Study Jams! Properties of Matter
Does matter really matter? Properties of matter are discussed by Sam and RJ: mass, volume, and density. They differentiate between mass and weight. They explain how to measure these properties. Make sure to teach your class about other...

Sinking Soda Surprise
I'm sure you've heard that there are something like 20 tablespoons of sugar in a can of regular soda. It seems unbelievable, doesn't it? This demonstration really does show how much sugar is present in a can of soda. First, Spangler...

Denver's Brown Cloud
Why does a brown cloud occur in Denver at a certain time of the year? When warm air is higher in the atmosphere, it traps cooler, denser air below and smog just sits in between them. Using bottles of colored hot and cold water, this...
Curated OER
Balloon Expansion
Have your class explore how a hot air balloon works. Through a simple demonstration, learners can see the process up close, and discuss why this occurs. They can then perform related experiments on their own.

Cosmic Background Radiation, Scale of the Universe, Cosmology and Astronomy
An informative video explains the density of particles immediately after the Big Bang, as well as the concept that whenever a particle was released, it would merge with another particle. Sal develops the concept of being able to receive...

Seven Layer Density - Cool Science Experiment
The densities of a variety of liquids are demonstrated in this simple, yet effective experiment. Liquids such as honey, dish soap, cooking oil, water, rubbing alcohol, and corn syrup are put on top of one another in a large beaker,...

Floating Rice Bottle - Sick Science! #116
More rice grains create more friction. Pack them into a bottle and then you can use a chopstick to pick the bottle up! This is a fascinating demonstration of density and the force of friction.

Egg in a Bottle...The Tricky Way - Cool Science Experiment
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...

Dry Ice Floating Bubble - Sick Science! #058
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...

Amazing 9 Layer Density Tower - Sick Science! #012
This is a strong visual display of density. It requires a mountain of materials and is quite messy, so you most likely will not want to have lab groups perform this activity. You could demonstrate it for your class when exploring the...
