Question

use the following information to answer items 1 through 3. a student conducts an experiment to grow tomato plants and collects the following data.
fertilizer used | height after 60 days (in cm) | number of seeds planted | size of pot (in cm)
fertilizer a | 30.48 | 5 | 15
fertilizer b | 31.75 | 5 | 15
fertilizer c | 35.56 | 5 | 15
match each term with the correct information about the experiment.
type of fertilizer used
height of tomato plant after 60 days
size of pot, number of seeds, amount of water
drag & drop the answer
constants independent variable dependent variable

Explanation:

1. Independent Variable: The independent variable is the factor that is manipulated in an experiment. Here, the "Type of fertilizer used" (Fertilizer A, B, C) is what the student changes to observe its effect, so it's the independent variable.
2. Dependent Variable: The dependent variable is the factor that is measured or observed to see the effect of the independent variable. The "Height of tomato plant after 60 days" depends on the type of fertilizer, so it's the dependent variable.
3. Constants: Constants are factors that are kept the same throughout the experiment to ensure a fair test. "Size of pot, number of seeds, amount of water" (assuming water is constant, and pot size, number of seeds are constant as per the table) are kept constant, so they are constants.

Answer:

• Type of fertilizer used: Independent Variable
• Height of tomato plant after 60 days: Dependent Variable
• Size of pot, number of seeds, amount of water: Constants
