We know that gases move throughout and out of our bodies, but why? And how? Learn about gas movement by analyzing rates of effusion. Additionally, watch an interesting precipitate reaction using gases to apply effusion, diffusion, and...

The Hindenburg and its use of the highly flammable gas hydrogen, used to keep it afloat, eventually caught fire and killed 36 people.  Use the Ideal Gas Law through analysis of the Hindenburg and discover why scientists chose...

Amaze class members with the fact that solids, liquids, and gases all have the same particles. Kinetic theory explains how the particles loosen their bonds when given energy. Solids become liquids and liquids become solids. 

Find out how matter fits into more than one state with this entertaining video that details non-newtonian fluids and a step-by-step instruction for how to make oobleck. 

What exactly can we tell about an unknown substance by its properties? is the driving question of this physical science video focusing on matter. Here, scholars find the answer to the big question via investigation of what lies...

Get your blocks out! It's time to start building and learning about mass! Enthusiastic chemists get in-depth information about the conservation of mass and the way it applies to chemical changes. 

Your enthusiastic chemists will flip over this entertaining video about matter and its chemical changes! Take an in-depth look into what chemical changes are and the evidence that is observed, such as color, smell, and heat. Then,...

What is matter? Find out in this entertaining video that thoroughly details how matter has both volume and weight, but looks different as a liquid, solid, and gas.

Learn about the states of matter with an entertaining physical science video. With captioned explanations and real-world examples of changes states of matter, the video is an excellent addition to your lesson or homework assignment.

Help young scientists connect the dots between pressure, temperature, and volume with a video on the ideal gas law. After first reviewing the formula for this fundamental law, the instructor walks step by step through nine different...

How can something we can't see be so powerful? Gas molecules make an impact! This video explains their properties: 1. Gas particles always move in a straight line. 2. They are too small to occupy any volume individually. 3. When gas...

Using chalkboard animation, this video thoroughly explains the three empirical gas laws: Avogadro's, Boyle's, and Charles'. Use it as an introduction when teaching young chemists about the properties and behavior of gases.

A teenaged Jack Spangler demonstrates how reducing air pressure in a bottle can pull a boiled egg inside. Then dad does a similar demonstration using liquid nitrogen to reduce the air pressure. Even though the result is the same, the...

Create a cauldron of bubbling fun with this Halloween-themed demonstration idea. Using dry ice, Steve Spangler creates a crystal ball. If you compare the sublimation of dry ice to the melting of water ice, it is a wonderful way to...

In this episode of "Steve Spangler Science" videos, the gas produced by the sublimation of carbon dioxide dry ice creates a nice, fluffy cushion in a bowl of water. Since it is less dense than a soap bubble and cool enough to keep it...

There are four states of matter: solid, liquid, gas, and plasma. As this clip describes, the key to changing the states of matter is the addition or subtraction of energy. Learn about molecules, heat, plasma, and the science behind...

How are gases like liquids; how are they different? This clip demonstrates the state of matter called gas. We find out how the properties of gas are similar and different to the properties of liquid. An experimental demonstration and...

Charles' Law states that the temperature of a gas is directly proportional to the volume. Compressing a gas increases the heat, and giving it more space allows the molecules slow in speed and cool down. The narrator proves this concept...

In this video adapted from the National Science Center, students will observe a demonstration to discover how helium gas is inert and hydrogen gas is reactive. [2:17]

Watch this short video to learn how the ideal gas law is deducted and how to calculate the value of the constant R.

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 the kinetic...

This video segment adapted from ZOOM offers a clever demonstration of buoyancy by showing how to pour a cup of air into a cup filled with water. [1 mim, 42 sec]
