What is the scientific method?

• The scientific method is a set of rules that scientists must follow in order to conduct experiments.

• The scientific method is a process used by scientists to prove their hypotheses.

• The scientific method is a systematic approach used by scientists to investigate and understand the natural world.

• The scientific method is a step-by-step procedure used by scientists to solve problems.

What is an independent variable?

• A variable that is measured or observed in an experiment.

• A variable that is manipulated or controlled by the researcher in an experiment.

• A variable that is not relevant to the experiment.

• A variable that is determined by chance in an experiment.

What is a dependent variable?

• A dependent variable is the variable that is manipulated or changed in an experiment or study.

• A dependent variable is the variable that is controlled by the researcher in an experiment or study.

• A dependent variable is the variable that is not affected by the independent variable in an experiment or study.

• A dependent variable is the variable being measured or observed in an experiment or study.

What is a control group?

• A control group is a group in an experiment that does not receive the experimental treatment or intervention.

• A control group is a group in an experiment that receives a different type of experimental treatment or intervention.

• A control group is a group in an experiment that receives a higher dosage of the experimental treatment or intervention.

• A control group is a group in an experiment that receives the same experimental treatment or intervention multiple times.

• A group that receives a placebo instead of the treatment being tested.

• A group that does not receive any treatment or intervention.

What is data?

• A set of instructions

• A collection of facts, statistics, or information.

• A sequence of events

• A group of numbers

Why is it important to repeat experiments?

• To ensure reliability and validity of results, identify errors, and establish reproducibility.

• To make the experiment more complicated

• To confuse researchers

• To waste time and resources
