Compare and contrast warm and cold fronts
This pair of Earth science animations show students what happens at cold and warm fronts as clouds are formed by the interaction of warm air and cool air. The cool front animation depicts cumulonimbus clouds forming as a cold front moves into a region of warm air and forces the warm air to rise. In contrast, the warm front animation shows how warm air, moving over cold air, causes a progression of nimbostratus to cirrus clouds to form. Movie controls allow students to repeat, pause, or step thro

Ten preparation steps for a successful group presentation
This resource informational piece, part of a series about the future of energy, introduces students to the process of making a successful group presentation. It lists 10 steps for students to follow when making presentations. These include: research and gather information, focus the group's efforts, create a story line, and self-evaluate, among others. Students are given guided questions and checklists for each of the 10 steps to self-evaluate whether they have successfully completed the step. A
Observe images of advection fog
This Earth science resource presents six photographs depicting examples of advection fog along various coastal areas in the United States. The introduction explains how advection fogs form and provides a brief explanation of how they differ from radiation fogs. Students are instructed to click on each labeled image to see an enlarged version of it. Each enlarged version includes a caption that describes the location of the fog relative to local landmarks in the picture. Copyright 2005 Eisenhower
