Air, air, everywhere, but what's in it, and what makes Earth's air so unique and special? Journey through the layers above us to uncover our atmosphere's composition and how it works to make life possible below. Pupils conduct...

What is the difference between a comet and a meteoroid? An educational lesson includes five demonstrations of how the atmosphere can inhibit our ability to measure many things in the galaxy. 

Students probe the dynamic weather changes through several hands-0n activities in this seven lessons unit. The hydrologic cycle, clouds, atmosphere, air movement, fronts, and forecasting form the components presented in this unit.

Students explore meteorology, discuss Earth's atmosphere, create drawings of the water cycle, create meteorology journals, and role play forecasters. Nine lessons on one page; includes unit test.

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Watch and learn with Bill Nye the Science Guy while exploring concepts such as atmospheric pressure, and combustion chemistry by manipulating gases and air. [1:37]

[Free Registration/Login may be required to access all resource tools.] Atmospheric pressure and how it changes with increasing altitude, and how air pressure is used.

An explanation of the different parts of the atmosphere and how pressure and temperature changes at different altitudes.

[Free Registration/Login may be required to access all resource tools.] Student learn how atmospheric pressure is measured and what is meant by gauge pressure.

Instructional module focusing on Earth's atmosphere. Discussion includes major components, layers, air pressure, and scientific monitoring of the atmosphere. Site also includes an interactive practice quiz and links relating to the topic.

In this unit, students learn the basics about weather and the atmosphere. They investigate materials engineering as it applies to weather and the choices available to us for clothing to counteract the effects of weather. Students have...

Earth and its atmosphere have provided us with air to breathe, water to drink, and food to eat, but these are not the only requirements for survival. Although you may rarely think about it, you also cannot live outside of a certain range...

This online lecture covers topics of air pressure, density and temperature.

Discover the effects of water vapor, the form water takes on as a gas, when it undergoes changes in atmospheric pressure as Bill Nye the Science Guy provides a demonstration of the compound water.

A suite of lessons focusing on the basic elements of climate and weather. Inquiry-based exploration of extreme weather events and the factors of weather including clouds, wind, air pressure, temperature, and the water cycle.

Mars has such low atmospheric pressure that any water at the surface would boil away. In this activity, students see that they can get water to boil below its "typical" boiling temperature when they drop the pressure in a closed...

Students learn about exponential functions, logarithmic functions, and applications of exponential functions. The tutorial includes class notes, calculator tips, examples, and practice problems with solutions. The teacher resource...

A detailed overview of the Earth's climate, with explanations about the difference between weather and climate, dendrochronology, palynology, and how Earth's climate has changed over time. All information is reinforced through pictures,...
