In the past two weeks, students across the nation explored whether or not it is it ethical to kill the more aggressive barred owl to save the spotted owl in our #DoNowPredator post. We asked students Should we kill one species to save another? Why or why not?
Each year, tens of thousands of elephants are being slaughtered due to illegal poaching. Poachers kill elephants for their precious ivory tusks, which are now valued even higher than gold. This past March, over 60 scientists from around the world published a paper titled Devastating Decline of Forest Elephants in Central Africa, which portrays a bleak future for African elephants as a result of this poaching. According to the study, in just nine years the African elephant population has decreased by 62 percent, and African elephants have lost 30 percent of their geographical range. If the current rate of poaching continues, elephants could face extinction in as early as 10 years.
In recent years, scientists have discovered carcasses of frozen woolly mammoths with intact tissues and preserved DNA. With this DNA, and that from other extinct animals, researchers are trying to actually clone the extinct animals and bring them back to life. Current technologies are on the verge of making this possible. So far, the closest we’ve come is to de-extincting the passenger pigeon, thanks to frozen DNA samples and the DNA of its closest relative, the band tailed pigeon.

Teaching about cells can be a bit abstract. Often, classroom microscopes are not capable of illuminating tiny cells and structures and textbook images never quite do the amazing cell justice. Current media resources however, can be just the thing to engage students in this microscopic world! In the Cellular Structure and Function activity from PBS […]
