Question: (What question were you trying to investigate?)

-If you use a lever and fulcrum to move a pebble and you change the location of your fulcrum, will it effect the distance the pebble can travel?

Question: (What question were you trying to investigate?)

- Does the distance an object falls change the amount of sound that is produced when it strikes an empty box?
Hypothesis: (What did you think was going to happen?)

-If the fulcrum is moved closer to the pebble, the pebble will travel less distance than if the fulcrum if moved further away from the pebble.

Hypothesis: (What did you think was going to happen?)

- We think more sound will be produced when the object is dropped from 18 inches because it falls further it is going faster.
Method: (How did you test your question?)

Steps/Methods
1.Place ruler at the six inch line on the edge of the table.

2.Place the pebble on the end of the ruler that is on the table.

3.Push (no tapping please PUSH!) the other end of the ruler that is not on the table.

4. Let the pebble fall onto the floor, and use the tape measure to measure the distance from under the table’s edge on the floor to the ball.

5.Record the distance and where you placed your fulcrum on a piece of paper.

6. Put the fulcrum at the the nine inch line and then repeat the steps 2-4 and record your answer.

7. Move the fulcrum to the three inch line and repeat the steps above once more and record your answer.

Method: (How did you test your question?)

- 1 . A pulley
2 . A string
3 . A solid object( like a rock)
4 . A hollow object
5. Ruler
6. voice recorder


1) We will use a pulley to raise an object exactly 6 inches above an upside down tissue box and we will record the amount of sound produced when we drop the object onto the box. 2) We will repeat the process at 12 and 18 inches.
Materials:

1 table (any size, but with no rounded edge),
1 small pebble no bigger than the first joint of your thumb,
1 non bendable twelve inch ruler, 1 roll tape measure, a pencil and a piece of paper.




Variable

-position of the fulcrum
