Transcript How have humans mimicked the echolocation abilities of animals

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.

CCSS.ELA-Literacy.RI.7.3Analyze the interactions between individuals, events, and ideas in a text (e.g., how ideas influence individuals or events, or how individuals influence
ideas or events).
CCSS.ELA-Literacy.RI.7.4Determine the meaning of words and phrases as they are used in a text, including figurative, connotative, and technical meanings; analyze the impact

How have humans mimicked the echolocation
abilities of animals like the sperm whale?
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.
