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 determine their effects on the outcome.

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 manipulated 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 the first step in the scientific method?

Back

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

Front

What is a control in an experiment?

Back

A control is a standard against which the results of an experiment are compared. It is the part of the experiment that is kept constant.

Front

Why is it important to have a control group?

Back

A control group is important because it helps to isolate the effects of the independent variable by providing a baseline for comparison.

Front

What does it mean to analyze data?

Back

Analyzing data involves examining and interpreting the results of an experiment to draw conclusions and determine whether the hypothesis was supported.

Front

What is a conclusion in scientific research?

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.
