Let's find out more about an American activity aimed at school kids: the spelling bee. What is it and how does it work?

Sigrid talks about "The Elementary Spelling Book" by Noah Webster, which was the basis for the American English dictionary and a big part of the development of spelling bees in the United States.

Sigrid explains how a spelling bee normally proceeds. There are fixed rules and there are options.

Audio and video sources can be factual, and can be used as evidence, but they can both be doctored, too. When we don't have the facts, we might have hearsay, but can we trust it?
