Question

The science club at Tracy's school is researching how temperature affects fish reproduction. They conducted a study to find out if raising the water temperature would decrease the number of bass eggs that hatched.

They gathered bass eggs from a local lake. Half of the aquariums were kept at room temerpature, and the other half were placed in a sunny window.

What is the independent (test) variable from this experiment?
Question 1 options:

The size of the lake.


The number of bass eggs that hatch.


The temperature of the water.


The number of aquariums.

Answer 1

Size of the lake I think

Answer 2

the size of the lake

Step-by-step explanation:

the size of the lake does not affect the experiment and is not affected by the other factors.

(hopefully I didn't misunderstand the question)

good luck!
