SIMPLE MACHINES set is a combination of the basic 5 sets of Discovering STEM series and covers all Simple Machines mechanisms. These mechanisms offer a mechanical advantage and are crucial elements of many machines and devices. They are designed to multiply or reduce force increase or decrease speed and convert one type of motion to another. Build 60 working models that cover the subjects of levers the wedge the wheel and axle the screw the inclined plane the pulley as well as the more advanced gears and linkages! Kit comes with 5 multipage booklets filled with scientific principles experimental activities quiz and building instructions! Full colour images drawings and interesting facts. Thought provoking building challenges and exercises. Provision to write note results and draw conclusions.
