Trial 1:

1. Get a book and put a sheet of paper on top of it. Fold the paper as needed to keep the paper from sticking over the edge of the book.
2. Hold the textbook with the paper on top, horizontally about waist high.
3. Drop the book and paper so that they hit the floor flat.
4. note the observations.

Trial 2:

1. Take the same book in one hand and the paper in the other.
2. Hold book and paper at the same height.
3. Drop the book and paper simultaneously.
4. note the observations.

Before you begin Trial 3, think about your observations from trials 1 and 2. What did you observe to occur differently between the two?

Write one paragraph (complete sentences) explaining the difference between Trial 1 and Trial 2 observations.

Trial 3:

1. Form a hypothesis of what you think would happen differently if you took the flat piece of paper and the book that you used before and compared each to another piece of paper that is crumpled up tightly into a ball? Record that hypothesis on your worksheet.
2. Test your hypotheses by dropping the flat sheet and the crumpled sheet at the same time.
3. Now, drop the book and the crumbled paper.
4. note the observations.

Write one paragraph (complete sentences) analyzing your observations for all three trials. Did your observations (data) support or not support your hypotheses?
