Welcome to 2006 AAPT visitors

I recently travelled to Syracuse, NY to present a short paper on podcasting science content at the AAPT (American Association of Physics Teachers).

For those who attended my talk (and any other curious folks), you may download the powerpoint file, which contains all the links necessary to set up your own (free) podcast...

Thanks for visiting, feel free to browse past videos or subscribe (to the RSS feed through iTunes or some other reader) to be alterted to future ones!

Concentration and Reaction Rates - Episode 10

Making Elephant Toothpaste is as simple as mixing two chemicals - causing an explosion of foamy science goodness. We take a look at two reactions with hydrogen peroxide to see how the concentration of H2O2 affects the rate of the reaction.

Newton's Third Law - Episode 9

How can a rocket engine lift itself off the ground? Push a wall and you will be pushed back. Newton's Third Law of Motion states that every force has an equal force applied in the opposite direction. If air, trapped in a fire extinguisher, is "thrown" backwards by releasing it, Dr. Carlson can be pushed forward by the blast - his very own jet-car!
