Find out if the temperature of the squash ball makes a difference on how high it bounces on the same surface area.

Extracts from this document...

Introduction

Aim: In this investigation I intend to find out if the temperature of the squash ball makes a difference on how high it bounces on the same surface area. Prediction: I predict that as the temperature rises the particles inside the ball will move faster. With the ball at a higher temperature it will cause a high air pressure, so the ball should bounce back up higher. The heat will create more molecules in the ball they will start vibrating more rapidly, this will cause more energy with the ball having a higher energy it will bounce higher as the temperature increases. ...read more.

Middle

For a fair test I will use the same surface, keep my measurement the same and repeat the experiment twice I must make sure I keep those settings for a fair test otherwise there is no point in the experiment and it would fail, making sure it is a fair test I can get my results accurate. I will record my results in a table and calculate an average. The range of temperatures I will be using goes from 8 to 90 I have used 8 different temperatures and range in about 10 between them. Results: Temperature Distance (cm) ...read more.

Conclusion

In my results I used a wide range of temperatures so it showed the effect of temperature on the ball more. My graph proved my prediction correct. I thought I had enough results to prove the purpose of the investigation. I stuck to my method the whole way through and completed the experiment successfully. If I had any odd results I could say that I had only one; when the temperature was 77 the ball only bounced 43cm I would of expected to bounce a little higher, but pleased I only had 1 odd result. I think my results were reliable and I'm confident with my conclusion. INVESTIGATION TO SEE IF TEMPERATURE EFFECTS THE HIGHT THE BALL BOUNCES. ...read more.

    24�c to 100�c. This will be in 10�c intervals and I will record each in a results table. I will record how high the squash ball bounces each time. I will be leaving the ball in the beaker for one minute each time so it gains the water's temperature because rubber is a very poor conductor of heat.
