Question
A student conducts an experiment to determine the speed of a toy car at the bottom of a ramp after it is released from different heights on the ramp. The student makes one measurement for each height.
What is one way that the student could improve the experiment?
Responses

The best way for the student to improve the experiment is to **perform multiple trials for each release height instead of just one**.
This improvement would help ensure that any anomalies or random errors are minimized, providing a more reliable average speed for each height. Multiple trials also increase the accuracy and validity of the results, allowing the student to draw better conclusions from the data collected.
