Identifying a trend in temperature change over time:
Measuring the mass of a product of a chemical reaction:
Calculating a best-fit line for a data set:
Sharing data with classmates so they can check calculations:
Measuring the volume of water displaced by a solid object:

Answer 1

- Identifying a trend in temperature change over time: temperature probe/data logger and plot the readings (time‑series graph)
- Measuring the mass of a product of a chemical reaction: analytical/electronic balance
- Calculating a best-fit line for a data set: linear regression in a spreadsheet or graphing calculator (least‑squares fit)
- Sharing data with classmates so they can check calculations: shared cloud spreadsheet (e.g., Google Sheets) or shared drive folder
- Measuring the volume of water displaced by a solid object: graduated cylinder using the water‑displacement method (use an overflow can for large/oddly shaped objects)
