Course Objectives

This free sample of the course "Getting to Work with Simple Machines" introduces students to the screw, one of the six simple machines.

In this lesson, students will:

  • learn about the components of the screw
  • understand how screws help us to do work
  • relate screws to the force of friction
  • compare the role of a screw with that of a nail through experimentation


FULL COURSE OBJECTIVES

This course seeks to introduce students to important concepts in the physical sciences.

By completing this course, students will:

  • understand that work is the product of force and distance
  • calculate force in Newtons using the equation F = M x G
  • understand that forces (such as gravity and friction) are always exerted upon us, even when we are at rest
  • understand the relationship between Newton's laws of motion and universal law of gravitation and simple machines
  • understand that machines give us a mechanical advantage
  • identify the 6 simple machines in their everyday lives
  • use Archimedes' law of levers to solve real world problems
  • build and experiment with simple machines
  • calculate the mechanical advantage of inclined planes
  • identify ways that simple machines have been used throughout history


While the mini-course is appropriate for students as young as 8, the full course is course appropriate for students aged 9-12.
