Question

mr forsman wants to set up an experiment to test which type of fertilizer helps his tomato plants grow tomatoes the quickest. he bought 4 tomato plants in pots (none of the tomato plants have any tomatoes currently) and 3 types of fertilizers (fertilizer a, b, & c). he hypothesizes that fertilizer a will help plants grow ripe tomatoes the fastest. please create an experiment that mr forsman could conduct that would help him test his hypothesis. in your explanation, please make sure to include the following: -what would his control group be? -what would his independent variable be? -what would his dependent variable be?

Explanation:

1. The dependent variable is what is being measured. In this case, it's the rate at which the tomato plants grow ripe tomatoes.
2. The independent variable is what is being changed. Here, it's the type of fertilizer (fertilizer A, B, or C).
3. The control group is a baseline group. For this experiment, it would be tomato plants with no fertilizer.

To create an experiment, Mr. Forsman could divide his tomato plants into 4 groups: one group with no fertilizer (control), and three groups each receiving fertilizer A, B, and C respectively. Keep all other factors like sunlight, water, and pot - size the same for all groups. Then measure and compare the time it takes for the tomatoes to ripen in each group.

Answer:

• Dependent variable: Rate of tomato ripening.
• Independent variable: Type of fertilizer (fertilizer A, B, C).
• Control group: Tomato plants with no fertilizer.
