SCIENCE : Project 1

My groups results whilst doing the bounce ball experiment, what we had to do was either record and put it in slow mode for proof of where it bounce first or you could try to predict where it bounced backed again:

Aim : To investigate the relationship between the height a ball is dropped from, and the height of the ball's first bounce.

Hypothesis: A guess how height the ball will bounce and half of the height.

20 = 15 - 14 - 16 = 15

40 = 22 - 31 - 27 = 26

60 = 38 - 41 - 40 = 39

80 = 52 - 54 - 58 = 54

100 = 60 - 64 - 67 = 63

 Conclusion:

overall we got around 65% to 75%.which was a weird result. the ball bounced over where we drooped it

from .next time i'm going to use a white tape because the ruler was too dark to see.

 We start at 100 and bounce the ball then go up by 20 or 10 then we add the 3 numbers that we get while

bouncing then divide them by 3 to get the results [the numbers that we got are somewhat not accurate
because we did using our eyes and try to predict where it will land]

Key variables

control variable = Surface where you drooped the ball from

independent variable = When you keep changing the place where you drooped the ball from

dependent variable = The height of where the ball bounced
