centimeters kilometers grams liters
I gave my students this multiple choice question: A researcher is conducting an investigation to determine if water temperature affects the growth rate of a certain type of fish in a lake. Which unit would the researcher use when determining the mass of the fish?

Only one answer is correct among these 4 choices:
- centimeters
- kilometers
- grams
- liters

Could you tell me which one is correct?

grams
