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 number of crickets in each container
B. The number of cricket chirps
O C. The kind of containers used
D. The temperature of each container
A and C, Explain: the cricket chirps and temperatures would be considered independent variables. while per the definition, “A constant is the part that doesn’t change during the experiment” meaning that both A and C would be considered constants
