Nature of Science and Investigations

What are constants in an experiment?

• Variables that change during the experiment

• The things that stay the same in an experiment, like the number of marbles or the type of liquid used.

• The final results of the experiment

• The equipment used to conduct the experiment.

What are variables in an experiment?

• Variables are the parts of an experiment that can change, like the type of ball used.

• Variables are the fixed elements that do not change during an experiment.

• Variables are the results obtained from an experiment.

• Variables are the tools used to conduct an experiment.

What is a variable that stays the same called?

• A variable that changes

• A constant

• A parameter

• A coefficient

What is the scientific method?

• A step-by-step process used by scientists to conduct experiments and answer questions.

• A theory that explains how scientific knowledge is developed.

• A set of rules that scientists must follow when conducting research.

• A method of teaching science in schools.

What is the purpose of a control in an experiment?

• To ensure the experiment is conducted safely.

• To compare with the experimental group to see if the independent variable had an effect.

• To increase the sample size of the experiment.

• To eliminate all variables in the experiment.

What is the independent variable?

• The part of the experiment that you change to see how it affects something else.

• The part of the experiment that remains constant throughout the study.

• The outcome that is measured in response to changes in the independent variable.

• The variable that is manipulated to observe its effect on the dependent variable.

What is a scientific question?

• A question that can be answered through observation and experimentation.

• A question that has no definitive answer.

• A question that is based on personal opinion.

• A question that is only theoretical and cannot be tested.

What is the dependent variable?

• The part of the experiment that you measure or observe, which changes in response to the independent variable.

• The variable that is manipulated by the experimenter.

• The constant factor that remains unchanged throughout the experiment.

• The initial condition that is set before the experiment begins.

What is an experiment?

• A test that scientists do to learn more about something.

• A method of cooking food.

• A type of scientific theory.

• A way to measure time.

Why is it important to have a fair test?

• It ensures that the results are accurate and not influenced by unfair changes.

• It makes the experiment more complicated and difficult to understand.

• It allows for more variables to be tested at once.

• It guarantees that all participants will succeed.
