In this lesson, students use observations, activities, and videos to learn basic facts about the Sun. For example, students will understand that the Sun is a star and that its radiation provides Earth with heat and light. Students also model the mechanics of day and night and use solar energy to make a tasty treat. The lesson is divided into three parts and the suggested time for completion is three class periods. Note: registration is required to access the Teachers' Domain website, but at no cost to the user. Grade level: K-4. LINK >> |

This report describes the results of a study in which climate modeling was used to examine the effects of deforestation in the Amazon basin. The study concluded that changes in land surface properties (loss of forest cover) cause changes in the mean surface wind stress in the tropical Pacific, which in turn results in increased variability of El Nino/Southern Oscillation (ENSO) events.

What are red tides? Red tide is a phenomenon caused by algal blooms (Wikipedia definition) during which algae become so numerous that they discolor coastal waters (hence the name "red tide"). This tutorial with educator collections is an excellent introduction with links to further study. [Source: Microbial Life - Educational Resources, M.
