Meter stick and graduated cylinder Stopwatch and meter stick Balance and metric ruler Balance and stopwatch
I gave my students this multiple choice question: Which tools are best used to determine the speed of a turtle as it walks along a path?

Only one answer is correct among these 4 choices:
- Meter stick and graduated cylinder
- Stopwatch and meter stick
- Balance and metric ruler
- Balance and stopwatch

Could you tell me which one is correct?

Stopwatch and meter stick
