Created by Professor Herr at California State University-Northridge, the Sourcebook for Teaching Science offers a trove of materials for science educators in the fields of biology, chemistry, physics, and the geophysical sciences. This corner of his site brings together resources for teaching meteorology from a vast litany of institutions, including NOAA, the National Science Foundation, and National Geographic. The materials are divided into five areas, including The Atmosphere, United States Weather, and Teaching Resources. This last area is quite useful as it contains databases of lesson plans, a set of exercises dealing with the Northern Lights, and more. Visitors are encouraged to look around at other general resources offered here, such as the worksheets on developing a scientific vocabulary and the importance of organizing scientific information.
