. As a guy named Einstein reminded us, we can’t solve our problems with the same kind of thinking we used when we created them.

This simple celery food coloring experiment allows you and your child to learn about capillary action and the circulatory system.
