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...

Denver's Brown Cloud - Cool Science Experiment
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...

Dancing Raisins - The Bubble Lifter
Here is an engaging demonstration of density that you can do with your young physical scientists. Place different rough surfaced objects into carbonated liquid. The carbon dioxide bubbles collect on the surface of the objects and...
Curated OER
Balloon Expansion - Sick Science! #038
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.

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...

Sophia Learning
Sophia: Definition of Density: Lesson 1
This lesson will define density as mass/volume and provide relevant real world examples of objects with varying densities. It is 1 of 3 in the series titled "Definition of Density."
Sophia Learning
Sophia: Weight
In this lesson, students are introduced to the concept of weight as the heaviness, or mass and density, of an object. This is the first in a series of lessons about weight. Student watch a video tutorial and then can take an online quiz.
Sophia Learning
Sophia: Weight and Size
In this lesson, students see that an object with a larger size does not necessarily have a larger weight than an object which is smaller in size. This lesson will help students understand the relationship between weight and density....
