Simple Machines
We are having lots of fun studying simple machines. There are so many things we use every day that I would have never considered simple or even complex machines. Did you know that a non-electric can opener is made up of 4 simple machines: a wedge (the cutting blade), a lever (the 2 handles you squeeze together), a wheel and axle (the handle that turns), and gears? Wow! I am so impressed by how quickly the second graders are picking up all this information!
