Simple Machines



Today we were engineers! We had to work with a partner or on our own to devise a plan using simple machines to help a large dog with back problems get into the back of a truck. The dog cannot jump on its own, and is too heavy for the owner to lift. We had to draw our machine or solution and write about how it works. We had to use our new knowledge about simple machines to design a compound or complex machine to do this job.
