Front

What is an observation in science?

Back

An observation is a statement made based on what one sees, hears, or experiences.

Front

What is an independent variable?

Back

The independent variable is the variable that is manipulated or controlled by the researcher in an experiment.

Front

What is a qualitative observation?

Back

A qualitative observation describes characteristics or qualities, such as color or texture, rather than numerical measurements.

Front

What is another term for the independent variable?

Back

The independent variable is also known as the manipulated variable.

Front

What is a dependent variable?

Back

The dependent variable is the variable that is measured in an experiment to see how it is affected by changes in the independent variable.

Front

What is the purpose of a control in an experiment?

Back

A control is used to provide a standard for comparison and to ensure that the results are due to the independent variable.

Front

What is the difference between qualitative and quantitative observations?

Back

Qualitative observations describe qualities (e.g., color, texture), while quantitative observations involve numerical measurements (e.g., weight, height).

Front

What is a hypothesis?

Back

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

Front

Why are constants important in scientific experiments?

Back

Constants are important because they help ensure that the results of an experiment are valid and reliable.
