A scientist plants two rows of corn for experimentation. She puts fertilizer on row 1 but does not put fertilizer on row 2. Both rows receive the same amount of sun and water. She checks the growth of the corn over the course of five months. Q9) What is the independent variable in this experiment? Why is this variable independent?

Q10) What is the dependent variable in this experiment? Why is this a dependent variable?

Q11) What variables are controlled in this experiment? Why are/is these/this variable control variable(s)?

Q9. The independent variable in this experiment is the fertilizer. It is independent because she manipulating the variable to compare the growth.

Q10. The dependent variable in this experiment is the amount of growth of the corn. It is this because the growth depends on what the scientist did on the corn.

Q11. The variable controlled in this experiment is the amount of sun and water. These two variables never change so this is why it is the control.
