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.

Population pyramids: Powerful predictors of the future - Kim Preshoff If your selected country was not represented by a population pyramid in the lesson, you may wonder what it looks like. The U.S. Census Bureau has an International Data Base that can help you create one. Is your country a fast, slow or no growth pyramid?The current world population can be seen ticking on the World Population Clock. Factors such as better water, food, medicine, industry, and health care have caused the world population to grow exponentially. 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

7 talks on how we make choices | Playlist Now playing Over the years, research has shown a counterintuitive fact about human nature: That sometimes, having too much choice makes us less happy. This may even be true when it comes to medical treatment. Baba Shiv shares a fascinating study that measures why choice opens the door to doubt, and suggests that ceding control — especially on life-or-death decisions — may be the best thing for us.

'Cool Blue' Energy Efficiency Public release date: 1-Jun-2012 [ Print | E-mail Share ] [ Close Window ] Contact: Mas 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.

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

Graduation…now what? | Playlist Now playing Clinical psychologist Meg Jay has a bold message for twentysomethings: Contrary to popular belief, your 20s are not a throwaway decade. In this provocative talk, Jay says that just because marriage, work and kids are happening later in life, doesn’t mean you can’t start planning now. She gives 3 pieces of advice for how twentysomethings can re-claim adulthood in the defining decade of their lives. “In your 20s, you may not get married or figure out exactly what career you want to pursue.
