Evaluate a claim by checking its source and looking for agreement across multiple reliable sources, and separate fact from opinion.
Before believing a surprising claim, ask three questions: WHO said this -- an expert, or just anyone? WHEN was it said -- recent, or possibly outdated? Does more than one reliable source agree? Also separate a fact (something that can be proven true or false) from an opinion (a belief or feeling that cannot be proven).
Try fact-checking two popular myths. Myth 1: "Bats are blind." Fact-check: most species of bats can see just fine; many also use echolocation, bouncing sound off objects, to navigate in total darkness. Myth 2: "The Great Wall of China is the only human-made object visible from space." Fact-check: astronauts have reported the Great Wall is actually hard to see with the naked eye from orbit, while cities, airports, and other structures can be more visible.
Mastery looks like: They can evaluate a claim by checking its source and looking for agreement across multiple reliable sources, and can separate fact from opinion.
Common stumbles: Believing a claim just because it sounds confident or is repeated often; confusing a strongly worded opinion with a checkable fact.
