"Students can learn some science concepts just as well from computers simulations as they do from direct observation, new research suggests. See Also: Mind & Brain Educational Psychology Language Acquisition Space & Time Moon Pluto Computers & Math Computer Modeling Computer Science Reference Computer simulation Instructional design Computing power everywhere Local area network A study found that people who used computer simulations to learn about moon phases understood the concepts just as well -- and in some cases better -- than did those who learned from collecting data from viewing the moon."

"Model and Solve Math Word Problems Thinking Blocks is a suite of learning tools designed to help students solve math word problems accurately and efficiently. Using brightly colored blocks, students model mathematical relationships and identify known and unknown quantities. The model provides students with a powerful image that organizes information and simplifies the problem solving process. By modeling increasingly complex word problems, students develop strong reasoning skills which will facilitate the transition from arithmetic to algebra."

Researchers have found a way to make multiple high-performance anodes from a single silicon wafer. The process uses simple silicon to replace graphite as an element in rechargeable lithium-ion batteries, laying the groundwork for longer-lasting, more powerful batteries for such applications as commercial electronics and electric vehicles.

""Save the World Through Science & Engineering" 2012 Kavli Foundation Science Video Contest Make a video that dazzles and wows us with the POWER of science! Show us how science and engineering can help save our planet and improve our lives. Winners will be honored in a special festival Awards Show and receive cash prizes! Contest opens Oct 1,2011 and closes Mar. 21, 2012"

"re-purposing two NRO telescopes appears to be a wonderful Band-Aid for a tricky space telescope problem. Also, as hardware construction consumes a lot of funds and time ahead of any space telescope mission, these two telescopes would save NASA a lot of cash."

"The researchers demonstrated that an "electrified" snail could be a living battery producing up to 7 milliwatts. Although the power output decreased rapidly, feeding the snail could partially refuel it straight away. Alternatively, allowing the snail to rest for about half an hour would allow it to recharge. "

"the ability to search for books by author, title, award/list year, genre, by award, and by booklist a Find It! button, powered by the OCLC WorldCat Search API, that will show users where to find the book in a nearby library a Favorites button, to create an individualized booklist"

"iCivics is a great way for students to learn about civics in the United States. The site features 16 educational video games that help students understand our government. In addition to the great games, iCivics has great standards-aligned civics curriculum available for free to teachers! Games include topics like: Citizenship and Participation, the Constitution and Bill of Rights, Budgeting, Foreign Policy and National Defense, Separation of Powers, the Executive Branch, the Legislative Branch, and the Judicial Branch.

"Rover is the only education browser for your iPad, designed specially for teachers and students of all ages. Rover brings the best K-12 online learning content to your fingertips, including access to content ordinarily unavailable on the iPad (e.g. Flash content). Rover is powered by the iSwifter platform (the world's first cloud-based Flash streaming platform for mobile devices), and is specifically designed based on guidance from teachers, IT directors and administrators from schools around the country.

"The Postal Service solved the problem with the world's first ground-based civilian navigation system: a series of lit beacons that would extend from New York to San Francisco. Every ten miles, pilots would pass a bright yellow concrete arrow. Each arrow would be surmounted by a 51-foot steel tower and lit by a million-candlepower rotating beacon. (A generator shed at the tail of each arrow powered the beacon.) Now mail could get from the Atlantic to the Pacific not in a matter of weeks, but in just 30 hours or so."

"Students construct balloon-powered racing cars using a foam tray and drinking straws. They then test the cars along a measured track on the floor. At the conclusion of the activity, students submit a detailed report on their racer design and how it performed in the trials."

Torque Meter - Journal of the Aircraft Engine Historical Society articles on all types of aircraft engines, both new and old. Topics included engines and the aircraft they powered with emphasis on the engine installation, propellers, accessories, cooling, operation, and maintenance. Torque Meter is no longer published. However, All Torque Meter Back Issues Are Still Available!

The Collings Foundation has recovered and restored many of the true landmark aircraft that built world aviation history. Aircraft from the very roots of aviation up until the supersonic jets of modern day are represented in the collection which spans nearly 80 years of powered flight. Many of the aircraft are viewable to the public at airshows, events, and airports around the United States.

To Dietrich, whose Transition is designed to be able to drive home from the airport, Fuller said, "What were you thinking?" The MIT graduate laughed and said that she and her team believe in the reality of a roadable aircraft. "It will be a tool, but it will also be an adventure vehicle. The power of light sport combined with automotive technology ... ."

home laboratories have tools like infrared thermometers Many of these tools work closely with home computers and come with software that enhances their power. Others mix low-cost computers into the hardware to deliver more precise control. Some people who set up home laboratories are serious hobbyists in search of better tools; others are home-schooling parents equipping their children; and others are just curious.

Reichert became the first person to fulfil the vision Leonardo DaVinci set down in his notebooks in 1485 - of flying a human-powered vehicle through the air like a bird. "This is the original aeronautical dream," Reichert says. "Humans have always wanted to fly like birds.

December 30 - In 1905… The Wright brothers sign a contract for one million francs with Frenchman Arnold Fordyce for the sale of a powered flying machine capable of flying a nonstop distance of 31 mi. When contingent of French government officials come to Dayton in April 1906 to change the agreement by seeking exclusivity for one year, the idea is dropped; for their trouble, the Wrights received 25,000 francs (then about US $5,000), the first money they earn from flying.

Hugues Duval in a Cri Cri aircraft powered by two 35 hp Electravia electric motors - Aerospace giant EADS building the little 4-motor electric Cri Cri and then right on their heels was this one pictured here that uses two 35 hp electric motors from Electravia. Both actually had their first flights back in September.

LESSON PLANS - A library of fun science experiments to help students understand how the Wrights developed the first powered aircraft. WIND TUNNEL TESTS In 1901, the Wright Brothers conducted wind tunnel tests that helped them learn about lift. With NASA's help, we'll recreate some of those tests. Follow along! COMPUTER SIMULATIONS We're using computers to analyze the Wrights' early wing designs and the 1903 Wright Flyer. What will we learn?

Steam aircraft are aircraft that are propelled by steam engines. They were unusual devices because of the difficulty in producing a powerplant with a high enough power to weight ratio to be practical.
