Identifying Variables

Front

What is a dependent variable?

Back

The dependent variable is the outcome or effect that is measured in an experiment. It changes in response to the independent variable.

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

In an experiment, what is a constant?

Back

A constant is a factor that remains the same throughout the experiment to ensure that the results are valid.

Front

What is the purpose of identifying variables in an experiment?

Back

Identifying variables helps to understand the relationship between different factors and how they affect the outcome of the experiment.

Front

Give an example of a dependent variable in a plant growth experiment.

Back

The height of the plant after a certain period of time.

Front

Give an example of an independent variable in a dog walking experiment.

Back

The number of times the dog is taken for a walk each day.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe its effect on the dependent variable.

Front

Why is it important to have constants in an experiment?

Back

Constants ensure that the experiment is fair and that the results are due to the independent variable alone.

Front

What might be a dependent variable in an experiment testing different types of soil on plant growth?

Back

The growth rate or height of the plants.

Front

What is an example of a constant in an experiment measuring how liquid affects plant growth?

Back

The amount of sunlight each plant receives.
