Mrs. Hendren has decided that she would like to grow some tomatoes and wants to know how much light is the best amount, so she plants tomato seeds in 4 different pots and leaves one pot in the dark, she gives 6 hours of light a day to the second, eight hours of light a day to the third, and ten hours of light a day to the fourth. After 3 months she measures the size of the tomatoes grown. What is the independent variable?

The correct answer is - the amount of the light received by pots.

Explanation:

An Independent variable is a type of variable which is a change or manipulated in aspecific research or study to find the response of the dependent variable.

In this study, to find the effect of the light on the plant Mrs. Hendren uses the time period of light received by the pots of the plant in order to see the effect on the plant. So the variable that is manipulated is the amount of the light received by the pots.
