Physical Science for Children: All About Simple Machines

Product Description

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. This program is based on the concepts outlined in the National Science Education Standards for Physical Science: properties of objects & materials, position & motion of objects and light, heat, electricity & magnetism. This program is one of 11 volumes in the Physical Science for Children DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library for Children Collection.
