Color-Climbing Celery

Colored veins/petals appear. Ask students to predict what will happen. Show a stalk prepared earlier in colored water; cut stem if desired. Key idea: Water moves through narrow plant tubes by capillary action and transpiration. Ask: Where did the color travel inside the plant? Safety and cleanup: Teacher handles cutting. https://www.pbs.org/parents/crafts-and-experiments/rainbow-celery-experiment
