Find a thick board (2 x 6 I think) you will also need a block of wood to balance the board. Challenge the children to find a way to lift you in the air using only the board and pivet. (They will have to move the board off center and stand you on the short end.)

I asked an auto salvage to donate a part of a transmission for the kids to take apart and see the gears.

We are starting our Simple Machines unit in January. I am challenging the kids to create an invention and identify the simple machines used to make them. Last year I had one of my girls create a double toothbrush to save time brushing the tops and bottoms of her teeth. I also had a toy crusher and a kool-aide mixing robot. We displayed them at the Science Fair.

I love the edheads site too. The kids have a lot of fun with the game.
