Science Simple Machines

In class we have been learning about six simple machines: a pulley, screw, wheel and axle, inclined plane, wedge, and lever.  Students are thinking about a simple task like turning on a light switch or watering a plant and using ten or more steps involving simple machines to complete a task.
