Colors & light

Dinoguy asked me this morning "Mom, how do you make the color blue?"

I stumbled thru the idea that blue is a primary color and you don't make it, but that wasn't what he wanted to know. So we talked about making colors by squishing berries or flowers and making a paste to make the color, but I still wasn't answering his question right, so we turned to google. I learned that there are different types of primary colors and your printer makes blue by adding cyan and magenta. At this point I remember the light science kit my mom had given us and tell Dinoguy we should pull it out and it will help us.

So we pulled out the kit and started playing with light filters and flashlights and prisms and color mixing. The most successful way to mix the red, green and blue filters for us was by putting them on as glasses, the flashlight filters weren't as easy to see for us but we had a lot of fun. Trainboy joined in and we also played with other parts of the kit, making all sorts of cool discoveries. Dinoguy put on the green glasses and looked outside and pointed out that the sky wasn't green tinted but a brighter blue. This was a great way to show that green and blue make cyan, I showed him the kit diagram that we had tried to replicate and it made more sense, and we tried the red glasses and the sky was magenta!

We proceeded to try out layering the colored glasses, watching TV with the glasses, and playing with the flashlight and more. It was lots of fun.

That's a very cool kit! So cool that you remembered it and were able to use it for this purpose at just the right time it was needed!
