Color Changing Celery: Fun Celery Dye Experiment For Kids

Color Changing Celery: Fun Celery Dye Experiment For Kids

By: Teo Spengler

It is never too early to get kids interested in plants and the ways Mother Nature has equipped them to survive. Even young tots can grasp complex concepts, like osmosis, if you create experiments that hold their attention. Here’s one to get you started: the great celery dye experiment.

This is a great family project that involves celery sticks that turn colors as they absorb colored water. Read on for instructions on how to dye celery.

Celery Dye Experiment

Kids know that garden plants don’t eat or drink like people do. But an explanation of osmosis – the process by which plants uptake water and nutrients – can quickly get too confusing for young children.

By engaging your younger kids, even toddlers, in the celery dye experiment, they will get to see plants drinking instead of hearing an explanation of it. And because changing the color of celery is fun, the entire experiment should be an adventure.

How to Dye Celery

You don’t need much to get this color changing celery project underway. In addition to celery, you’ll need a few clear glass jars or cups, water and food coloring.

Explain to your children that they are about to do an experiment to see how plants drink. Then have them line up the glass jars or cups on the kitchen counter or table and fill each one with about 8 ounces of water. Let them put 3 or 4 drops of one shade of the food coloring into each cup.

Separate the celery packet into stalks with leaves, cutting a little off the bottom of each stalk. Pull out lighter leafier stalks from the center of the bunch and have your kids put several in each jar, stirring up the water and blending in the food coloring drops.

Have your children guess what might happen and write down their predictions. Let them check on the color changing celery after 20 minutes. They should see the dye color in little dots in the tops of the stalks. Rip open one piece of celery of each color to trace from the inside how water is mounting.

Check again after 24 hours. Which colors spread best? Let your kids vote on the prediction that came to closest to what happened.
