This week's simple machines


Today we worked on levers. True to form, Marley was only one step behind. She worked on her wheels in her maze. This she did all by herself.


After the girls were done with levers, Marley and I went on playing. Here we were checking out which made the wheel move faster and farther, the maze with blocks farther apart or closer together. I thought there would be more momentum with the blocks further away from eachother because they would fall harder. I was wrong. The maze with blocks closer together both times pushed the wheel further and faster. It was also the first maze to get to the wheel.
