Scientific Method Review (9th)

When using the scientific method, what is usually the first step?

• Observing and asking a question

• Forming a hypothesis

• Designing an experiment

• Collecting data

When using the scientific method, once you have asked a question, but before constructing a hypothesis, what should you do?

• Research the question

• Design an experiment

• Collect data

• Organize and analyze data

Which of the following statements are components of a hypothesis statement?

• IF I do/test this...

• THEN this will happen...

• BECAUSE I know this to be true (based on research/observation)...

• All of these answers

When designing an experiment, how do you make sure your data is valid? (Select all that apply...)

• Use repeated trials

• Use many subjects

• Use Wikipedia
