A surprising fact needs more than confidence
A student says that a particular material always conducts heat faster because a video demonstrated it once. The gold standard of scientific claim verification asks whether the observation, method and explanation justify the claim.
State the claim precisely
Words such as always, never and causes carry strong implications. Clarify the conditions before seeking evidence.
Trace the evidence
Identify the source, method, measurements and comparison. A polished demonstration is not automatically a controlled experiment.
Test competing explanations
Temperature, material thickness, contact and measurement methods may affect a heat experiment. Ask what else could produce the observation.
Distinguish evidence quality
Anecdotes, repeated observations and controlled studies have different strengths and limitations. Teach students to judge evidence in context.
Communicate uncertainty
When evidence is incomplete, a qualified conclusion is more scientific than a confident guess.
Break-test: an authoritative source is corrected
Can students update their conclusion without treating correction as failure?
