Celery Experiment

Celery Experiment

Do you like to water the plants in your home or garden? We already know that plants and flowers need water to grow and live but what happens after that? Find out what really happens when you sprinkle that water, with this fun experiment that shows how plants absorb water!

What You Need:

• Tall clear glass or jar
• Water
• Red food coloring
• Scissors
• Celery stalk with leaves
• Printable Observation Sheet

What You Do:

1. Fill a tall, clear glass or jar half-full with water.
2. Add a few drops of red food coloring and mix well.
3. Trim the bottom of a large stalk of celery, leaving the leaves on the stalk.
4. Place the celery stalk in the glass or jar. Leave overnight in order for the stalk to “drink” the water.
5. Print out the observation sheet for this activity, and follow the instructions given. 
6. The next morning, observe what has happened.
7. Complete the “after” portion of the observation sheet. Draw a picture of what happened and write a sentence to sum up your findings.

Now that you have seen how plants absorb water, try this experiment in a new and different way!

• Take a celery stalk with leave and trim the bottom.
• Using the scissors, make a slit up the middle of the stalk stopping an inch below the leaves.
• Fill two glasses half-full with water. Add a few drops of food coloring to one jar or glass and add a few drops of a different color food coloring into the second jar or glass.
• Mix the food coloring in each glass and place the glasses next to each other. Put one-half of the celery stalk in one glass and the other half in the other glass. Leave overnight.
• The next morning, observe what has happened. What changes do you notice about the celery and the water? What is different about this experiment compared to the first one? Each half of the celery stalk will have absorbed the colored water and the two colors will have blended together as they moved up inside the stalk!
