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.
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.
