Fakta om luft och värme | UPPTÄCKARGLÄDJE -Luft och lufttryck Luft är en blandning av olika gaser och består mest av kväve och syre. När ett ämne är i gasform sitter inte molekylerna ihop utan far omkring. Molekylerna i luften rör sig en och de är alldeles för små för att vi ska kunna se dem. -Luftmotstånd Luftmotstånd är en kraft som är riktad mot färdriktningen och saktar in allting som färdas genom luften. -Luftens krafter Luften och dess krafter kan föra fram segelbåtar, driva vindsnurror och väderkvarnar. -Värme I värme rör sig molekylerna snabbare, ämnen utvidgas och tar större plats.

12 NASA Apps for Students to Learn about Space April 16, 2014 Last night while I was watching the total lunar eclipse " Blood Moon", it dawned on me to compile a list of iPad apps that students can use to learn more about space. Of course there are no better apps to recommend than NASA's. I have gone through all the apps NASA offers and picked out for you the ones below. Have a look and share with your colleages. 1- Spacecraft 3D NASA's Spacecraft 3D is an augmented reality (AR) application that lets you learn about and interact with a variety of spacecraft that are used to explore our solar system, study Earth, and observe the universe. 2- Moon Tours Moon Tours is the mobile version of the NASA's Lunar Mapping and Modeling Portal (LMMP). 3- 3D Sun "3D Sun" lets you carry a virtual window onto today's sun, right in your pocket. 4- NASA Lunar Electric Rover Simulation Welcome to the NASA Lunar Electric Rover (LER) Simulator. 5- Images of Change 6- NASA App 7- Cassini 8- Space Junk Spammy 9- Space Place Prime 10- NASA Television
Experimentskafferiet Vatten och luft MadSciNet: The 24-hour exploding laboratory. Science, ICT, and the Global Classroom (Crowd-Sourced Notes) - ARKive - Extensive Animal Encyclopedia Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. With the help of over 7,000 of the world’s best wildlife filmmakers and photographers, conservationists and scientists, Arkive.org featured multi-media fact-files for more than 16,000 endangered species. Freely accessible to everyone, over half a million people every month, from over 200 countries, used Arkive to learn and discover the wonders of the natural world. Since 2013 Wildscreen was unable to raise sufficient funds from trusts, foundations, corporates and individual donors to support the year-round costs of keeping Arkive online. Therefore, the charity had been using its reserves to keep the project online and was unable to fund any dedicated staff to maintain Arkive, let alone future-proof it, for over half a decade. Therefore, a very hard decision was made to take the www.arkive.org website offline in February 2019.

The Ten Most Disturbing Scientific Discoveries Science can be glorious; it can bring clarity to a chaotic world. But big scientific discoveries are by nature counterintuitive and sometimes shocking. Here are ten of the biggest threats to our peace of mind. 1. The Earth is not the center of the universe. We’ve had more than 400 years to get used to the idea, but it’s still a little unsettling. … his contemporaries found his massive logical leap “patently absurd,” says Owen Gingerich of the Harvard-Smithsonian Center for Astrophysics. Galileo got more grief for the idea than Copernicus did. 2. Antibiotics and vaccines have saved millions of lives; without these wonders of modern medicine, many of us would have died in childhood of polio, mumps or smallpox. The influenza virus mutates so quickly that last year’s vaccination is usually ineffective against this year’s bug. 3. The concept of extinction took a while to sink in. Today, according to many biologists, we’re in the midst of a sixth great extinction.
