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. chart: fertilizer used, height after 60 days (in cm), number of seeds planted, size of pot (in cm); rows: 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. boxes: type of fertilizer used, height of tomato plant after 60 days, size of pot, number of seeds, amount of water drag & drop the answer options: constants, independent variable, dependent variable

Explanation:

• Type of fertilizer used: The independent variable is the factor that is manipulated in an experiment. Here, the type of fertilizer (A, B, C) is what the student changes to observe its effect, so it's the independent variable.
• Height of tomato plant after 60 days: The dependent variable is the outcome that depends on the independent variable. The height of the plant depends on the type of fertilizer used, so this is the dependent variable.
• Size of pot, number of seeds, amount of water: Constants are factors that are kept the same throughout the experiment to ensure a fair test. In this experiment, the size of the pot, number of seeds, and (presumably) amount of water are kept constant (size of pot is 15 cm, number of seeds is 5 for all), so these 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
