Just Plane Simple

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.

Instructional Ideas

  • Provide different inclined plane, wedge, and screw dimensions and have the class calculate the individual simple machine's mechanical advantage
  • Bring in several compound machines and have class members find the simple machines that compose it
Classroom Considerations

  • The class should be familiar with the six simple machines
  • The third in a 10-part series
Pros

  • The plan has a clear set of learning objectives
  • Background information provides the information that a teacher would need to know in order to calculate the mechanical advantage of an inclined plane, wedge, and screw
Cons

  • Instructional strategies are not clear
