Most of us take gravity as an assumed part of our living realities, but why? Basic physics introduces us to the concept of gravity from a Newtonian sense, but when you start factoring Einstein into an understanding of gravity, things get...

In this video Paul Andersen explains how heating is the transfer of energy (heat) from a warmer object to a cooler object. Heat can be transferred through conduction, convection and radiation. At the microscopic level conduction...

In this video Paul Andersen explains how the pressure, volume, amount, and temperature of an ideal gas are related. Absolute zero of a gas can be determined by varying the temperature and measuring the corresponding volume of a gas...

Sam the Bat is visiting today, and Jessi wants to use a cool trick to show him how we use a special part of our body to sing.

Squeaks is feeling a little under the weather! As if a sore throat and a stuffy head weren't bad enough, he also has an earache. Join him to learn why we get earaches and what we can do to help our bodies get over them faster!

In this video Paul Andersen explains how all objects contain positive and negative charge. Neutral objects contain an equal amount of positive and negative charges. Charged objects have more positive or negative charges. Like charges...

The science of hot air balloons may surprise you.

Hank bursts our ideal gas law bubble, er, balloon, and brings us back to reality, explaining how the constants in the gas law aren't all that constant; how the ideal gas law we've spent the past two weeks with has to be corrected...

The name “The Big Bang” makes it sound like there was a big explosion in one particular spot, but if that’s the case, where did it happen?

Hot Air Balloons! They're those big, beautiful balloons people can float up to the sky in-- but how do they get up there?!

In this video Paul Andersen explains how gases differ from the other phases of matter. An ideal gas is a model that allows scientists to predict the movement of gas under varying pressure, temperature and volume. A description of both...

Gases are everywhere, and this is good news and bad news for chemists. The good news: when they are behaving themselves, it's extremely easy to describe their behavior theoretically, experimentally and mathematically. The bad news is...

Is the universe expanding? About a hundred years ago astronomers made a discovery that helped us unravel the mystery of the history of the universe!

Sometimes science can look a lot like magic! This week, Jessi will show you how to make a balloon stick to the wall; no tape required! Stick around to learn how she did it and the science that makes the trick work! Abracadabra!

Hank reaches the fourth and final of the four fundamental interactions in physics: electromagnetism. In this part, he teaches us about the electrostatic force, which builds up a charge in an object and can travel in the form of an...

How can bottles and balloons help explain the different laws that govern gas? See how Boyle's Law, Charles' Law, and Avogadro's Law help us understand the laws that govern gas properties.

Can you believe that you can blow up a balloon without actually blowing your own air into it!? Follow along with this super neat experiment and find out how!

Mr. Andersen surveys properties of matter. A brief discussion of Archimede's Principle, Charles Law, Boyle's Law, and viscosity is included.

Hey... what's matter? No no no, not what's THE matter. What's MATTER? In this episode of Crash Course Kids, Sabrina talks about what matter is and the three states of matter: Solid, Liquid, and Gas. She also does a quick experiment that...

Weight Distribution! WOW!

What other senses can these students use to understand the experiment?

Does the world’s most common pain relief drug do more than just reduce pain? Recent headlines would have you believe that it also reduces your perception of risk, resulting in more risk-taking behaviors. We think it’s time to take a...

Let Me Do It Poem from A Great Big Cuddle

Where is the center of the universe? All this, everything you see around you, started in a big bang, from a point smaller than the point at the end of this sentence. It as an infinitesimally small point, called a singularity....
