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.

In recent years, we've seen an increase in the intensity of tropical storms and hurricanes due to global warming. But how and why do hurricanes form? Sigrid provides a basic explanation of this phenomenon.

We continue to explore the phenomenon of hurricanes. Why are they so dangerous? And do they serve any purpose?

Columbus Day has always been a controversial holiday in the United States. In this video, Sigrid goes back in time to get some historical background, which sheds a new light on its significance.

Most Americans don't realize how Columbus Day came to be a national holiday, but it actually doesn't have that much to do with Christopher Columbus, and we might even recognize a connection to present-day events.

Every day, we get information from lots of different sources. But how do we know what is true and what is "fake news?" In this 3-part series we explore different kinds of information and misinformation.

What's the difference between disinformation and misinformation? And what about misleading information? Find out in this video.

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?

Brothers Dudley and Chris had the honor of being part of the first ever Jamaican bobsled team, competing at the nineteen eighty-eight Winter Olympics. We hear the true story of how this unlikely team came into existence, and how Chris went from being a spectator to an Olympic competitor with less than a week’s training.

Decades later, the events of the nineteen eighty-eight Winter Olympics seem harder and harder to believe, even to the men at the heart of the original Jamaican Bobsled team. But it really did happen, and the proof is in the strong sporting and commercial legacy they leave for the next generations.
