Our class today focused on pulleys and wheels. We began by using pulleys to send jokes and riddles to each other across the room. Then, we used pulleys to lift heavy buckets starting with just one pulley which was tough, then two pulleys which was easier, and finally a block and tackle which was the easiest. Next, our focus turned to wheels. Students used a dolly to push a basket of heavy books across the room. Then, they took turns sitting on the dolly themselves and pushing each other from side to side. And our final minutes of class were spent making pasta cars. Simple machines are so much fun!
