Every machine has moving parts, and ultimately those moving parts make work easier for you and me. We looked at many different types of machines in class, and discovered that in order to get those parts moving, they required energy. We slowly discovered how each machine has an action put in to get the machine moving, and then there is a resulting motion. The resulting motion made something easier.
The machines we looked at in class were glue sticks, mechanical pencils, can openers, and egg beaters. We then compared these everyday machines to the more complicated machines we read about with Leif--windmills and wind turbines. Windmills catch wind energy and turn it into useful work like pumping water, grinding grain, or lifting weight. Wind turbines transform wind energy into electrical energy that we can use to light and heat our homes.
