What is the goal of a scientific method?

• To systematically investigate and answer scientific questions

• To memorize scientific facts without understanding

• To ignore evidence and rely on opinions

• To avoid making observations and experiments

Why might scientific methods vary from case to case?

• Because each question and researcher’s approach can be different

• Because the laws of science change

• Because experiments are always the same

• Because only one method is allowed

Which step comes immediately after "Ask question" in the scientific method flowchart shown?

• Make observation

• Develop hypothesis

• Test hypothesis with an experiment

• Draw a conclusion

Why might the order of steps in the scientific method vary?

• Because some steps are not important

• Because different experiments may require different approaches

• Because the scientific method is only used in chemistry

• Because the steps must always be followed in the same order

According to the scientific method, what should you do after analyzing data and drawing conclusions?

• Make an observation

• Ask a question

• Decide if the hypothesis is supported or not supported

• Develop a hypothesis

Why might the order of steps in the scientific method vary?

• Because some steps are unnecessary

• Because different experiments require different approaches

• Because the scientific method is not a real process

• Because scientists do not follow any order

A scientist tests a hypothesis with a single experiment, analyzes the data, and finds that the hypothesis is supported. What is the next logical step?

• Revise the hypothesis

• Develop theory

• Make a new observation

• Test hypothesis with further experiments

Why do scientific investigations often begin with making observations?

• Because observations provide information through senses that can lead to questions and further investigation.

• Because observations are always correct.

• Because observations are the final step in the scientific method.

• Because observations are not important in science.

What is a variable in an experiment?

• Any factor that can change

• The result of an experiment

• The equipment used in an experiment

• The person conducting the experiment

What is the role of the responding variable in an experiment?

• It is kept constant

• It causes a change

• It changes in response to the manipulated variable

• It is not measured
