Color Mixing and Light

The past week or so the kids have been working on a unit on Energy in Moving Beyond the Page. Today, we covered light and color. How mixing colors is different than mixing light.
So, we had the fun task of mixing red, blue and yellow water and making brown (unlike light, which would be white when mixed). Because I know someone will ask, I got the color mixing trays from Steve Spangler, which is my answer for anything that is science related. ;) I have had them since the first year we started homeschooling (four years ago!), but we haven't used them in a long time. So long, in fact, that the girls didn't remember them. They are a lot of fun and feel so.....scientific.

After we proved our hypothesis that all three colors together would make brown, they experimented with making orange, green and purple.
Then Joseph decided that he would try to recreate every color variation that he could fit in the tray.
