Popplet My breakup with Facebook Two days after I’d made the New Year’s resolution to quit Facebook, I realized how much the site had been messing with my mind. Holding hands with my son, walking down a gritty urban street in downtown Los Angeles, I suddenly stepped out of myself and observed the way my innocent, sun-kissed 6-year-old contrasted with the steely greys of the streetscape around us. I saw the construction, the hipsters strolling with their hip dogs, and thought, “I need to post this.” Not, “I need to take a picture of this,” but that I needed to share this experience with others. The impulse hit me hard and felt incredibly wrong. And not even a week into this experiment, I already felt sunk. The suspicion that Facebook was satisfying a need I didn’t even know I had — training me for a certain kind of behavior — made me wonder if I needed a support group or something. I wasn’t always like this. Of course, he was right. I had to switch roles often on Facebook.

Prehistoric Shark Species Found in Arizona - During the Middle Permian era 270 million years ago, Arizona was home to a diverse shark population. - Numerous new sharks from that period have been discovered, with three now described in detail. - The three sharks ranged from small to large, but all were toothy and ate other sharks. The remains of several new toothy shark species, with at least three dating to 270 million years ago, have been unearthed in Arizona, according to a new study. The research, published in the latest issue of Historical Biology, suggests that Arizona was home to the most diverse collection of sharks in the world during the pre-dinosaur Middle Permian era. NEWS: Shark Paradise Found For now, lead author John-Paul Hodnett described the three mentioned in the latest study: Nanoskalme natans ("swimming dwarf blade") was a small (about 3.2-foot- long) shark with blade-like cutting teeth. Kaibabvenator swiftae ("Swift's Kaibab hunter") was a large (around 19.7 feet ) shark with big serrated cutting teeth.
Questioning – Top Ten Strategies “Learn from yesterday, live for today, hope for tomorrow. The important thing is to not stop questioning.” – Albert Einstein Questioning is the very cornerstone of philosophy and education, ever since Socrates ( in our Western tradition) decided to annoy pretty much everyone by critiquing and harrying people with questions – it has been central to our development of thinking and our capacity to learn. Most research indicates that as much as 80% of classroom questioning is based on low order, factual recall questions. Effective questioning is key because it makes the thinking visible: it identifies prior knowledge; reasoning ability and the specific degree of student understanding – therefore it is the ultimate guide for formative progress. 1. 2. Taken from ‘Mock the Week’, this simple little technique sparks the inquisitiveness within students – just by quickly reversing the standard question and answer dichotomy it can deepen their thinking. 3. 4. 5.

Extinct Giant Whale-Eating Whale Found - Unlike modern sperm whales, this one had teeth in both jaws and might have eaten like killer whales. - The 10-foot sperm whale skull fossil is the largest ever found. - Its main food might have been baleen whales. The massive skull and jaw of a 13-million-year-old sperm whale has been discovered eroding from the windblown sands of a coastal desert of Peru. The extinct cousin of the modern sperm whale is the first fossil to rival modern sperm whales in size -- although this is a very different beast, say whale evolution experts. "We could see it from very far," said paleontologist Olivier Lambert of the Muséum National d'Histoire Naturelle in Paris, France, who led the team which found the fossil. PHOTOS: Mammals of the Sea The giant 3-meter (10-foot) skull of what's been dubbed Leviathan melvillei (in honor of the author of "Moby Dick") was found with teeth in its top and bottom jaws up to 36 centimeters (14 inches) long.

critical-thinking - home Songs of the Deep Few species on Earth communicate as frequently and effectively as human beings, and none so majestically or ubiquitously as whales. Immersed in an environment rich in sound but poor in light, whales and dolphins developed complex communication systems that they use to mate, feed, socialize, and navigate. The "vocabulary" of some types of whales such as the beluga and humpback is expansive, and rivals most non-humans creatures. Others can communicate over vast distances across the abyss. And, while not strictly communication, many dolphin and whale species use advanced echolocation to hunt and navigate. The means and ends of these communications are most astounding to humans perhaps because we are accustomed to viewing communication as a sign of intelligence, and probably most people believe that humans are the only truly intelligent species on this planet. These long-distance communications are carried along a natural underwater network of acoustic waveguides.
