This video explains about coefficient, constant, variable and exponents. Useful for introductions to the topic and/or extension work. 

The amount of effort saved when using machines is called mechanical advantage (MA). Simple machines use mechanical advantage as a key property to their functionality, helping humans perform tasks that would require more force than a person could produce. We will use the lever as an example of a simple machine to illustrate the concept of mechanical advantage.

This online resource discusses the distribution of earth's water.

This video explains how to find factors.

This YouTube video will guide you through a fun activity where you will draw the earth's continents and oceans.

In this unit we will learn how these factors can affect the output of a simple machine. We will also learn about the difference between ideal mechanical advantage (IMA) and actual mechanical advantage (AMA), and how to apply your knowledge to calculate the efficiency of various simple machines.
