Answer :
The dependent variable in the given experiment is plant height.
To identify the dependent variable in the given experiment, follow these step-by-step points:
Understand the experiment: The experiment involves keeping bell pepper seedlings at different temperatures for three weeks and recording plant height measurements every two days.
Identify the independent variable: The independent variable in this experiment is the different temperatures at which the bell pepper seedlings are kept. It is deliberately manipulated by the researcher.
Determine the purpose of measurement: The measurements taken every two days serve to observe and track the growth of the bell pepper seedlings.
Define the dependent variable: In this experiment, the dependent variable is the plant height. It is the variable that is measured and expected to change as a result of the different temperatures the seedlings are exposed to.
Relationship to the independent variable: The dependent variable, plant height, is influenced by the independent variable, different temperatures. The purpose of measuring the plant height is to determine how temperature affects the growth of the bell pepper seedlings.
Based on these points, the dependent variable in the experiment is plant height, as it is the variable being measured and expected to be influenced by the different temperatures the seedlings are exposed to.
