Cross-Check Sources

An answer that really matters deserves more than one check — compare it across two or more trusted sources that don't just copy each other, and know what to do when they disagree.

Kavi Cross-Checks the Moon

Kavi is writing a report. She asks a helper, "Who first walked on the Moon?" "Neil Armstrong, in 1969!" it says — fast and sure. "This goes in my report, so one source isn't enough," hoots Kavi. She opens an encyclopedia: Neil Armstrong, 1969. She checks a space-museum website: the same. "Two trusted sources that don't just copy each other — and they agree. Now I really know." Then her friend grins, "I found two websites that agree!" Kavi looks closer — both copied the same blog. "That's really one source twice," she smiles. "A real cross-check needs sources that stand on their own."

A peek inside

My report says the first person to walk on the Moon was Neil Armstrong, in 1969. It really matters — how do I cross-check it?
One source isn't enough for something I'll share. I check an <b>encyclopedia</b> — Neil Armstrong, 1969. Then a <b>space-museum website</b> — the same. The two are trusted and <b>don't copy each other</b>, and they agree, so now I really know.

Questions parents ask

+What does it mean to cross-check sources?

Cross-checking means comparing an important answer across more than one trusted source, instead of relying on a single one. When two or more independent, reliable sources agree, you can trust the answer much more.

+Why isn't one trusted source enough?

Even a careful source can make a mistake. Checking a second, independent trusted source — one that doesn't just copy the first — gives much stronger evidence that the answer is really true.

+What are 'independent' sources?

Independent sources don't just copy one another. An encyclopedia and a museum's own website are independent; two websites that both copied the same blog are really one source twice, so they can repeat the same mistake.

+What do you do when two trusted sources disagree?

Don't just pick the one you like. Find a third trusted source or go to the original, then trust the answer the reliable sources support — and explain how you decided.

+What age is this 'Cross-Check Sources' lesson for?

It is a Stage 6 lesson for roughly ages 11–12 in KAVI Academy's AI-literacy track. It builds on earlier lessons about checking a single trusted source and tracing a claim to its origin.
