Imploding Pop Can
Source Institutions
In this dramatic activity/demonstration about phase change and condensation, learners place an aluminum can filled with about two tablespoons of water on a stove burner.
Crunch Time
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.
Toasty Wind
Source Institutions
In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.
A Pressing Engagement
Source Institutions
In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.
Does Air Weigh Anything?
Source Institutions
The demonstration/experiment provides quick proof that air has mass.
If Hot Air Rises, Why is it Cold in the Mountains?
Source Institutions
This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside
Turning the Air Upside Down: Convection Current Model
Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.
Go with the Flow
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.
Balloon Inside a Bottle
Source Institutions
In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.
Origami Flying Disk
Source Institutions
In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.
That Sinking Feeling
Source Institutions
In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.
Moving Without Wheels
In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.
Hot Stuff!: Carbon Dioxide Extinguishes a Flame
In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.
Hot Stuff!: Creating and Testing for Carbon Dioxide
In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.
Hot Stuff!: Testing Ice
In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.
Good Vibrations
Source Institutions
This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.
Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.
Heavy Air
Source Institutions
In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.
Test Your Lung Power
Source Institutions
In this activity, learners try to blow up a balloon hanging inside of an empty bottle.
Turning the Air Upside Down: Warm Air is Less Dense than Cool Air
Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.
