Weather: Fill the cup with water. Put shaving cream on top for a cloud. Explain that when clouds get really heavy with water, it rains! Then put blue food coloring on top of the cloud, and watch it rain. Just in time or my weather unit this week! I thought this was a really cool experiment that I must do with my students to introduce a weather topic or even the water cycle! - Oh my trendy!
Color Theory Experiments: Older students can record the formula for each new color they make (2 drops red + 3 drops yellow = color name) Include a color wheel with primary, secondary, and tertiary colors
