Variables in Science Experiments: Practice!

Front

What is a dependent variable in a scientific experiment?

Back

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

What is an independent variable in a scientific experiment?

Back

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

Front

What is a controlled variable?

Back

A controlled variable is a factor that is kept constant throughout an experiment to ensure a fair test.

Front

What is a control group?

Back

The control group is the group in an experiment that does not receive the experimental treatment and is used as a baseline for comparison.

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 designed to measure.

Front

What is the purpose of conducting a scientific experiment?

Back

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

Front

What is the significance of replicating experiments?

Back

Replicating experiments is important to verify results and ensure that findings are reliable and not due to chance.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between two or more variables.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.

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.
