Relates to the linked video, DragonflyTV: Forecasting.

This is a series of activities demonstrating that air has mass, takes up space, and can exert a force on objects enough to lift them.

By watching and performing several simple experiments, students develop an understanding of the properties of air: it has mass, it takes up space, it can move, it exerts pressure, it can do work.

Air pressure is pushing on us all the time although we do not usually notice it. In this activity, students learn about the units of pressure and get a sense of just how much air pressure is pushing on them.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment. In this modern, low cost version, a pair of learners try to pull apart two suction cups (dent pullers). Learners then calculate the amount of force holding the dent pullers together.

This is an inquiry activity that relies of pervious understanding of balancing and weighing to introduce a properties of air.

Students are introduced to air masses, with an emphasis on the differences between and characteristics of high- versus low-pressure air systems. Students also hear about weather forecasting instrumentation and how engineers work to improve these instruments for atmospheric measurements on Earth and in space.

Let's imagine a scale model of the Earth and use a basketball to represent the Earth. Now, let's get ourselves some packages of fruit roll-ups and start covering the basketball with layers of fruit roll-ups. How many layers would we have to cover the basketball with in order to make the stack of fruit roll-ups as thick as the Earth's atmosphere, to scale?

Air is our most precious resource. Without food, we can live for weeks and without water, we can live for days. But without air to breathe, we survive about 4 minutes! If you visit the top of Mt. Lemmon in Arizona, you will probably notice a shortness of breath due to the thinner atmosphere at 8,000 ft. At the top of Mt. Everest at 29,000 ft. about 99% of the earth's atmosphere is below you. In a commercial jet, traveling across country, you would be dead in minutes without the pressurized cabin and supply of oxygen to breathe.Relative to the planet earth, the atmosphere we survive in is extremely thin. Most people live at or close to sea level since most of the major cities of the world are along coastlines. Some cities and villages in Mexico, South America and China are at higher elevations from 8,000 to 12,000 ft. Few, if any, people actually live above 15,000 ft. Mt McKinley in Alaska is about 20,000 ft high and climbers do get to the top without oxygen tanks but they need tremendous determination due in part to the thin atmosphere.Given that most people live below an altitude of 15,000 ft., calculate the thickness in miles of the atmosphere in which humans effectively live.

Using gumdrops and toothpicks, students conduct a large-group, interactive ozone depletion model. Students explore the dynamic and competing upper atmospheric roles of the protective ozone layer, the sun's UV radiation and harmful human-made CFCs (chlorofluorocarbons).

In this quick activity (page 1 of PDF), learners will witness firsthand the effects of Bernoulliäóťs Principle by capturing a ping pong ball in the stream of air created by a hair dryer.
