Children learn all about the motion of machines as they embark on a series of entertaining educational experiments. The students find out what a workbench is and soon understand why engineers want to have one around. They create teeters. They use blocks to craft and change the level of ramps, and then observe an incline's effect on speed firsthand as they roll toy cars down. Electricity makes an appearance too, as the young science scholars inspect an electricity board and adjust electrical circuits to observe effect. They also investigate magnets and discover how magnetic forces can be harnessed to create motion.
