"These are some educational java applets I wrote to help visualize various concepts in math, physics, and engineering. You should be able to view them with any Java-capable browser. "

"Science cartoon - physics basics: force, weight, energy"

"Being able to fly off on holiday is something we may take for granted. But how does the big metal tube you're flying in stay up in the air? We'll find out in the latest Naked Science Scrapbook. Plus we'll see that if the plane's engines stop working, you won't just plummet out of the sky"

"Humans have wanted to fly for thousands of years. Modern jet engines allow us to fly more efficiently, at greater speeds than ever before. In this Naked Science Scrapbook, we'll find out how engineers stop the engines from melting at such high temperatures, and why you couldn't run a plane on coal"

"apps where the students are still presenters but do so digitally. This means they can share the presentation, embed it in the digital portfolio and even let mum and dad see their work. Some of these even allow you to create an avatar or use a photo and then import it into the app to have your students present as themselves."

A wave is defined as the transfer of energy from one point to another. There are two large, all encompassing categories of waves: mechanical and non-mechanical.

All kinds of stringed instruments - guitars, pianos, violins - have stretched strings which oscillate when plucked or struck. This oscillation generates sound, which can be amplified acoustically by coupling the vibrations to a large sound-board (for a guitar, the top, and in an upright piano, at the back) or electrically by turning the string oscillations into an electrical signal (using a 'pickup') which can be sent to an electronic amplifier / loudspeaker.
