A Recipe for Air
Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

I Can't Take the Pressure!
Learners develop an understanding of air pressure in two different activities.

What Color is Your Air Today?
Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

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.

Hot Air
Source Institutions
In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

Air-filled (Pneumatic) Bone Experiments
Source Institutions
Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

Yeast-Air Balloons
Source Institutions
In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

Good News: We're on the Rise!
Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

Hot Stuff!: Testing for Carbon Dioxide from Our Own Breath
Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into 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.

Acid (and Base) Rainbows
Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

Acid Rain Effects
Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

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.

Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.
Coat Hanger Chimes
Source Institutions
In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.

Decibel Cannon
Source Institutions
In this activity, learners will construct an air cannon as a model for the human ear.

Metal Noise Maker
Source Institutions
In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.

Soap Bubble Art
Source Institutions
Capture soap bubble patterns on paper! In this activity, learners can create beautiful pictures from popping soap bubbles.

On the Fringe (formerly Bridge Light)
Source Institutions
In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

Photosynthesis and Transpiration
Source Institutions
In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.
