in an experiment testing how different amounts of sunlight affect plant growth, what is the independent variable?
time of day
plant growth
type of plant
amount of sunlight
clear my selection

Explanation:

In an experiment, the independent variable is the one that is manipulated to observe its effect on the dependent variable. Here, the experiment tests how different amounts of sunlight affect plant growth. So the amount of sunlight is the factor being changed (independent variable), while plant growth is the dependent variable (what's measured). Time of day and type of plant are not the manipulated factor here.

Answer:

Amount of sunlight (the option corresponding to "Amount of sunlight")
