This series is designed to introduce students to the six simple machines, work, and energy. Axle the Robot will help present the key concepts and principles associated with work, energy, and the simple machines. This 3D animated character will illustrate concepts presented in the four videos that make up this Unit of Study. He will reinforce vocabulary and demonstrate key ideas. Tools and situations common to students' experiences will be used to further explore these ideas.

1. Compound Machines.  This program demonstrates how the six simple machines can be found in very complicated machines and equipment. From giant construction equipment to tools found around the house. The six simple machines are the basis for all other machines. Many examples of compound machines, machines that use two or more simple machines, are presented and analyzed by Axle the Robot.

2. Inclined Plane, Wedge, Screw.    Just as the lever, wheel and axle and pulley are related, so too are these three simple machines. The wedge may very well be the most common simple machine as it is any device that has a sharp or cutting edge. Axle the Robot will demonstrate how these simple machines help to do work faster, make work easier, or change the direction of effort.  

3. Lever, Wheel & Axle, Pulley.  These three simple machines, as different as they may appear, are actually closely related. The principles behind each of these simple machines are illustrated and demonstrated with common situations and tools.

4. Work & Energy.  Students learn that work to a scientist is very different from work as we think of it. To a scientist, work is accomplished when an object with resistance is moved a distance. Potential and kinetic energy are discussed and illustrated, as well as forces such as friction that slow objects down.
