20 Gifs That Teach You Science Concepts Better Than Your Teacher Probably Can These Gifs are astoundingly elegant. 10) Here’s how you convert Cartesian (rectangular) to Polar Coordinates 9) This is how Exterior Angles of Polygons work (they add up to 360 degrees) 8) This is a Hyperboloid made up of straight lines 7) This is also a Hyperboloid of straight lines 6) This is how White Blood Cells keep you safe (in the video, a white blood cell chases and engulfs this bacteria–watch until the end!) 5) This is Earth’s ice and vegetation cycle over a year 4) There is Flammable Matter in Smoke (it’s not just nothingness, obviously) 3) This is what it looks like when you set a Flammable Gas on fire in a glass jar 2) This is vortex pinning (A superconductor levitates over a magnetic track) 1) This is how Tension works in relation to falling objects (watch a slinky fall to the Earth; this is how slinkies always fall) Over the course of a single year, we compile thousands of articles, and generate dozens upon dozens of high-quality videos and infographics. Stop by and say hello.
German Aerospace Center To Develop High Performance Fuel Cell Powered Aircraft - Ecofriend German Aerospace Center to develop high performance fuel cell powered aircraft Eco Factor: Zero-emission aircraft to be powered by hydrogen fuel cells. The German Aerospace Center is working with Lange Aviation GmbH to develop next-generation fuel cell powered aircraft, the Antares H3. The Antares H3 is the successor of the Antares DLR-H2 aircraft, which was the first piloted aircraft capable of flying solely on hydrogen fuel cells. The Antares H3 will be developed to set new range and endurance benchmarks with first flight scheduled to take place in 2011. Based on the Antares 20E as well as the Antares DLR-H2, the Antares H3 will use fuel cells instead of batteries, where hydrogen will combine with oxygen taken from surrounding air to produce electricity with water as the only byproduct. The developers plan to achieve a range of up to 6000km and endurance of more than 50 hours with the Antares H3. Via: The Engineer Enjoyed this post? Categories: Uncategorized Tags:

Ten Websites for Science Teachers We all know that the web is full of excellent web resources for science teachers and students. However, unless you live on the web, finding the best websites can become quite a challenge. This isn't a "Top Ten" list -- instead, it is a list of websites that I either use on a regular basis or just find interesting. From teaching resources for the nature of science and authentic field journals to wacky videos about numbers, I am sure that you will find something in the following list the works for you! 1) Understanding Science UC Berkeley's Understanding Science website is a "must use" for all science teachers. 2) Field Research Journals The Field Book Project from the National Museum of Natural History and the Smithsonian Institution Archives intends to create a "one stop" archive for field research journals and other documentation. 3) Evolution Berkeley's Understanding Evolution website is the precursor to their Understanding Science efforts. 4) PhET Simulations 5) Earth Exploration video
'Cool Blue' Energy Efficiency Public release date: 1-Jun-2012 [ Print | E-mail Share ] [ Close Window ] Contact: Mas Subramanianmas.subramanian@oregonstate.edu 541-737-8235Oregon State University CORVALLIS, Ore. – A new type of durable, environmentally-benign blue pigment discovered at Oregon State University has also been found to have unusual characteristics in reflecting heat – it's a "cool blue" compound that could become important in new approaches to saving energy in buildings. The compound, which has now received patent approval, was discovered about three years ago almost by chance, as OSU scientists were studying some materials for their electrical properties. Its potential use to help reduce heat absorption on the roofs and walls of buildings – which is an evolving field of considerable interest in warm regions where cooling is a major expense – adds another role for the material, which is now being considered for various commercial applications.

Psykologiprofessor gör upp med självhjälpstrenden Det finns många som profiterar på den vilsenhet människor känner i dagens samhälle, framhåller Svend Brinkmann. – Coachernas råd är ofta att ”gå på magkänslan” och att ”lita till din inre röst”. Men jag tror att det kan förstärka vilsenheten och göra att människor mår ännu sämre. Svend Brinkmann arbetar vid universitetet i danska Ålborg. Varje år säljs tiotusentals självhjälpsböcker i boklådor och på nätet i såväl Danmark som Sverige. ”Självutvecklingsfilosofier” frodas på jobbet och i olika utbildningar. I det moderna samhället präglas livet av ständig omställning och förändring, en utveckling som ofta gör många människor vilsna och förvirrade. – I dag blir människor utbrända, deprimerade och upplever en tomhet i sina liv. Allt är nämligen inte individrelaterat, menar Svend Brinkmann. – Alla krav på förändring och flexibilitet gör att människor upplever en meningslöshet – och tror att de inte tillräckligt noga lyssnat till just sin ”inre röst”.

What is science about? / Science / Learning areas / The New Zealand Curriculum Mā te whakaaro nui e hanga te whare;mā te mātauranga e whakaū. Science is a way of investigating, understanding, and explaining our natural, physical world and the wider universe. It involves generating and testing ideas, gathering evidence – including by making observations, carrying out investigations and modelling, and communicating and debating with others – in order to develop scientific knowledge, understanding, and explanations. Scientific progress comes from logical, systematic work and from creative insight, built on a foundation of respect for evidence. Different cultures and periods of history have contributed to the development of science. Return to top
Environment: Climate Change, Natural Resource Management And Integration Climate change and environmental degradation pose threats to the global economy and to the well-being of citizens in every country. These interacting processes have the potential to undermine development investments and recent gains in poverty alleviation, food and water, security and human health, particularly in the most vulnerable developing countries. Though the poorest countries historically have been least responsible for climate change and ecosystem degradation, they face the most severe consequences of its effects (ranging from altered rainfall, reduced crop yields and increased weather-related disasters, to rising sea levels and exacerbated disease). Reducing vulnerability and building resilience to ecological changes are best viewed as development challenges. Decisions on policies and programs for resource management need to be based on broad citizen participation and the engagement of rural communities that have often been disenfranchised or marginalized.
