The National Museum of Natural History has a myriad of exciting resources for those who wish to help young people learn about natural history. On the site, visitors can make their way through three sections: Lesson Plans, Web-based Student Activities, and Resources for Teachers & Classrooms. In the Lesson Plans area, visitors can browse resources that include the Ocean Portal, which features lesson plans and fact sheets created by several partner organizations, including NOAA. Also, the area contains a great Measuring Biodiversity Across North America activity which uses state-of-the art interactive mapping technology. The Web-based Student Activities area includes a visually stimulating map titled "This Dynamic Planet" that allows users to explore 1,500 volcanoes, 44,000 earthquakes, and 170 impact craters. The area also includes a wonderful coral reef activity and a great encyclopedia of information of mammals in North America. The last area leads to external links such as the Monterey Bay Aquarium Online Field Guide and the popular AnthroNotes, which contains articles on current anthropological research.
