color wheel and water play

We made a color wheel that shows that the color light actually contains all the colors.


Here's a video of Jacob demonstrating and me explaining how it works.

Joshua is learning about fractions and the relationship between parts of something to its whole. I used measuring cups and water to show him that (2) 1/2s equal 1 whole, (3) 1/3s equal 1 whole, and (4) 1/4s equal one whole. We had a lot of fun, only took about 10 mins, and he really grasped the concept.
