The Pressure experiement intro to variables

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or manipulated by the experimenter.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment.

Front

What are constants in an experiment?

Back

Constants are the parts of the experiment that remain the same throughout to ensure a fair test.

Front

How many independent variables can be tested in a controlled experiment?

Back

Only one independent variable can be tested at a time in a controlled experiment.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the outcome of an experiment.

Front

What is the purpose of an experiment?

Back

The purpose of an experiment is to test a hypothesis and determine the relationship between variables.

Front

What does it mean to control variables in an experiment?

Back

Controlling variables means keeping all factors the same except for the independent variable to ensure valid results.

Front

What is an example of an independent variable?

Back

In an experiment testing plant growth, the amount of sunlight is the independent variable.

Front

What is an example of a dependent variable?

Back

In an experiment testing plant growth, the height of the plants is the dependent variable.

Front

Why is it important to have constants in an experiment?

Back

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