How It Works

The stem of a plant is strong and sturdy to help the plant stand up straight. It also lets water and other nutrients flow up it. The stem in this activity acts like someone sucking on a straw to drink colored water. Once the colored water gets to the leaves the food coloring builds up there and we can see the color of the leaves change because of the food coloring. The process is slow, but after a few days, the leaves are colorful!
