"In this activity you should use your knowledge of forces to explain how animals move! Remember that it is normally the reaction force on the body of an animal which gives rise to the resultant force. To obtain a reaction force, an action force must be applied in the opposite direction. There must be a resultant force on the body to change the velocity of the body. "

"We'll travel to NASA's tool lab and see the equipment we need to build in this challenging environment, from high tech wrenches and hammers"

"Recognizing that the cost of learning to fly can pose a significant barrier for some student pilots, AOPA earlier this year established two $5,000 flight training scholarships-the AOPA Flight Training Scholarship and the Erral Lea Plymate Memorial Scholarship. In addition, Aviation Supplies & Academics (ASA) and Jeppesen-two of the world's leading providers of flight training materials-approached AOPA to provide scholarship funds as well. To qualify, applicants had to hold a student pilot certificate but not yet a pilot certificate, complete an online application, and receive two recommendations."

"The National Aeronautic Association has certified the July 13 record for the University of Maryland's human-powered helicopter called Gamera. It achieved liftoff and hovered for 11.4 seconds, setting U.S. records for flight duration and for flight duration by a female pilot. (Watch a video of the flight.). It was designed and built by graduate and undergraduate students at the University of Maryland's A. James Clark School of Engineering and piloted by biology student Judy Wexler. "

"Taylor De Ley of Yorba Linda, Calif., may be only 17, but as he starts his college education this week he has already focused on a professional pilot career and completed a 10,492-nautical-mile solo flight to the four corners of the nation. That's more than most kids his age. He now has 340 total flying hours. He dedicated the flight to giving fellow teens who are "stuck playing video games" a taste of the flying adventure "

"surveillance drone. The nano air vehicles (NAVs), modeled after falling Maple leaf seeds, are designed to be super light weight and agile for vertical lift off, hovering, and navigation in tight spaces. "

""Flying his jet-propelled wing attached to his back, and steering only by movement of his body, Rossy launched from a helicopter at 8,000 feet into the breathtaking blue of the Grand Canyon sky," the release said. "Skimming the rockscape at speeds of up to 190 mph, Jetman sustained flight for more than eight minutes, 200 feet above the rim of Grand Canyon West."

"One of the biggest challenges in teaching science, technology, engineering, and math is capturing the students' imaginations long enough for them to see all of the possibilities that lie ahead," the company wrote on the Learn with Portals site. "Using interactive tools like the Portal series to draw them in makes physics, math, logic, spatial reasoning, probability, and problem-solving interesting, cool, and fun, which gets us one step closer to our goal-engaged, thoughtful kids!"

"Here are 18 practical strategies to turn your inclusion experiences into award winning classroom performances."

"The Navy has released video of the April 11 one-engine landing made by an F/A-18C aboard the USS Carl Vinson and during which the aircraft caught fire. ... Flight deck fire crews responded and the fire was extinguished with aqueous film forming foam. ... its pilot escaped the episode uninjured."

"A group of students at Chevak High School, located on the remote Alaskan tundra, worked together over the winter to build a Rans S-6s Coyote II experimental aircraft from a kit, and flew it for the first time on March 24. "The aircraft was beautifully built and was obviously the pride of the aeronautics class at the school," John Davis, a Designated Airworthiness Representative who flew in from Anchorage to inspect the airplane, told the Alaska Dispatch."

"WeatherSpark is a new type of weather website, with interactive weather graphs that allow you to pan and zoom through the entire history of any weather station on earth. "

"He believes that tens of thousands of visitors will flock to his Museum of Mathematics, to open in Manhattan next year, and leave invigorated about geometry, numbers and many more mathematical notions. "

"3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Advanced 3D printing technologies yield models that can serve as product prototypes."

"students take on the role of research team surrounding one of 12 different types of labs on any given unit."

"The relativistic motion of clocks on board GPS satellites exactly accounts for the superluminal effect in the OPERA experiment, says physicist Ronald van Elburg at the University of Groningen in the Netherlands, The Physics arXiv Blog reports."

"this organic star dust is similar in structure to complex organic compounds found in meteorites. Since meteorites are remnants of the early Solar System, the findings raise the possibility that stars enriched the early Solar System with organic compounds. The early Earth was subjected to severe bombardments by comets and asteroids, which potentially could have carried organic star dust. Whether these delivered organic compounds played any role in the development of life on Earth remains an open question."

"Is it a bird? Is it a helicopter? No, it's the world's first ever manned multicopter. A German engineering company has just managed to put a man flight using the technology normally used for flying model toys."
