Plant growth is dependent on the amount of fertilizer applied. That was the hypothesis Mel and Bill decided on for their science project. They planted identical seeds in the same potting mix, in similar pots. Each pot received the same amount of water and all the pots were placed in the same location in the greenhouse. Mel and Bill’s data was summarized after three weeks. What would be an appropriate research question to guide this scientific investigation?

How does location and fertilizer amounts influence plant growth?

Explanation:
Detailed explanation-1: -One possible hypothesis may be that there will be no effect on yield associated with N fertilization. This hypothesis, called the null hypothesis, is evaluated with an experiment to test crop yield response against a range of N rates in a field likely to produce a large response to the addition of N fertilizer.
Detailed explanation-2: -In this experiment, the addition of fertilizer is the independent variable manipulated by the scientist. Plant height is the dependent variable that responds to the change in the independent variable. Each plant is exposed to an equal amount of sunlight, so sunlight is the control variable.
