What is the effect of the type of ball, a basketball and a soccer ball, on how high it bounces? You control the type of ball You measure the height it bounces IV – type of ball DV – Height the ball bounces
Height the ball is dropped from Surface the ball bounces on Both of these things should stay the same so that the results are reliable.
If a basketball and soccer ball are dropped from the same height, then the basketball will bounce the highest. Use the format: IF … say the IV being tested … then … predict a result.
Either provide research you have done, or say who you might consider an expert that you could go to for information. A basketball coach A soccer coach.
1. Gather Materials 2. Position a chair near a wall 3. Determine the height at which you will drop each ball and mark the spot with a piece of tape on the wall. 4. Have the tester stand on the chair and drop a ball from the marked height. 5. Have the spotter measure how high the ball gets after the first bounce. 6. Record data. 7. Perform three trials for each ball.

Do NOT just put IV, DV, and CV.
Always label your X & Y axis, provide a scale and a title, identify what the columns or lines represent, and draw the graph.
Tell me something that might have gone wrong that could affect the results. During one drop, the soccer ball bounced sideways. This caused the ball to not bounce as high.
Tell me what the results of the experiment were, if your hypothesis was supported, and include any additional information you learned. In conclusion, I found that the basketball did bounce higher than the soccer ball. My hypothesis was supported. I think that the material used to make the basketball helped make it bouncier.
Write a new testable question (or problem), that is similar to what you just did, but with one difference. A good rule of thumb: switch the IV with one of the CV’s. Which size of basketball will bounce higher, a full size ball or a half sized ball?
