G7 MYP Science Crit B Rubric

What is the main goal of the scientific method?

• To allow scientists to make precise forecasts

• To aid scientists in formulating theories

• To steer scientists in their studies and experiments

• To offer a systematic procedure for scientists to explore natural events, make observations, establish hypotheses, carry out experiments, scrutinize data, and reach conclusions.

What is the primary purpose of a hypothesis in a scientific experiment?

• A hypothesis is used to confirm personal beliefs without any testing.

• A hypothesis is a random assumption that does not need any evidence.

• A hypothesis is a tentative explanation or prediction that can be tested through scientific methods.

• A hypothesis is a conclusion based on personal opinion, not on scientific research.

What is an independent variable in an experiment?

• A variable that is measured or observed in an experiment.

• A variable that is manipulated or controlled by the experimenter.

• A variable that is randomly assigned to participants.

• A variable that is not affected by other variables.

What is a dependent variable?

• A dependent variable is the outcome or response variable that is affected by the independent variable.

• A dependent variable is a variable that is manipulated by the researcher to observe its effect on the independent variable.

• A dependent variable is a variable that is not influenced by any other variables.

• A dependent variable is a variable that is affected by the independent variable.

What is the purpose of keeping certain variables constant in an experiment?

• They are the variables that are adjusted to see the effect on the outcome

• They are the variables that are observed as a result of the experiment

• They are the variables that are maintained the same to ensure the experiment is fair

• They are the variables that are chosen randomly for the experiment

Which of the following is an example of an independent variable?

• The outcome of the experiment based on different conditions

• The units used to measure the dependent variable

• The temperature at which the experiment is conducted

• The number of trials conducted in the experiment

Why is it important to have a control group in an experiment?

• To change the dependent variable

• To observe the independent variable

• To ensure all variables are manipulated except the dependent variable

• To provide a standard of comparison for the experimental group

What is the function of the independent variable in a scientific experiment?

• It is the variable that is manipulated

• It is the variable that is measured

• It is the variable that is kept constant

• It is the variable that is not used
