Repeat the investigation. Write a report of the results. Make a table for recording data. Make daily observations of the light bulbs.
I gave my students this multiple choice question: A class plans an investigation to see which brand of light bulb lasts the longest. Which of these steps should come first?

Only one answer is correct among these 4 choices:
- Repeat the investigation.
- Write a report of the results.
- Make a table for recording data.
- Make daily observations of the light bulbs.

Could you tell me which one is correct?

Make a table for recording data.
