My simple machine is a wheel. It works in many ways to make our life better. if cars didn't have wheels, how would they move around? Most of our transport involves wheels! Bikes, trains, cars and even planes! Wheels are amazing! My compound machine is the can opener! It uses lots of little simple machines that work together to open a can. We use the can opener alot to make different types of food. Canned food is one of the many foods that dosen't expire easily! Withouyt the can opener, how would we eat tinned baked beans or tinned fruit? Or lives are truly changed bu this great invention!
