A biology class is studying the effect of temperature on the amount of growth of duckweed in an aquarium. What type of data will the class need to collect, and which tools will most likely be used?
Answer
A
They will gather qualitative data, using a thermometer and a hand lens.
B
They will gather qualitative data, using a meterstick and a flask.
C
They will gather quantitative data, using a thermometer and a balance.
D
They will gather quantitative data, using a beaker and a timer.
Explanation
The class needs quantitative data because temperature and the amount of duckweed growth can be measured and recorded as numbers. A thermometer measures temperature, and a balance can measure the duckweed’s mass, so choice C is correct.
