Experimentation Review (Parts of an Experiment)

Front

What are constants in an experiment?

Back

Constants are the factors that remain the same throughout the entire experiment to ensure that the results are due to the independent variable.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or manipulated by the experimenter to observe its effect on the dependent variable.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in response to changes in the independent variable.

Front

What is a control group in an experiment?

Back

A control group is a standard of comparison in an experiment that is not exposed to the independent variable, allowing for a baseline to measure the effects of the independent variable.

Front

What is the purpose of conducting an experiment?

Back

The purpose of conducting an experiment is to test a hypothesis by manipulating one variable and observing the effect on another variable.

Front

How do you identify the independent variable in a given experiment?

Back

The independent variable can be identified as the one that is intentionally changed or varied by the researcher.

Front

What is the role of the dependent variable in an experiment?

Back

The dependent variable is the outcome that is measured to see if it changes as a result of manipulating the independent variable.

Front

Why is it important to have constants in an experiment?

Back

Constants are important because they help ensure that the experiment is fair and that the results are valid, isolating the effect of the independent variable.

Front

What is an example of a control group in an experiment testing plant growth with different colored lights?

Back

An example of a control group would be plants grown under normal white light, without any colored filters.

Front

In an experiment testing different types of cat food, what would be the dependent variable?

Back

The dependent variable would be the amount of food the cat eats.
