Analysis:

1) How do simple machines make our lives easier?

                 

2) Pick three of the objects from the lab and explain how it would be like without them?  How would you accomplish the tasks they help us with without them?

3) Go to your data table and label the fulcrum for each of your levers.

                  

4) Find three simple machines at home and add them to your Results.

5) a. Sketch a picture of each simple machine; use arrows to show the motion of each.  
    b. How does each simple machine change the direction, distance, or magnitude of a force?
