Physical Science for Children - All About Simple Machines (VIDEO)

All kids know the word “work.” But they probably don’t understand that work happens whenever a force is used to move something - whether it’s lifting a heavy object or playing on a see-saw. All About Simple Machines introduces kids to the concepts of forces, work and how machines are used to make work easier. Six simple machines are presented using fun, real-life demonstrations and clear, colorful graphics: the lever, the wheel and axle, the pulley, the inclined plane, the screw and the wedge. Learn more about these simple wonders and see how they are the basis for most of the world’s tools and machines. Includes a fun, hands-on activity that lets kids test these ideas themselves using an ordinary see-saw.
