**Independent Variable:** The amount of sunlight each tomato plant gets. This is what the student is changing. One plant gets 0 hours, and the others get 1, 3, 5, 7, and 9 hours of sunlight.
**Dependent Variable:** The sweetness of the tomatoes and the number of leaves each plant produces. This is what the student is measuring to see how it is affected by sunlight.
**Controlled Variables:** These are the things the student keeps the same for all the plants. They include:
- The same amount of water given to each plant every day.
- The same type and amount of fertilizer used for all plants.
- The same growing conditions, like temperature and soil type.
- The same kind of tomato plants used in the experiment.
By keeping these controlled variables the same, the student can be sure that any differences in sweetness and leaves are because of the sunlight!
