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.
