Answer:
1) The experimental variable is the different kinds of paper
2) (a) The independent variable are the different kinds of paper
(b) The dependent variable is the length of time the paper helicopters stayed in the air
The experimental control is ensuring that all paper helicopters are only flown in the hallway
3) The constant is the area she flew all her helicopters, which is the hall way
Explanation:
1) The experimental variable is the independent variable that is the variable upon which that is not altered by altering the other variables
2) (a) The independent variable is the variable upon which the recorded, measured, or dependent variable depends
(b) The dependent variable is the output variable whose value depends on the independent or input variable
3) The constant are the values that are kept the same during the experiment.
