Back

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

Front

What does SEP stand for?

Back

SEP stands for Science and Engineering Practices.

Front

What is a hypothesis?

Back

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

What is quantitative observation?

Back

Quantitative observation involves measurements and numerical data, providing exact information.

Front

What is qualitative observation?

Back

Qualitative observation involves descriptions and characteristics that cannot be measured numerically.

Front

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

Back

A control group is used as a standard for comparison to determine the effect of the independent variable.

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.

Front

What is an experiment?

Back

An experiment is a procedure carried out to test a hypothesis by manipulating variables and observing the outcomes.

Front

What is a variable in an experiment?

Back

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