Red & Yellow make WHAT???

I love our neighborhood co-op preschool. I taught about mixing colors the other day and the kids loved doing this mixing activity in an ice tray with droppers. I thought we'd spend about 5 minutes doing it, but we actually ended up exploring with it for over 20 minutes! I was fascinated as I watched them learn and investigate. One of the highlights of motherhood for me is the opportunity I have to teach my children. I cannot get enough!
