Procedure: Direct students to their textbooks and online resources to learn about what causes earthquakes and the scale used to measure an earthquake's magnitude. Then, organize students into small groups and assign each group one year between 1999 and 2009. Refer groups to print and online resources to learn more about the most significant earthquakes that took place in their assigned years. On a large map of the world, have students mark (with small circle stickers or markers) the locations of these earthquakes. Based on their observations, have students make hypotheses about why earthquakes occur where they do.

Geothermal energy is opening doors to social and environmental sustainability. CNN's Hugh Riminton reports
Most people have an inkling that if you drilled down to the Earth's core, it would feel pretty hot down there -- around 5,500 degrees Celsius (9,932 degrees Fahrenheit) to be precise, in fact, according to Greenpeace. (Nearer the Earth's surface, however it is a more bearable 10-16 degrees Celsius (50-60 degrees F) all year round.)
Geothermal energy is often considered a clean, sustainable alternative to fossil fuels. However, some raise concerns regarding the environmental impact of the operation due to the significant amount of land needed to harness the energy.
