Scientific Method and Experimentation Quiz

A scientist notices that a plant in a dark room is not growing as fast as a plant near a window. She thinks the amount of light affects plant growth. This is an example of a(n):

• Conclusion

• Experiment

• Observation

• Hypothesis

After making an observation, the next step in the scientific method is to:

• Formulate a hypothesis

• Analyze data

• Draw a conclusion

• Conduct an experiment

A testable explanation for an observation is called a(n):

• Law

• Theory

• Conclusion

• Hypothesis

Which of the following describes the correct order of the scientific method steps?

• Question, Experiment, Hypothesis, Conclusion, Analyze Data

• Observation, Question, Hypothesis, Experiment, Analyze Data, Conclusion

• Hypothesis, Experiment, Conclusion, Analyze Data, Question

• Conclusion, Question, Observation, Experiment, Hypothesis

After an experiment, a scientist looks at the results to see if the data supports the hypothesis. This step is called:

• Forming a question

• Drawing a conclusion

• Analyzing data

• Making a prediction

A theory is different from a hypothesis because a theory:

• Is a random guess

• Has been repeatedly tested and is supported by a large body of evidence

• Is not based on observations

• Can never be changed or disproven
