Question 5 of 5 Students set up a controlled experiment. They put five
crickets in each of three identical containers. They set one
container to 15°C, one to 20°C, and one to 25°C. Then they
count the number of cricket chirps in each container
during 1 hour
What are two constants in this experiment?
A. The temperature of each container
B. The number of crickets in each container
s
C. The kind of containers used
D. The number of cricket chirps
SUBMIT

B. The number of crickets in each container.

C. The kind of containers used.

Explanation:

A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.

Controlled variable refers to anything or quantity such as group, person, event, etc., that is held constant by the researcher during an experiment and as such is limited.

In this scenario, the two constants in this experiment are;

I. The number of crickets in each of the three identical container.

II. The kind of containers used, they are all identical and as such would have the same properties.
