Dr. Carlson's Science Theater

Entropy. It's why everything seems to break down and get messy. It is something that comes about when you have lots and lots of little things (like atoms) that can be in several possible "states" (no, not Florida). The more things or more states you have, the more entropy you're going to have. Dr. Carlson has entirely too much fun playing with coins and blocks while he tries to explain how Chemists think of Entropy. (Stay to the end and you'll even see a rubber band, whee!)Science Theater Episode 39: Entropy

Winter is in the air, and it's cold out on the lake making it pretty easy to walk on water. Dr. Carlson visits his parents and takes time out to explain some cool science concepts that can occur when your lake freezes over. That's right, Dr. Carlson freezes his tooshie, just so you can expand your mind!Science Theater Episode 38: Walking on Water

Physics tells us that you can't know exactly where you are and where you are going at the same time! Heisenberg Uncertainty Principle explains that you can't measure a particle's exact velocity and location, Dr. Carlson takes on the challenge of explaining it all in this special, third anniversary, episode of...Science Theater Episode 37:Heisenberg Uncertainty Principle

Pity the poor high energy particle physicists. In order to perform an experiment, they have to destroy whatever they're looking at. Dr. Carlson explains how experiments on tiny particles are tricky. It's not easy to run experiments on things that are smaller than your tools.Science Theater Episode 36:A Particle Experiment

Can you change reality just by looking at it? Dr. Carlson says no! Watch on to see just what we mean when scientists talk about observers determining reality in this down-to-earth explanation of Quantum Mechanics.Science Theater Episode 35: Quantum Mechanics

Is the best path between two points a straight line? The second video in our brainteaser series challenges the viewer (you) to predict and explain any differences in the path of two rolling balls. Can you figure it out before the episode is over?Science Theater Brainteaser 02: A Straight Line

Do you have what it takes to explain science? Try to explain how this object actually rolls uphill in this episode. This video is the first of several Brainteaser episodes where you, the viewer, are presented with a problem and are challenged to explain the science behind the solution by the end of the episode.Science Theater Brainteaser 01: Rolling Uphill

Yes, he's done freezing by boiling before, but this time Dr. Carlson uses liquid nitrogen, a special tube, and a little water to demonstrate the power of sweat!Science Theater Episode 34: The Sweat Episode

How to make a cloud in a bottle in four easy steps. Dr. Carlson takes on a giant glass ball of green liquid in an attempt to eplain how clouds are formed. In a never-before seen feature, this episode even includes Director's Commentary for the first segment. Yes, it's a feature, not a bug.Science Theater Episode 33: Making CloudsFeel free to drop by our home page at www.ScienceTheater.net!Note, technically this episode is 33b, as it takes the place of The Sweet Spot - Episode 33, removed due to a few mistakes in the science of hitting balls with bats.

Fluorescence, it's almost as hard to explain as it is to spell. Dr. Carlson explains how his favorite color (neon) is such a shiny glowy thing and how detergents can get your clothes "whiter than white!"

Liquid air? Once Nitrogen gas becomes really, really cold it becomes a liquid. Once you have really, a really cold liquid, you can use it to make other things cold. Really, really cold things behave differently. Join Dr. Carlson to find out how cold things behave in...Science Theater Episode 31: Liquid AirFeel free to drop by our home page at www.ScienceTheater.net!

Sure, gas-liquid-solid... you've seen it all before, but have you seen air as a gas, air as a liquid, and air as a solid? Dr. Carlson explains the three most common states of matter and shows off how to make a snowcone out of Nitrogen gas.Science Theater Episode 30: States of MatterFeel free to drop by our home page at www.ScienceTheater.net!

We're back at PRIME lab to take a look at the giant particle accelerator. Learn the process of taking a glacier rock, pounding it to smithereens, and then shooting it down a beam at hundreds of miles an hour, just to count how many atoms of Beryllium are inside the rock! A little bit of science for everyone: Chemistry, Physics, and Geology!Science Theater Interview 06: Marc Caffee (Part 2)Science Theater Interviews: Real Scientists, Real Science

There's nothing like taking tiny little bits of rock and smashing them with Cesium to send them on an electrical journey at ultra high speeds. That's just what happens in the particle accelerator at Purdue's PRIME Lab. In our most recent Interview with a Scientist episode, Prof. Marc Caffee explains how he can find the age of asteroid rocks from outer space or determine how long ago rocks were exposed from glacier movement.Science Theater Interview 05: Marc Caffee (Part 1)Science Theater Interviews: Real Scientists, Real Science

When does a tower tip and fall? When its center of mass is no longer over its base. Dr. Carlson plays with blocks and walks the plank in order to illustrate the power of center of mass.Science Theater Episode 29: Center of MassIf you haven't seen it yet, be sure to visit my new home page at: www.ScienceTheater.net!

Lasers and bacterial cells - they go together like peanut butter and jelly. Prof. Ken Ritchie, Professor of Physics at Purdue uses lasers to "light up" individual molecules on the surface of cells. By taking pictures and videos of these cells he can study cellular processes that help single cell organisms build their membranes and orient themselves in their environment.Science Theater Interview 04: Ken Ritchie

Mirrors don't let you see things that aren't there, they let you see things from an entirely different position! Your image in a mirror is what someone else would see if they were standing behind the mirror. It's all a matter of tracing the path of light from your eye to an object, or from the object to your eye.Science Theater Episode 28:Mirrors and ImagesIf you haven't seen it yet, be sure to visit my new home page at: www.ScienceTheater.net!

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

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! Science Theater Special Edition: Orange Crush Spirit Chemistry

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?Science Theater Episode 8: Packing Peanuts

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.Science Theater Episode 7: Free Fall

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.Science Theater Episode 6: Freezing by Boiling

Hot stuff and cold science explain temperature and its affect on chemical reactions. Crowd-pleasing lightsticks make their return in this episode focusing on temperature.Science Theater Episode 5: Temperature

Can-crushing, balloon-inflating, juice-box-drinking action in this study of air pressure: how it happens, what it is, and why.Science Theater Episode 4: Air Pressure

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.

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.Science Theater Episode 002: Photons of Light

Liquid light can be mixed to create pure white light. In the premiere episode, "lightstick juice" is used to demonstrate how red, green, and blue light can be mixed to create white light. All it takes is a few colored light sticks, a knife, and a paper towel...Episode 1
