Fun with a Vacuum - Episode 15

If you have an empty jar, is it really empty? Take all the air out of it and you have a vacuum. When the pressure drops due to a vacuum, everything begins to behave in strange ways. Watch and see!

Inertia, Newton's First Law - Episode 14

If you want to move it, you have to push it! Things don't change their movement on their own, and scientists often call this the Law of Inertia. Watch as Dr. Carlson shows off an amazing series of demonstrations where things don't move!

The Return of Density - Episode 13

Some things float in water and others sink, but can the same thing both float and sink? Better yet, Dr. Carlson demonstrates water that sinks in water.

Density - Episode 12

Long-time viewers realize that Dr. Carlson is dense. In this episode, dignity is again laid on the line as we find out exactly how dense is... Dr. Carlson.

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!

Packing Peanuts - Episode 8

The mystery of styrofoam packing peanuts is revealed in this shocking episode demonstrating.... hmm, well it demonstrates cool stuff. After all, if you can't dissolve packing peanuts when you feel like it, what's the point of science anyway?

Free Fall - Episode 7

What does it feel like to float in outer space? How do satellites orbit the Earth? These mysteries, and more, are explained in this short video about gravity, orbits, and free fall.

Freezing by Boiling - Episode 6

It seems unnatural, but the laws of physics don't lie. Liquids require heat to boil, and if the conditions are right one liquid can be boiled in order to freeze a second. Under a vacuum, the water in an acetone/water mixure can freeze while the acetone boils.

Protein Folding - Episode 3

Eggs turn white when fried because their protiens are unfolded by the heat. Much of your body is made of large molecules called proteins that can perform chemical reactions. Proteins are like long strands of pearls that can fold up into balls in order to their job. Changes in the environment (like heat) can change whether proteins fold.

Science Theater Episode 3: Protein Folding

*As an aside, my PhD thesis research focused on this very topic.

Photons of Light - Episode 2

LEDs and photosensitive paper show light be a particle in this demonstration explaining how light comes in little "packets" that we call photons. Colored LEDs make phosphorescent paper glow only if their color (frequency) of light is high enough in energy.
