What term describes an event with an unexpected conclusion in science demonstrations?

• A. Discrepant event
• B. Predictable outcome
• C. Routine observation
• D. Controlled experiment

Answer: (A)

Discrepant events are used in science demonstrations to provoke curiosity by presenting a result that does not align with what students expect. The idea is to reveal a phenomenon that challenges intuition, so learners observe carefully, reexamine their assumptions, and generate explanations. The name itself points to a discrepancy between predicted and observed outcomes. The other terms describe things that aren’t surprising, or refer to how a study is designed rather than producing an unexpected conclusion: a predictable outcome is what was anticipated; a routine observation is ordinary; and a controlled experiment is about the method, not the surprising result.
