For thousands of years, people have been using simple machines to get work done. We still use these simple machines today, and we have learned to combine them to make complex machines. This unit teaches students about the six simple machines: lever, inclined plane, wedge, wheel and axle, screw, and pulley.
  • 4 Machines make it possible to move larger objects or to move objects faster or farther. Machines make work easier by adjusting the force or the distance to your advantage. They are used to push, pull, and lift. A machine can be used to increase the force or the distance, but not both. To get more force, you have to give up some distance.
