It is plane to see that simple machines help reduce the force needed to perform a task. This resource introduces three of the simple machines--the inclined plane, the wedge, and the screw, and the formulas in order to be able to calculate the mechanical advantage of each.
Simple MachinesRamps, levers, screws, pulleys, and more! Help your students learn about simple machines by having them understand how they conserve energy, how they are used in our every day lives, and how to build their own. Some resources get into combining simple machines to form compound machines.5th - 8th Science
