Science Variables

Front

What is a variable in a scientific experiment?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types in an experiment.

Front

What is an independent variable?

Back

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

Front

What is a dependent variable?

Back

The dependent variable is the variable that is measured and affected in the experiment; it responds to changes in the independent variable.

Front

What is a constant in an experiment?

Back

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

Front

What is a control group?

Back

A control group is a group in an experiment that does not receive the treatment and is used as a benchmark to measure how the other tested subjects do.

Front

How does changing the independent variable affect the dependent variable?

Back

Changing the independent variable can cause changes in the dependent variable, which is what the experiment is measuring.

Front

What is the purpose of a hypothesis in an experiment?

Back

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

Front

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

Back

A control group is important because it allows for comparison against the experimental group to see if the independent variable had an effect.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities (e.g., color, texture), while quantitative data involves numbers and measurements (e.g., height, weight).

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
