Snakes! Show your students how applied science works with this PBS NewsHour story on treating snake bites from June 19, 2014. Although snake bites are rarely fatal in the United States, every year about 100,000 people die worldwide after being bitten by venomous snakes.

In this video segment from Nature, we learn that dogs were the first creatures to be domesticated. Ancient people thought of dogs as creatures of magic and as spiritual guardians. Dogs were often sacrificed and buried with people to protect them with their magical powers. In Mexico today, hairless Xolo (SHOW-low) dogs are believed to heal pain. Around the world dogs are useful to people for protection because of their bark, which acts as an alarm and can intimidate strangers. Barking dogs are a stronger deterrent for burglars than a burglar alarm.

In this Nature video, we learn how the Inuits of the Arctic Circle rely on their dogs. Existing on a diet of snow and seal blubber (fat), these dogs pull the sleds of the Inuits and protect them from wild animals. Multiple dogs pull together to maintain the stability of the sled. Sled dogs sometimes run the equivalent of five marathons (5 x 26.2 miles = 131 miles) per day. They will be the first to fall through the ice if there is a crack, but they recover from the cold plunge quickly. The dogs have evolved to master the harsh environment.
