Homeschool Science: Water Movement Experiment

Water Movement

If you’re teaching your child biology, it can be difficult to show them just how plants function. They might understand that plants absorb sunlight, but it’s harder to grasp how plants soak up water from the ground. This is a simple and easy experiment to demonstrate that process. Here’s how it works:

What you need:

  • A large stalk of celery or piece of Napa cabbage
  • Clear container or glass
  • Food coloring

What to do:

  • Take either your celery or cabbage and slice it in half vertically.
  • Place a few drops of food coloring into your container.
  • Fill the container up with water about 1-2 inches deep.
  • Place your vegetable in the container and wait!
  • After about eight hours you’ll be able to see how the tiny tubes in the plant have soaked up the water and transported it all throughout the vegetable.

Doesn’t your creation look beautiful?  The parts soaked with dye that look like veins are actually transport tissue called xylem.  The xylem distribute water and some nutrients from the roots on up to the rest of the plant to restore water lost in photosynthesis and help it grow.
