Front

What is a control (constant) variable in an experiment?

Back

A control (constant) variable is a factor that remains unchanged throughout an experiment to ensure that the results are due to the independent variable.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is intentionally changed or manipulated in an experiment to observe its effect on the dependent variable.

Front

What is the dependent variable in an experiment?

Back

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

Front

How many variables should be changed in a well-designed controlled experiment?

Back

Only one variable should be changed to ensure that the results are valid and reliable.

Front

What does it mean when a scientific theory is modified?

Back

It means that the theory has been updated or changed based on new evidence or discoveries that challenge previous understandings.

Front

What is the purpose of a control group in an experiment?

Back

The control group serves as a baseline to compare the effects of the independent variable, helping to isolate the results of the experiment.

Front

What is the significance of new evidence in scientific theories?

Back

New evidence can lead to revisions or changes in scientific theories, enhancing our understanding of natural phenomena.

Front

What is the role of observations in scientific experiments?

Back

Observations are critical for collecting data, which helps scientists analyze results and draw conclusions.

Front

What is a hypothesis?

Back

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

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.
