Taking the plunge, one lesson at a time

What can a 28-inch-tall bird teach us about life? Quite a lot. On World Teachers' Day, the Adélie penguin offers a lesson plan packed with resourcefulness, resilience, and a little mischief. Found along the Antarctic coast, the species was named after Adèle, the wife of French explorer Jules Dumont d'Urville, during the expedition that encountered the penguins in 1840.
