Changing Colors

Learn about nutrition with carnations and color!

A fun way to teach kids about how our body uses the nutrients we give it is with a simple experiment involving carnations and food coloring.

You’ll need several white carnations (as many as you’d like to experiment with), food coloring, water and a few vases.

The experiment

Fill the vases up about a quarter of the way with water. Add about 10 to 20 drops of food coloring and stir it into the water. Cut off about an inch from the bottom of the stem of the carnation and place it in the vase. Now we wait. You can fill several different vases with different coloring if you’d like.

Every few hours, check back on the carnation to see if anything has changed. You might want to have your child keep a small notebook of observations.

How long does it take before the coloring starts to appear on the carnation’s petals? Consider coloring a picture of the carnation every few hours to note the changes. You can also use your phone to take pictures along the way so your child can compare the flower’s progression.  Does the carnation ever fully change colors? If so, how long does that take? Does the carnation stop changing colors? Do some colors move faster to the flower than others?

So how does this relate to your body?

Think of the colored water as the food and nutrients you take in. Think of the carnation as your body. When you eat or drink, it’s not just about how yummy it tastes. It’s about nourishing your body. The food travels down your throat into your stomach. Think of this like the stem of the carnation. The food is digested in your stomach and then the nutrients are sent out to your body to give you energy, strength and help you grow. Just like the flower sends the colored water out to the petals.

Unlike the carnation, your body needs more than water to live. Your body needs a well-rounded diet of fruits, vegetables, whole grains, and proteins. It’s also suggested to eat a colorful diet. Can you try to eat all colors of the rainbow?
