This informational piece, part of a series about the future of energy, introduces students to a three-stage process for viewing media. The three stages are preparing, viewing and listening, and reflecting. A student tip sheet explains each stage and enables students to work through the processes in a step-by-step manner while seeing how the information is tied together. Students prepare, examine, and critically summarize their new information. A graphic organizer provides students with an opport
Science Sampler : Weathering database technology
Collecting weather data is a traditional part of a meteorology unit at the middle level, but making connections between the data and weather conditions can be a challenge for students. One way to help students make these connections clearer is to enter the data into a database. This allows students to quickly compare different fields of data and recognize which readings are associated with certain types of weather.
Examine the sun at different wavelengths
This Earth science resource enables students to observe and compare the sun's appearance under different types of electromagnetic radiation. Students are instructed to move the cursor across the spectrum to see images of the sun under radio and microwaves; infrared, visible, and ultraviolet light; and gamma rays. Each image includes a label that indicates the portion of the electromagnetic spectrum, the wavelength in angstroms and meters, and the layer of the sun in view. Copyright 2005 Eisenhow
