Question

what may be the dependent variable in this experiment?
zero drops of fertilizer
2 drops of fertilizer
4 drops of fertilizer
6 drops of fertilizer
= fertilizer

Explanation:

In an experiment, the dependent variable (DV) depends on the independent variable (here, amount of fertilizer). The experiment involves plants and fertilizer, so the DV is likely a plant - related outcome like plant growth (e.g., height, number of leaves, size of leaves). Since the plants are being watered and given different fertilizer amounts, the growth of the plant (such as its height, leaf count, or overall size) is what's being measured as it depends on the fertilizer (independent variable).

Answer:

Plant growth (e.g., height of the plant, number of leaves, size of the plant, etc.)
