This week the fifth grade students have been working on simple machines in science. There are six simple machines that we are focusing on. There is a wedge, a wheel & axel, a pulley, a lever, a screw,and an inclined plane. We used our brains to make a fun playground using all the simple machines in a different way. 5th grade students have learned how all the simple work together to make compound machines.We learned that we use simple machines every day in our lives like a butter knife.
