Spring is here and many kids are helping their parents and teachers grow plants and flowers. One of the most important jobs in growing plants is to water them regularly. My son helps my husband water the garden. As a result, by July, we have vegetables such as cucumbers, tomatoes, and green beans.
This Celery Experiment is great way to show kids how plants get water from their roots up to the leaves. At the end of the post, I will explain why this experiment works.
Let’s Get Started!
- Glass Jar or Drinking Glass
- Food Coloring
- Gather the materials
- Cut about one inch off the bottom of the celery stalk.
- Fill the drinking glass halfway with water.
- Put a few drops of food coloring into the drinking glass.
- Place the celery stalk in the colored water and let it sit over night.
- Rip open the celery to see how the color travels throughout the stalk
- You should see that the food coloring has traveled to the leaves.
Why it works:
- When you water a plant, the roots absorb the water from the soil.
- The tiny tubes in the celery or plant stem, called xylem, draw the water up from the roots like a straw.
- This process is called Capillary Action.
- Capillary Action happens when water climbs up the tiny tubes.
- The water droplets stick to the walls of the tubes and go upward.
- The water sticks to itself and pulls more water as it climbs up.
- Capillary Action lets water climb up to the various parts of a plant through the xylem tubes in the stem.
