Students observe the process of cloud formation in this demonstration activity using a rectangular pan, small glass, large rectangular pencil eraser, water and a few grains of salt. In a closed system, water vapor floats inside the glass until it... (View More)

This article discusses how the Multi-angle Imaging SpectroRadiometer (MISR) instrument found on the Terra satellite is used to understand how particles in the atmosphere interact with sunlight and how particle pollution affects Earth's climate.... (View More)

Learning cloud terminology is supported by this activity where students use cotton balls and construction paper to create cirrus, cumulus, and stratus clouds. A cloud chart and altitude chart are provided for use by students. The resource is part of... (View More)

In this activity, students model the water cycle using a set of glass bowls, water, salt, clear plastic wrap, and a marble. and observe the process of evaporation, condensation, and precipitation. They observe that water can change from a liquid to... (View More)

This demonstration allows students to visualize how heat moves through convection - using water, food coloring, a small cup and a large jar - and prompts them to make a connection between the observed process and cloud formation. The resource is... (View More)

In this demonstration, students learn that air flows from a high-pressure area to a low pressure area, and greater the differences between pressure areas, the greater the wind speed. The demonstration uses an apparatus made from two 2L beverage... (View More)

In this demonstration, relative humidity is modeled using a sponge and a pan of water, and the concept of saturation is depicted. Students answer questions examining the relationship between temperature and the capacity of air to hold water vapor.... (View More)

In the culminating activity of this investigation, students write an editorial entitled, Are We Warming Earth?, in which they attempt to persuade readers to take global warming seriously. Leading up to that activity, students read background... (View More)

El Niño Southern Oscillation (ENSO) affects weather, climate, and, consequently, humans and their activities. In this investigation, students review and analyze ENSO background info, data and satellite images in preparation for a game. Acting as... (View More)

This investigation introduces students to the phenomena of urban heat islands, areas of higher then normal temperatures associated with populated areas. Using Atlanta, Ga., as the study site, students begin by analyzing the population growth and... (View More)
