8 Vocabulary in Context • Bacterial Growth Experiment
Ans:
Science Case Study:
A biology class sets up an experiment to see how temperature affects how fast bacteria reproduce in milk. The students test three identical milk samples under different conditions:
- Sample 1 is placed in a refrigerator at 4°C.
- Sample 2 is kept at room temperature at 22°C.
- Sample 3 is placed in an incubator at 37°C.
The students keep everything else the same: the amount of milk, the container size, and the testing time.
In this experiment, the temperature is the one factor that the students deliberately change. In scientific inquiry, this factor is the:
A Sample size, because it is the total number of milk containers
B Independent variable, because it is the condition purposely changed by the experimenter
C Observation, because it is recorded using the five senses
D Method, because it is the final conclusion written at the end
Student Pledge: I verify that all answers represent my own independent work.
