harkovskaia [24]

Answer:

a. Manipulated variable: TEMPERATURE

b. Responding variable: CRICKET CHIRP

c. Controlled variable: Same species of cricket

d. Hypothesis: IF the temperature is increased, THEN crickets will chirp more

Explanation:

Independent variable, also called the manipulated variable, is the variable that is changed or manipulated in an experiment. In this case, the independent variable is the TEMPERATURE.

Dependent or responding variable is the variable that responds to changes made to the independent variable. The dependent variable in this case is CHIRP OF THE CRICKETS.

Controlled variable is the variable that must be kept unchanged for all groups throughout the experiment. The controlled variable in this case is SAME SPECIES CRICKET USED.

Hypothesis is a testable explanation (via experimentation) to an observed problem or a given question. In this investigation involving Melissa, an hypothesis is: IF the temperature is increased, THEN crickets will chirp more.
