What Kids Learn:
The color changing celery experiment is a fun STEAM activity for kids that teaches them about plant structures, water transportation, and the concept of capillary action. The celery has tiny tubes that carry water up to its leaves. This is like a magic trick called capillary action. As the water goes up, it takes the color with it, making the celery change colors. The objective of this experiment is to observe and understand how water is transported through the capillaries of celery stalks and how it affects the color of the celery. It’s a fun way to learn about plants and how they drink water!
