How Plants Drink

How Plants Drink: an experiment for children of all ages. This fun (and easy) experiment will teach children how plants absorb water through a process called osmosis.

  • Supplies:
    • 3-4 clear containers (plastic cups, glasses, vases, or jars)
    • 3-4 fresh celery stalks with leaves
    • water
    • scissors
    • food coloring (3-4 colors)
    • gardening notebook/journal
    • paper (if using a binder) – copy paper, cardstock and/or 140 lb weight paper if using watercolors
    • pencil and eraser
    • art medium of choice (colored pencils, watercolors, crayons, or markers)
    • page protectors
  • Separate the celery stalks in 3-4 groups and cut about 1/2 inch off the bottoms. (Watch the video below prior to performing the experiment if needed.)
  • Fill each container with about 8 ounces of water.
  • Place 4-6 drops of food coloring into each container, one color per container.
  • Stand one stalk of celery in each container. You should see some results within 1-3 hours, but significant results overnight and over a few days.
  • Have your child predict what will happen to the celery. Ask them how the think plants get water? Will one color have more of an impact than another?
  • Compare the celery in the colors with an unused piece of celery to see the difference.
  • Cut the bottom of the celery to see where the water was transported into the stem. Pull back the fibers of the celery to see what the celery looks like on the inside. Document observations.
  • Place the page(s) in a protector when finished and include it in the garden notebook/journal.
  • Take pictures and tag #theabundantgarden on Instagram to share your fun and for an opportunity to be featured @theabundantgarden.
