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

-What effect does wind have on a moving soccer ball?


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

- If you increase the amount of air in a balloon, will it turn the axle it is attached to at a greater speed?
Hypothesis: (What did you think was going to happen?)

- The wind will affect the soccer ball by moving it farther in the direction the wind is blowing.


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

- When the balloon is inflated twice as much the axle will spin faster.
Method: (How did you test your question?)

-

(1) Get the soccer ball, masking tape, tape measure, and the large fan and go into an open space. Set up a line of masking tape on the ground. The kicker will always be behind this line.

(2) Move the fan (variable) just to the right of the soccer ball and move it far out. Make sure the ball can reach the fan if you kick it.

(3) Turn on the fan and kick the soccer ball so its direction crosses the path of the fan’s wind. Measure how far to the left the ball has traveled from the site of the kick.

(4) Move the fan (variable) so it is blowing against the ball when it is kicked. The person (helper) holds the fan far so the soccer ball won’t hit it but close enough were the fan can effect it.

(5) Now, when you’ve adjusted the fan, you can kick the ball. Record how far the ball went.

(6) Now, move the fan (variable) so it is right behind the kicker. Kick the ball and see how far it goes.


Method: (How did you test your question?)

- 1. Inflate the balloon to stretch it out a bit. 2. Slip the nozzle end of the balloon over the end of the straw farthest away from the bend. Use a short piece of plastic tape to seal the balloon to the straw. The balloon should inflate when you blow through the straw. 3. Bend the opposite end of the straw at a right angle. 4. Lay the straw and the balloon on an outstretched finger so that it balances and mark the balances point. Push the pin through the straw at the balance point and then continue pushing the pin into the eraser of the pencil and finally into the wood itself. 5. Spin the straw a few times to loosen up the hole the pin has made. 6. Blow in the straw to inflate the balloon to about the size of a golf ball, then let go of the straw and note the speed it spins. Repeat, but inflate the balloon to about double the size of the first trial. Note if the speed increases.
