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

Front

What is a control group in an experiment?

Back

Back

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

What does CER stand for in scientific reasoning?

Back

CER stands for Claim, Evidence, and Reasoning.

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 the independent variable.

Front

What is the significance of replicating experiments?

Back

Replicating experiments is important to verify results and ensure reliability and validity of findings.

Front

What is the purpose of a graph in scientific data presentation?

Back

Graphs visually represent data, making it easier to identify trends, patterns, and relationships.

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 a variable in the context of an experiment?

Back

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