Leaves use the sun to power photosynthesis. This process turns the air and water into delicious sugar. A part of this process is chlorophyll. Chlorophyll absorbs sunlight and happens to be green. As it gets colder, it makes it hard for the chlorophyll to sugar up the trees. Chlorophyll stops being produced, and soon it’s all gone. That’s how the green goes away in the fall. Now, let me explain the colors­–the orange and red leaves. Leaves also contain other pigments. Without the chlorophyll in leaves, the other pigments come in and make the leaves have their orangey red colors. In tribute to the journey, all leaves take when changing colors, see if you can make your own journey from green to orangey.
