We'd gotten a number of books out of the library that had to do with science experiments and so we played around with the books.
We started with Everyday Science Experiments in the gym
We listened to our heart beat, leaned hard against a wall and learned that afterwards our arm will go up all on it's own! We stood really close to a wall and learned how hard it was to lift the outside foot from the wall.
Then we moved on to Everyday Science Experiments in the Kitchen.
