1. Teacher Guide This lesson is designed to teach kids to ask a critical thinking question that you can’t just put into a search box to solve. To do that, we encourage them with smaller questions that search can help them answer. Make sure that you read the notes for each slide: they not only give you teaching tips but also provide answers and hints so you can help the kids if they are having trouble.

3. There are whales, and then there’s the sperm whale. These squid-eating cetaceans have many adaptations that set them apart from other whales. The tall head isn’t broad, as was often depicted in early illustrations, but rather, wedge-like, with the blowhole skewed a little to the left, like a jaunty hat. Inside that unusual cranium are two chambers, toward the front, both filled with various fats and triglycerides known as spermaceti (hence the name). Studies have found that this medium conducts sound waves with great efficiency, giving the sperm whale the ability to make extremely loud clicking sounds – the loudest sound of any known living animal. Scientists believe this specialized echolocation ability allows the sperm whale to stun its prey with a concentrated burst of sound.
