"In a paper published Thursday in Science, demographers from several universities and the United Nations Population Division conclude that instead of leveling off in the second half of the 21st century, as the UN predicted less than a decade ago, the world's population will continue to grow beyond 2100."
A new simulation illustrates the explosiveness of the volcano that lurks beneath Yellowstone National Park in Wyoming.
Around 640,000 years ago, the volcano blew its top and coated North America with roughly 1,000 cubic kilometers of ash, enough to fill Lake Erie twice over. A simulation of the eruption described August 27, 2014 in Geochemistry, Geophysics, Geosystems reveals that a similar outburst today would bury Billings, Mont., in more than a meter (about 40 inches) of volcanic glass shards and pulverized rock. Even New York and Atlanta would receive dustings several millimeters thick as winds whisked ash through the darkened atmosphere for days.
Researchers used simulation software called Ash3d that forecasts ash fall by applying global wind patterns to data from historical eruptions. Ash3d churns out results several times faster than previous simulators and is the first program to incorporate the physics of how ash particles clump within a cloud.
While geologists say Yellowstone will likely never erupt again, scientists around the world use Ash3d daily to predict the potential fallout from restless volcanoes — including Bárðarbunga, the Icelandic volcano that began erupting in late August.

TEST Teaching Google Natives To Value Information by Terry Heick The usual term is a digital native–students born into our digital, connected, and uber-social world who have always had Wikipedia to ask questions, and Google to bail them out.
The ICCARS Collaboratory is an eLearning portal and community workspace for grade 8-12 teachers, students, and other collaborators participating in the Investigating Climate Change and Remote Sensing (ICCARS) project. ICCARS is a NASA funded two year program run by Wayne RESA and the Institute for Geospatial Research and Education (IGRE) at Eastern Michigan University.
TEST 48 iPad Apps That Support A Student-Centered Workflow by TeachThought Staff If you use iPads in your classroom, you’ve likely been faced with the challenge of workflow–how work, data, and thinking are distributed, collected, and aggregated.
To ensure productive group work, teachers must communicate expectations, strategically build groups, structure activities, scaffold work with a supportive classroom culture, and stress individual accountability.
Diane Johnson's insight:
The science and engineering practices often call for collaboration among students. Specific collaboration skills will need to be taught.
"This is what a pyrocumulus cloud caused by the burning of over 28,000+ acres of forest looked like as the sun set. In person as these clouds were changing it wasn't all that noticeable when the huge plumes of smoke changed shape, but thanks to the magic of a time-lapse we get to behold the violent nature of the smoke cloud, including a storm cloud that emerged behind the main pyrocumulus."
A 6 Step Process For Teaching Argument Analysis by Terry Heick How “basic” this is depends on who your audience is, but this is more of an overview to help students systematically look at an argument piece by piece–and these are the pieces.
Diane Johnson's insight:
Although this is from a ELA perspective, many of the questions will help with scientific arguments.
