Materials

-        6 books

(skip 1 line)

Procedure (Testing the Experiment)

1)   Drop 1 book from the table to the ground. 

Observations:________________________________

2)   With a partner, drop 1 book and 2 books from the same height at the same time. 

Observations: _______________________________

3)   Drop 1book and 3 books from the same height at the same time.

Observations:________________________________

4)   Repeat this procedure and fill in the Data table below.

Results

Put a check if they fall at the same rate and an “X” if they

fell at different rates.

	1 book	2 books	3 books
1 book
2 books
3 books

Analysis

1)   Did the single book fall faster, slower, or the same rate as the two texts?

2)   Was your hypothesis correct?  Why or why not?

3)   What should happen if you tried 1 book vs. 100 books?

4)   What should happen if you tried this with other objects?

5)   What is the independent variable?

6)   What is the dependent variable?

7)   What are two things you need to keep constant?

 Conclusion

(Write a summary of your experiment.  Was your hypothesis right?  What did you learn?  What could you do next time?  Was it fun?  How is this related to what we are learning in class?)
