Below are sample questions representative of the exercises included on this worksheet and related 8.01 Scientific Inquiry Cycle skill assessments:

Problem 1Difficulty: Mastery
Scientists studying a new phenomenon notice an unexpected pattern in their data. They propose a new explanation, design a better-controlled experiment, and update their explanation again after the new results.
Which statement best describes this process?
AA single experiment is enough to prove a claim forever.
BScientific work is mostly opinion, so evidence is optional.
CGood science avoids changing explanations once written.
DScientific inquiry is iterative: questions lead to investigations and evidence, and explanations are revised as new data emerge.
Solution & Explanation:D accurately describes the inquiry cycle as an ongoing loop of questioning, testing, analyzing evidence, and revising explanations when new data appear.
Problem 2Difficulty: Mastery
A student builds a computer model of how a flu spreads in a school and predicts the peak will occur in 15 days. Real attendance data show the peak happens in 22 days. "
Which response best applies the inquiry cycle to models and evidence?,A. Declare models useless and stop collecting data. | B. Change the attendance data to match the model. | C. Use the mismatch to revise model parameters (like contact rates or recovery time)

Problem 3Difficulty: Mastery
Several studies on caffeine and plant growth report different results. One study used seedlings, another used mature plants, and soil types differed.
What is the best way to use the scientific inquiry cycle to make progress?
APick the study you like best and ignore the others.
BCompare methods to identify variables that differ, then design a new controlled investigation that tests those variables (plant age, soil type) systematically.
CAssume all studies are wrong because they disagree.
DAverage all numbers without checking how the studies were done.
Solution & Explanation:Disagreement invites deeper inquiry. B uses differences in methods as clues, then proposes a controlled, systematic test to refine explanations with stronger evidence.
