Celery Experiment

1. Have your child put a few drops of blue food coloring in a jar of water. Explain that the food coloring represents pollution that can get into our water systems.
2. Use scissors to snip off the bottom edge of a celery stalk. Have your child place the freshly- cut end in the jar of blue water.
3. Place the jar on a windowsill in the sunshine where your child can check it daily. The blue water will begin to travel up the celery stalk turning the leaves at the top blue within a few days. The two of you will talk about the experiment on Day 5.
