The Robins and Bluebirds have been busy experimenting with Simple Machines and are proud to display their hard work at The Simple Machine Expo today! Simple Machines make work easier and include the Lever, Wheel & Axle, Pulley, Inclined Plane, Wedge and Screw. Students are discovering the science behind catapults, balance boards, flag poles, rollercoasters, balance scales, seesaws and more. Simple Machines are everywhere – just ask a GPS Kindergartner!
