Gadgets and Gismos

This term we have been learning about simple machines. Some of the machines are gears, pulleys, levers, wheels and axles, screws, wedges and inclined planes. Our class split into groups and each group built something different with technic lego. In my group we built a windmill and the people that were in my group were Leah, Elly, Catherine and me. The windmill was hard to make and I was exited when we finally finished it. To make it work you have to wind the handle, then you flip the lever to unlock it and then the windmill turns all by itself. There are four different simple machines in the windmill.
