Other: How does the temperature at which plants are grown affect plant growth?

Explanation:

The only variable in the table that isn't a constant is the temperature at which the plants were grown. This means that the scientists planted the groups of seedlings in rooms with different temperatures. The scientists then recorded the amount of new leaves the plants had per week to see if the temperature of the room had an effect on plant growth.
