Bart believes that mice given special food will become extra strong. He decides to perform this experiment by giving 10 mice in a special food for 14 days. He compared these 10 mice to another 10 mice that had normal food for 14 days. His test consisted of a heavy block of wood that blocked the mouse from getting treats. He found that 8 out of 10 of the mice given special food were able to push the block away. 7 out of 10 of the mice gievn normal food were able to do the same.
