Jamal wants to know how fast his skateboard can roll down the ramp in front of his school. So, Jamal places the back of the skateboard even with the top of the ramp and times how long it takes before the front of the skateboard reaches the end of the ramp. After he records the time, he performs this procedure again four more times and calculates the average time. During his experiment,

Answer 1

Jamal's experiment demonstrates repetition.

Repetition refers to performing the same experiment multiple times to ensure that the results are consistent and to calculate an average. In this case, by timing how long it takes for the skateboard to roll down the ramp five times and then calculating the average time, Jamal is implementing repetition in his scientific process.
