This 3 page activity is a fun way to teach primary colors and secondary colors.
It starts off with a color wheel where students learn about the three primary colors. They can color this with crayons, pencils, watercolors, or paint. The second sheet is just the color wheel along. The last sheet can be printed twice. The first one to predict what color the two colors added together will make and a second one to conduct the experiment.
Science and art blended into one activity. The lesson could be done over a period of time or in one day.
