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.

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

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...

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.

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...

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.

Students are introduced to the concept of air quality by investigating the composition, properties, atmospheric layers and everyday importance of air. They explore the sources and effects of visible and invisible air pollution. By...
