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.
