Debate: How Can Social Media Help Save More Abandoned Dogs and Cats?

Animals Ethics

One animal shelter is using social media to lead to raise animal adoption rates. Over the course of the last five years, a government-run shelter in Virginia went from euthanizing one-third of all stray animals to a nearly 90% adoption rate. By reaching out to the public for help on social media, the Animal Care and Control department has been able to find more animals homes more quickly. Listen to learn more about this department's innovations and then debate solutions in class on how social media can help save more abandoned dogs and cats.

Why Woolly Mammoths Have Thick Furry Coats

Animals Genetics DNA

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. In this audio story, we hear from a scientist who studied the DNA from the extinct mammoth and compared it to its contemporary descendant. Listen to learn more about what researchers discovered.

How Wind Affects Wildlife

Environment Animals Energy

The Department of Fish and Wildlife wants to find out how bears will react to a new wind project. It will be the first commercial wind project on U.S. Forest Service land and will include 15 turbines.They started tracking bears by using radio collars to see how they move around before the turbines are in place. The collars had many problems, so they started using cameras to track the bears. Now they have data to study bears and wildlife both before and after the wind project begins. Share this story with your students so they can learn more about this wind project in Vermont and its impact on wildlife.

Whale Sounds

Life Science Animals Elementary Sound

Humpback whales sing and continually change their songs. In the 1960’s Navy engineers used underwater microphones to record sounds in the ocean to locate enemy ships. They happened to also record whale sounds. Scientists studied these sounds and discovered that only male humpback whales sing and they gradually modify their songs. The humpback’s songs have patterns and rhythms and are not just random sounds. Listen to hear more about how sound is used to learn about the life of whales.
