Make an organized chart or graph that shows the results of the
experiment.
Make sure journaling is done.
Conclusions:
Share information. Did the results support your
prediction?
What does this activity teach you about levers and work.
When was it easier to lift the pad of paper.
Extensions:
Design another experiment to show how levers work.
Design an experiment to lift a book 6 inches.
List any questions they might have. These could be used to develop
other experiments.
