What do merry-go-rounds have to do with artificial gravity? Lean about the science of spinning when Dr. Carlson talks about circular motion and the centripetal force.

Science Theater Episode 16: Circular Motion

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!

Science Theater Episode 15: Fun with a Vacuum

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!

Science Theater Episode 14: Inertia - Newton's 1st Law

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.

Science Theater Episode 13: Density Changes

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.

Science Theater Episode 12: Density

Is nothing as thrilling as watching ice melt? Why do metals feel cold, while wood feels warm to the touch? All this and more in...

Science Theater Episode 11: Thermodynamics and Temperature

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...

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.

Science Theater Episode 10: Chemical Reaction Rates

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!

Science Theater Episode 9: Equal and Opposite Force

Who doesn't like a student pep rally? See the amazing blue colors turn orange! Marvel at the amazing orange colors turning blue! In this film, recently recovered from the archive, we see how science can have just as much orange and blue school spirit as the next subject!
