Question #61205
Answer questions #1-3 based on the following scenario.
Scientists tested the effect of a fertilizer on the growth of plants. They had 2 sets of plants, Group A which gets fertilizer, water and sun and Group B which gets only water and sun (but in equal amounts to Group A).
1. Explain how this scenario is a controlled experiment and identify the manipulated variable.



2. If the scientists only performed 1 experiment but it supported their hypothesis, why can it not be considered a theory?



3. The graph below was created showing the growth of the plant. How would you know that the y-axis is measuring the growth of the plant?
