Scientific Method and Variables

Front

What is the scientific method?

Back

The scientific method is a systematic process used for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. It typically involves making observations, forming a hypothesis, conducting experiments, and drawing conclusions.

What is a variable in an experiment?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types. In experiments, variables are used to test hypotheses.

Front

What is a dependent variable?

Back

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

Front

What is a hypothesis?

Back

A hypothesis is an educated guess or prediction about the relationship between two variables, which can be tested through experimentation.

Front

What is a controlled experiment?

Back

A controlled experiment is a scientific test that is directly manipulated by a scientist, where only one variable is changed at a time while all others are kept constant.

Front

What is the first step of the scientific method?

Back

The first step of the scientific method is to identify a question or problem that needs to be investigated.

Front

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

Back

The control group serves as a baseline that allows scientists to compare the results of the experimental group to see the effect of the independent variable.

Front

What does it mean to analyze data in an experiment?

Back

Analyzing data involves examining and interpreting the results of an experiment to determine whether the hypothesis is supported or refuted.

Front

What is a conclusion in the scientific method?

Back

A conclusion is a summary of the results of an experiment, stating whether the hypothesis was supported or not, and discussing the implications of the findings.
