Scientific Process

Front

What is the scientific process?

Back

The scientific process is a systematic method used to investigate phenomena, acquire new knowledge, or correct and integrate previous knowledge. It typically involves making observations, forming a hypothesis, conducting experiments, analyzing data, and drawing conclusions.

What is an independent variable?

Back

The independent variable is the factor in an experiment that is deliberately changed or manipulated by the scientist to observe its effect on the dependent variable.

Front

What is a dependent variable?

Back

The dependent variable is the factor in an experiment that is measured or observed to see how it is affected by changes in the independent variable.

Front

What are constants in an experiment?

Back

Constants are the factors that remain the same throughout an experiment to ensure that the results are valid and reliable.

Front

What is a control group?

Back

A control group is a group in an experiment that does not receive the treatment or independent variable, serving as a benchmark to measure how the other tested subjects do.

Front

Why is it important for scientific questions to be measurable?

Back

Scientific questions must be measurable to allow for objective analysis and to ensure that the results can be quantified and compared.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between the independent and dependent variables in an experiment.

Front

What is the purpose of conducting experiments?

Back

The purpose of conducting experiments is to test hypotheses, gather data, and draw conclusions about scientific questions.

Front

What is data in scientific research?

Back

Data refers to the information collected during an experiment, which can be quantitative (numerical) or qualitative (descriptive) and is used to support or refute a hypothesis.

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).
