Color is a physical property and PreK chemists begin the year with a unit about color. In lab, we used color paddles to investigate how the primary colors (red, yellow, and blue) mix to create orange, purple, and green. Click here to watch a fun color mixing song.
We placed red, yellow, and blue color fizzers into cups of water. To make the secondary colors, we added one more color to each cup. Color fizzers are great because they do not stain, like food coloring.
This would be a fun time to pull out paints and mix colors at home.
