Another great year at Science NetLinks is coming to a close! We host thousands of online resources and are constantly adding more. Take a look at the ten most popular Science Update podcasts of 2014 on Science NetLinks:
- Big Heads (Grades 6–12): If somebody is really smart, other people might say: "She's got a really big brain." But when it comes to brains, does size really matter? In this Science Update, you'll hear the complicated answer to that simple question.
- Fever Chill (Grades 6–12): It's cold and flu season, which means you might have recently experienced a case of the chills. In this Science Update, you'll find out why that happens.
- Tilted Earth (Grades 6–12): The fact that the earth is tilted on its axis is what's responsible for giving us different seasons. And it's why the southern hemisphere is getting ready for winter at the same time the northern hemisphere is heading into summer. In this Science Update, you'll hear how that tilt got knocked into place.
- Body Temperature (Grades 6–12): Even a 90-degree summer day is cooler than your body temperature. So why does it feel so warm? You'll find out in this Science Update.
- Germy Surfaces (Grades 6–12): If your brother or sister gets a cold, there’s a good chance that you’ll pick up the same bug—either directly or from something he or she touched or sneezed on. In this Science Update, you’ll find out how long a germ can hang around and wait for its next victim.
- Squirrel Hoarding (Grades 6–12): The gray squirrels that you see in city parks and around neighborhoods are actually forest dwellers. But many of their natural, wooded habitats have been converted into farms, so they've sought refuge in places where they don't have too many predators—like in your backyard. In this Science Update, you'll learn how the loss of gray squirrels is affecting the forest.
- Modern Leeching (Grades 6–12): In the 1800's, leeches used to be the state-of-the-art medicine. But even today, their blood-sucking abilities are still in demand by doctors. You'll hear some reasons why in this Science Update.
- Zapping Fish (Grades 6–12): Spring rains will soon be falling, and warm temperatures will bring the return of thunderstorms. A caller to our 1-800-WHY-ISIT line notes that while most people know enough to leave the water during a lightning storm, most fish continue swimming recklessly. His question is: Why don't they all get zapped?
- Skunk Removal (Grades 6–12): The spray of a skunk is not only incredibly stinky—it's also notoriously difficult to get rid of. An old folk remedy is to bathe in tomato juice, but tests show that only masks the odor. In this Science Update, you'll hear about a better way to neutralize the stink.
- Cold Car Start (Grades 6–12): In places where it gets below freezing in the wintertime, weather reports always include both the air temperature and the wind chill—that is, how cold it feels with the wind blowing. Wind makes the temperature feel colder because it carries heat away from our bodies. In this Science Update, you'll hear how the wind affects car engines in a similar way.
