Celery Science Experiment – Transpiration* ages 3+

Celery Science Experiment 🌈 ages 3+ 🌈 Here’s a Simple Science Experiment you can do at home to demonstrate a process called transpiration.

MATERIALS NEEDED: (affiliate links)

  • Leafy celery stalks (the inner stalks work best)
  • Food coloring
  • Water

WHAT TO DO:

  1. Start by filling four small jars about halfway full of water.
  2. Add food coloring to each glass of water. (We made red, orange, blue and black.)
  3. Then add the celery stalks. Cut about an inch off of each stalk before placing in water.
  4. After 24 hours the leaves will have changed color to match the water.

WHY THIS HAPPENS:

The celery leaves change color because the tiny tubes (xylem) in the plant drink up the water just like a straw. This process of water moving through a plant to its leaves, stems and flowers is called transpiration. If you look at the capillaries you will see they now match the color of the water they were in. So cool! 👍🏻
