From EARTH Magazine, 10/28/2015 -- In a Utah cave, paleontologists are exploring the fossil record preserved in owl pellets since the Pleistocene glaciation. The fossils in the pellets are giving the scientists a glimpse of how the ecosystems have changed over time both from natural variation and more recent changes brought on by human settlement.

10/26/2015 -- IRIS does an excellent job collecting and preparing resources we can use in our classrooms on recent, significant earthquakes. Check out their PowerPoint, visualizations and animations on the magnitude 7.5 earthquake that occurred in the Hindu Kush mountains, in the sparsely populated province of Badakhshan, Afghanistan which borders Pakistan, Tajikistan and China.

From EARTH Magazine, 10/21/2015 -- What's the origin of the smartphone you're holding or the tablet from which you are reading this? They're made from minerals such as tin, tantalum and tungsten - minerals that aren't found in many places in the world. One place they are found in relative abundance is the Democratic Republic of the Congo (DRC), where these minerals have been fueling militias in an ongoing war for the last 25 years.

From EARTH Magazine, 10/13/2015 -- Typically, mountains get steeper with increasing altitude. However, during the Pleistocene, a geologic epoch with extensive glaciation, the tops of some mountains, like the Alps, were scoured away. This left mountains that were steeper at a lower elevation than they were at a higher elevation.
New software is providing data for emissions reduction in very specific areas, like your neighborhood. Listen to understand emissions at the local level and discuss how students can calculate their carbon footprint.

September 22, 2015 -- A new species that tells us something about humans origins was recently discovered deep inside a cave in South Africa. This discovery is a mystery in many ways. How did the bones get there? How old are the fossils? What is the significance of discovering them? The bones are so deep inside the cave they were almost inaccessible. The scientist who discovered them hired thin, non-claustrophobic scientists to descend a steep cliff and then climb through a 7-inch wide crack in a cave to collect over 1,000 bones.
