Repeat a Measurement
Name:
Date:
Today I am practising: using repeated trials to describe variation
1
Build a low cardboard ramp with adult help. Choose a toy car and mark one starting point.
2
Release the car without pushing. Measure how far it travels beyond the ramp with same-size blocks.
3
Repeat from the same start. Record a second distance.
4
Repeat once more. Record a third distance.
5
Which distance was greatest and which was smallest? Describe the difference.
6
Name one reason the distances might vary and one thing to keep steady next time.
- Keep the floor clear and the ramp low.
- Use the same blocks laid end to end with no gaps.
- Record variation honestly instead of changing numbers to match.
