Scientific Investigation Review Quiz

What is a hypothesis?

• A proposed explanation for a phenomenon or a scientific question that can be tested through experimentation or observation.

• A proven fact that does not require testing

• A conclusion drawn from personal opinion rather than research

• A random guess with no basis in evidence

What are the key components of experimental design?

• Qualitative, quantitative, mixed methods, and case study

• Hypothesis, conclusion, data analysis, and results

• Control group, experimental group, independent variable, dependent variable, and control variables (constants)

• Survey, interview, observation, and questionnaire

What are the different types of variables in an experiment?

• Independent, dependent, and controlled variables (constants)

• Fast, slow, and medium variables

• Hot, cold, and warm variables

• Red, blue, and green variables

Why is it important to draw a conclusion based on the results of an experiment?

• To delay the decision-making process and avoid understanding the results

• To confuse the significance of the results and make random decisions

• To ignore the results and make uninformed decisions

• To understand the significance of the results and make informed decisions.

How does the independent variable differ from the dependent variable in an experiment?

• The independent variable is not important in an experiment

• The dependent variable is manipulated by the experimenter

• The independent variable is the outcome that is measured

• The independent variable is manipulated by the experimenter, while the dependent variable is the outcome that is measured.

What is the role of control variables (constants) in an experiment?

• To confuse the experimenter

• To ensure that the experiment is fair and that the results are valid

• To manipulate the outcome of the experiment

• To make the experiment more complex

What is the purpose of a control group in an experiment?

• To provide a standard for comparison

• To confuse the results of the experiment

• To manipulate the outcome of the experiment

• To make the experiment more complex

Why is it important to repeat an experiment?

• To waste time and resources

• To ensure the results are reliable and not due to chance

• To confuse the results of the experiment

• To make the experiment more complex

Why is it important to have a clear and specific hypothesis?

• To ensure the results are reliable and not due to chance

• To provide a clear direction for the experiment and to make it testable

• To confuse other scientists

• To prove that the phenomenon is already understood
