Scientific Method Concepts and Procedures

Which of the following is the correct order of the first three steps in the scientific method?

• Ask a Question, Construct a Hypothesis, Do Background Research

• Do Background Research, Ask a Question, Construct a Hypothesis

• Ask a Question, Do Background Research, Construct a Hypothesis

• Construct a Hypothesis, Ask a Question, Do Background Research

What characteristic defines a scientific question as "testable"?

• It can be answered by looking up a recipe or existing information.

• It can be answered by conducting an experiment.

• It starts with "Who," "What," "When," "Where," "Why," or "How."

• It is a general question about a broad topic.

What is a primary purpose of conducting background research in the scientific method?

• To immediately form a conclusion about the experiment.

• To find out what data to collect and how to set up the experiment.

• To skip the step of asking a question.

• To prove the hypothesis is correct before experimenting.

A hypothesis is an educated guess that always includes a prediction. What is the common structure for this prediction?

• "What if [this happens]?"

• "If [I do this], then [this] will happen."

• "Why does [this occur]?"

• "How can I make [this]?"

What is the primary characteristic of a dependent variable in an experiment?

• It is intentionally changed by the experimenter.

• It is kept constant throughout the experiment.

• It is the factor that is measured or observed.

• It influences the independent variable.

What is the initial step when setting up the popping boba experiment?

• Measuring the diameter and height of boba balls.

• Choosing the liquid or food to be tested.

• Making several popping boba balls.

• Recording observations in a lab notebook.

If an experimental procedure is not yielding expected results, what is the recommended course of action?

• Immediately conclude that the hypothesis is incorrect.

• Troubleshoot the procedure and restart the experiment.

• Change the independent variable without altering the procedure.

• Discard all collected data and begin a new experiment from scratch.

When creating a graph to display experimental results, where are the independent and dependent variables typically placed?

• Independent variable on the Y-axis, Dependent variable on the X-axis.

• Both independent and dependent variables on the X-axis.

• Independent variable on the X-axis, Dependent variable on the Y-axis.

• Both independent and dependent variables on the Y-axis.
