HTWW Simple Machines

This is a slideshow on simple machines, we did it for our HTWW inquiry. I learnt that levers make lifting things easier. I also learnt that the more pulleys you have, the easier it is to lift. Inclined planes are everywhere. I wish that I could have learn more about gravity and how that relates to our strength. I wish that we had more time to do this, as I enjoy science.
