Scientific Method and Variables

Front

What is the Scientific Method?

Back

The Scientific Method is a systematic process used for scientific investigation, which includes making observations, forming a hypothesis, conducting experiments, analyzing data, and drawing conclusions.

What is a hypothesis?

Back

A hypothesis is a testable statement that predicts the relationship between variables, often formatted as an 'If...then...' statement.

What is a dependent variable?

Back

The dependent variable is the variable that is measured or observed in an experiment; it is affected by changes in the independent variable.

Front

What is an independent variable?

Back

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

Front

What is a control variable?

Back

Control variables are factors that are kept constant throughout an experiment to ensure that the results are due to the independent variable.

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 validate the results of the experiment.

Front

What does it mean for a hypothesis to be testable?

Back

A hypothesis is testable if it can be supported or refuted through experimentation and observation.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities (e.g., color, texture), while quantitative data involves numerical measurements (e.g., height, weight).

Front

Why is it important to repeat experiments?

Back

Repeating experiments is important to verify results, ensure reliability, and identify any errors or anomalies in the data.

Front

What is an experiment?

Back

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