Scientific Method Vocabulary

What is the dependent variable in an experiment?

• The effect or result of the experiment that you have no control over
• The variable that changes as a result of the independent variable manipulation
• The variable that stands alone and isn't changed by other variables
• The outcome you're interested in measuring

What is an observation?

• A statement about a phenomena that always happens under certain conditions
• A statement that explains why a phenomenon happens
• Using your senses to collect data
• A way to represent something in science

Which of the following is an example of quantitative data?

• The color of a flower
• The shape of an object
• The temperature of a substance
• How something looks

What is the difference between a theory and a law?

• A theory is always supported by evidence, while a law is not
• A theory is based on empirical data, while a law is not
• A theory explains why a phenomenon happens, while a law describes what you can see happening
• They are the same

What is a hypothesis?

• A statement about a phenomena that always happens under certain conditions
• An if-then statement based on a problem you want to solve
• A statement that explains why a phenomenon happens
• A way to represent something in science

What is the purpose of collecting data in an experiment?

• To represent something in science
• To explain why a phenomenon happens
• To establish facts and test hypotheses
• To describe what you can see happening

What is the independent variable in an experiment?

• The variable that stands alone and isn't changed by other variables
• The variable that changes as a result of the independent variable manipulation
• The outcome you're interested in measuring
• The effect or result of the experiment that you have no control over

What are the characteristics of a hypothesis?

• An educated guess
• A proven theory
• A statement of fact
• A scientific law

What are the steps of the scientific method?

• Conclusion, Experiment, Problem, Hypothesis, Observation
• Dependent, Responding, Y-Axis
• Manipulated, Independent, X-Axis
• Problem, Hypothesis, Experiment, Observation, Conclusion

Which of the following is an example of a scientific model?

• A statement about a phenomena that always happens under certain conditions
• A process in which measurements are used to verify a hypothesis
• A math equation
• Using your senses to collect data
