Teachable Moment from IRIS - Magnitude 7.8 New Zealand

IRIS

November 13, 2016  --  IRIS does an excellent job collecting and preparing resources we can use in our classrooms on recent, significant earthquakes. Check out their PowerPoint, visualizations and animations on a magnitude 7.8 earthquake that hit the east coast of New Zealand’s South Island just before midnight local time Sunday, triggering multiple aftershocks and tsunami waves. The earthquake struck about 93 km (58 miles) north of Christchurch at a depth of 23 km (14 miles). Two people are reported dead, and the extent of the property damage is still unknown.

EARTH Magazine: When Earth Hit the Reset Button on Life

EARTH Magazine

From EARTH Magazine, November 3, 2016  --  The Permian-Triassic extinction event wiped out 96% of all marine life and at least 75% of terrestrial life. It is the largest of the "Big Five" extinction events in Earth history, and it defined the boundary between the Paleozoic and the Mesozoic geologic eras. EARTH Magazine explores new research on the "P-T" mass extinction to look at what caused it, and how it can inform our understanding of today's ongoing extinction event. 

EARTH Magazine: Humans, Megafauna Coexisted in Patagonia before Extinction

EARTH Magazine

From EARTH Magazine, October 12, 2016  --  As we celebrate National Fossil Day, EARTH Magazine brings you a story set in Pleistocene South America, where the climate was warming following an ice age. At this time, Patagonia was home to large megafauna species like giant sloths and saber-toothed cats. There was also a new predator on the block: humans. At some point as the climate warmed and human settlers began hunting, the megafauna living in Patagonia and Tierra del Fuego went extinct. 

Listenwise: Oldest Human Fossil Could Be Missing Link in Human Evolution

Listenwise

From Listenwise  --  The earliest known fossil that lead to humans was recently discovered in Ethiopia. Scientists have uncovered a lower jaw with five teeth. The jaw is estimated at about 2.8 million years old, and is nearly half a million years older than the previous record for a human-related fossil. This bone could help explain a branch in the human family tree. Listen to the story to find out how this fossil could fill a gap in the history of human evolution.

Listenwise: 200 Year Old Sharks

Listenwise

From Listenwise, September 22, 2016  --  Sharks can live to be over two hundred years old, and recently a Greenland shark was found who may have lived up to 512 years. These sharks are the longest living vertebrates known to exist. They can be found swimming in the Arctic seas, where researchers are spending time studying the old creatures. Listen to the story to hear more about this fascinating species.

Listenwise: Why Woolly Mammoths Have Thick Furry Coats

Listenwise

From Listenwise  --  Woolly mammoths were large, elephant-like creatures that lived tens of thousands of years ago, during the last great ice age. The thick, furry coat is one of several traits that gave woolly mammoths an advantage in a very cold environment. Today, the closest biological relative is the Asian elephant, which prefers warmer climates. Scientists were curious about the genetic variations between the woolly mammoth and the Asian elephant and what might account for the differences between the two species.
