What is a variable in the context of scientific experiments?

Multiple Choice

Which of the following are the two parts of a testable question?

• An independent variable and a dependent variable

• A hypothesis and a conclusion

• A question and an answer

• A cause and a reason

Multiple Choice

Which statement about independent variables is correct?

• They are changed by the scientist in an experiment.

• They are the results measured in an experiment.

• They should never be changed in an experiment.

• They are always the same in every experiment.

Multiple Select

Select all statements that correctly describe a dependent variable.

• It is measured in the experiment

• It is changed by the experimenter

• It responds to changes in the independent variable

• It is always a constant

Multiple Choice

Which of the following best describes a dependent variable in an experiment?

• The variable that is being measured

• The variable that is changed on purpose

• A constant in the experiment

• The equipment used in the experiment

Multiple Choice

What is the purpose of using testable question formats in scientific experiments?

• To ensure questions can be answered through investigation

• To make experiments more complicated

• To avoid measuring variables

• To focus only on independent variables
