"In a longitudinal wave the particles vibrate parallel to the direction the wave is travelling in...not at 90 degrees as for waves on a string. A longitudinal wave can be shown using a slinky spring; have a look at the animation below:"

"Rachel Simmons is passionate about teaching her students to be responsible leaders and citizens as well as accomplished artists. Her interests range from collaborative community art projects to climate change, marine pollution and ecotourism. Research and geography inform her work; she traveled to Antarctica in 2008 and 2009, and will visit Iceland this summer to study appropriate scale and the sustainable landscape. "

"As we approach the Mars rover Curiosity's landing Sunday night, we're having a lot of fun seeing all the promotions - there are all kinds of videos, museum exhibits and road shows to help explain what the newest interplanetary explorer will do. Below is a great new one from the American Chemical Society. Curiosity is a well-equipped geologist, traveling to Mars with a suite of tools to bake and pulverize rock, but it's also a trained chemist, capable of detecting the ingredients necessary for life as we know it. It's the first explorer to be able to do this. "

"To celebrate Moon Day, catch up on the latest in lunar exploration and space travel. The ideas worth sharing here are the first steps in the next giant leap for mankind."

"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."

"Seven of the eight students traveled to AirVenture to spend a week at the show promoting the GAMA/Build a Plane project. Adhering to a schedule as packed as that of any airshow performer, they stopped at the GAMA/Build a Plane exhibit on July 29 to visit briefly with "their" airplanes. "

"science, technology, engineering, and math (STEM) software that bridges the gap between the excitement of gaming and the fundamentals of curriculum-based learning. We are an extremely passionate educational software company committed to one mission: creating relevant, exciting and useful educational software with the same level of quality found in entertainment titles. Our newest product, Time Engineers, teaches engineering, science, and math without leaving the fun of gaming behind. Students travel in a cool time machine to three different time periods and encounter typical engineering problems to be solved in order to build pyramids, irrigate farm land, command a WWII submarine, raise and lower medieval drawbridges, and much more."

NASA education - understanding of the universe, advanced technology breakthroughs, enhanced air travel safety and security, and expanded the frontiers of scientific research. promoting excellence in science, technology, engineering and mathematics education to ensure that the next generation of Americans can accept the full measure of their roles and responsibilities in shaping the future.

In this activity students will be able to view the different ways water travels and the different forms in which water can be found. The experiment focuses mainly on evaporation, transpiration, condensation and precipitation

To measure this acceleration we will drop a magnet and measure the time taken for the magnet to travel between two points. This information used with the distance formula below will allow us to calculate the acceleration of the magnet due to gravity.

"Today In Aviation History - December 31 - In 1908… Wilbur Wright at Auvours, France, makes the first flight over 2 hours. He flies for 2 hours and 20 minutes, covers 77 miles, and wins the Michelin Cup for 1908. In 1951… This year, for the first time, air passenger miles flown (10.6 million) have exceeded passenger miles traveled in Pullman cars on the railroad (10.2 million). In 1958… This year, for the first time, more passengers (1.2 million) have crossed the North Atlantic by air than by sea."

The show has been presented by Professor Clint Sprott on the Madison campus over 200 times to a total audience of about 70,000. In addition a traveling show has been developed and presented by physics graduate students and staff over a thousand times to audiences of all ages throughout Wisconsin and the nation. A variety of educational tools and materials have been developed including videos, software, a demo book, and a lecture kit.

The space shuttle has made space exploration history over the past 30 years by regularly traveling through extreme temperature fluctuations. Scientists and engineers collaborated to develop unique materials to withstand extreme temperatures. This led to the development of the unique "skin" of shuttle tiles. NASA is offering space shuttle tiles to schools on a first-come, first-served, one-per-institution basis. The Structure and Materials Shuttle Tile Educator Guides contain mathematics- and science-related activities for using the tiles.

What do fireworks, love and butterflies have in common? How do muscles work? How do colours appear? What kinds of levitation are possible? Why can we see the stars? Is time travel possible? What is the maximum force found in nature? Which problems in physics are still open? This free physics textbook provides the answers - and guarantees as much pleasure as whatever else you enjoy most in life.

"Being greener at school There are many environmentally-friendly things you can do at school or college to help protect the planet and prevent climate change. These include setting up recycling schemes and finding greener ways to travel to and from school."

"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"

"Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium. There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves. The animations below demonstrate both types of wave and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is travelling."

Those memories begin in 1966, and long lines of interesting aircraft spring to mind. "Monthan" is Davis-Monthan Air Force base at Tucson, Arizona. Home of AMARC * or MASDC * as it was known when I first "scouted" it out, travelling there all the way from Scotland. As a schoolboy, I had seen a few photographs of a "Boneyard" in Arizona. They showed stacks of Republic F-84F and F-84G Thunderjets piled four high, that captivated me, it still does. I have made several trips to Tucson and hope to visit a few more times. In this section I will be adding photos and slides taken during these visits, mostly in 1968, when I spent two days walking the base with my good friend Tom Baillie.
