Title: Which Kind of Ball will Bounce the Highest
Aim - what are you going to investigate?
To investigate which of the four balls; golf ball, ping-pong ball, tennis ball and rubber ball will bounce the highest after being dropped from either a 100 cm or 50 cm height.
Hypothesis - what do you think will happen? A generalisation that links the independent and dependent variables (you may use and IF THEN statement.
Compared to 50 cm, when any of the balls is dropped from 100 cm it will bounce higher because the ball will have more kinetic energy. The ping-pong ball will bounce the highest out of the four balls then the rubber ball, golf ball and tennis ball in order from highest bounce to lowest.

What do your results tell you? Are there any relationships, patterns or trends in your results?
The results show that on both experiments the golf ball bounced the highest, then the rubber ball, ping-pong ball and tennis ball which bounced the least highest. This suggests that from any height these four balls are dropped from, the results will be the same with the golf ball bouncing the highest.
The results also show that the material of the ball makes a lot of difference because both the tennis ball and golf ball were similar weights but their heights reached were very different.
Can you explain the relationships, patterns or trends in your results? Try to use some science ideas to help explain what happened.
The four balls all reached a different height on the 2nd trial but they were in the same order from highest to lowest. This is because although they were dropped from a lesser height and had less kinetic energy, each ball had the same amount of kinetic energy which mean they would bounce depending on the same factors at the first trial (eg. the ball material).
The reason the golf ball bounced higher than the tennis ball is because the golf ball is made of rubber and plastic, which will bounce better than the cotton and nylon that the tennis ball is made
