This is done after you research
What is make a hypothesis
This is the variable that a scientisit observes and measures
What is the Dependent Varieable
What effect does light have on plant growth?

If a plant receives adequate light, then the plant will grow well.
If Miracle Grow is used, then plants will grow bigger.
IV = Miracle Grow

If students get 8 or more hours of sleep, then they will get better grades.
