The National Gardening Association Biology teacher support IA material This teacher support material is designed to support new and experienced teachers in the application of the internal assessment criteria for the group 4 courses. The criteria can be found in the Diploma Programme Biology guide, Chemistry guide and Physics guide (published March 2007). The first part has three sections of general guidance for teachers. The second part shows the application of the criteria in the assessment of practical work.

Green Capitalism: The God That Failed (Image: Jared Rodriguez / Truthout) The results are in: No amount of "green capitalism" will be able to ensure the profound changes we must urgently make to prevent the collapse of civilization from the catastrophic impacts of global warming. The following is an updated version of an article that originally was published in the Real-World Economics Review. We consider Richard Smith's article foundational to understanding the world we live in. As soaring greenhouse gas (GHG) emissions drove global CO2 concentrations past 400 parts per million in May 2013, shell-shocked climate scientists warned that unless we urgently adopt "radical" measures to suppress GHG emissions (50 percent cuts in emissions by 2020, 90 percent by 2050) we're headed for an average temperature rise of 3 degrees or 4 degrees Celsius before the end of the century. All such market-based efforts are doomed to fail, and a sustainable economy is inconceivable without sweeping systemic economic change.

Milkwood: homesteading skills for city & country Great Lakes Fishery Commission - Asian Carp Asian Carp Four species of Asian carps, bighead carp, silver carp, black carp, and grass carp, are threats to Great Lakes fisheries. Recent peer-reviewed risk assessments for bighead carp and silver carp, and grass carp indicate that the Great Lakes are at substantial risk from these three species. All four Asian carps grow to large sizes approaching or exceeding 100 lbs and four feet in length. All four Asian carps were imported to North America to assist with pest control in aquaculture facilities, and have since escaped into the wild. Because of the threat these invasive carps hold for the Great Lakes, the commission is actively working with partner agencies to prevent their introduction and establishment. For more information about Asian carps, visit asiancarp.us.

Experience Just How Big the Universe is, in One Mind-Blowing Interactive You need a more recent version of Adobe Flash Player. Recently, NASA scientists combined data from the Spitzer and Hubble Space Telescopes to discover the most distant galaxy known to date. The galaxy, named Abell2744 Y1, was formed around 13.2 billion years ago when the universe was extremely young. As the universe is expanding, Abell2744 Y1 is currently closer to 40 billion light years away from us, an astounding distance.

Most of us have trouble visualizing the height of buildings, or the distance it takes to get home from work, let alone things on an intergalactic scale. Even cooler are the tidbits of information that are provided when you click on an object. 1. This is the smallest unit of scale in the universe. As you can see from the animation it takes a bit of zooming to reach this scale. 2. 3. 4. Tres-4 is the second largest planet discovered so far. 5. 6. 7.
