Science Lab in a Supermarket

We have been working through the experiments in Science Lab in a Supermarket, and today we spent some time learning about how water travels through plants.

In Experiment #1 we used colored water to observe how the water travels through the celery's capillaries.

In Experiment #2 we made a cut in one side of the celery stalk and then observed that the part above the cut section was not red like the other side after being in the colored water.
In Experiment #3 we compared two pieces of celery that had been left in the refrigerator for a few hours - one with water, and one without.
