In science my class did an experiment about balls and me and my small group tried to predict where it would bounce up first and see and then do it 3 times, then add them all up and divide them by 3 to see the most average it would bounce up first
Aim - to investigate how many number can we get whilst the ball is bouncing up [first bounce]
Hypothesis- to investigate if you drop a ball with a little bit of pressure would it go up more when it bounce or does it just stay the same
My groups results [these is measured by centimeters]
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
Method
we start at 20 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 by using our eyes and try to predict where it will land]
Key Variables
Control Variable = Surface where you dropped the ball from
Independent Variable = When you keep changing place where dropped the ball from, The number where you dropped it from
Dependent Variable = The height of where the ball bounced/ Ruler I think
