What is a procedure?

• Step by step instructions

• Safety rules

• What stays the same in an experiment

• A prediction

What is the main reason scientists have constants?

• So scientists know their results came only from the independent variable and nothing else

• So scientists stay safe

• So scientists can record data easier

• So the experiment is clear and easy to understand

Which best describes the purpose of a control sample?

• to compare its results to those of a well-known scientist

• to have more qualitative data to analyze at the end of the experiment

In an investigation that uses the scientific method, which step immediately follows forming/making a hypothesis?

• test your hypothesis

• summarizing the results

• making observations

• asking a question

When we test our hypothesis, there are two types of variables. What are they?

• Independent and controlled variable

• dependent and controlled variable

• independent and dependent variable

• none of the above

Constants are factors in an experiment that stay the same. True or False?

• True

• False

What should an experimenter do after analyzing data?

• carry out the experiment

• draw conclusions
