Front

What is an independent variable?

Back

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

Front

What is a dependent variable?

Back

The variable that is measured or observed in an experiment, which is affected by the independent variable.

Front

What is a control group?

Back

A group in an experiment that does not receive the treatment and is used for comparison.

Front

What does it mean to keep everything constant in an experiment?

Back

It means to keep all variables the same except for the independent variable to ensure a fair test.

Front

What is the purpose of a control in an experiment?

Back

To provide a baseline for comparison against the experimental group.

Front

What is the x-axis in a graph?

Back

The horizontal axis, typically representing the independent variable.

Front

What is the y-axis in a graph?

Back

The vertical axis, typically representing the dependent variable.

Front

Why is it important to have a control group in an experiment?

Back

It helps to isolate the effects of the independent variable by providing a standard for comparison.

Front

What is a hypothesis?

Back

A testable prediction about the relationship between the independent and dependent variables.

Front

What is the scientific method?

Back

A systematic process for conducting experiments and making observations to answer questions.
