This past week while reading about Egypt and the Pharaoh's, we learned about Ramses II, who had statues of himself built all over Egypt.
Working on that idea, Danya and Gloria each made a statue out of white playdough. Last Christmas we stocked up on playdough, getting about 4 cans of each basic color (red, blue, yellow, green, white). We give them only one color to use at a time. That way they don't mix the colors together creating a dark swirly lump of no particular color. We got the idea from our church nursery.
Anyway, they had fun experimenting to figure out how to get the statues to stand up, and how long the arms could be before they fell over or fell off. I think they both did pretty good.
