The American Society of Mammalogists
Founded in 1919, the American Society of Mammalogists (AMS) is an organization, composed primarily of professional scientists, that promotes mammal study. The members of AMS also work to provide "information for public policy, resources management, conservation, and education." A notable ASM site feature is the Mammal Image Library which provides "images of mammals for educational purposes worldwide." The ASM website also contains information about two main publications, _The Journal of Mammalog
Earth Today: A Digital View of our Dynamic Planet
Earth Today: A Digital View of our Dynamic Planet is offered by the Smithsonian Institution's National Air and Space Museum and is described as a "state of the art digital theater that's updated several times daily to show near real-time satellite views of the Earth's atmosphere, oceans, and landmasses." The Our Dynamic Earth section contains several topics, such as The Atmosphere, in which users can read about the subject and see impressive satellite images and animations of Earth from space. T
General Electric Company: Innovation Timeline
Now over 110 years old, General Electric played an important role in the worldwide adoption of many modern technologies. The company maintains this timeline of events and innovations that happened since its formation. Beginning with Thomas Edison's carbon filament lamp in 1879, the timeline briefly describes each entry and its significance. A picture and the occasional video clip are also included. While some of the material pertains to GE history, it mainly represents technological progress mad
Founded in 1936, the Herpetologists' League (HL) "exists to promote scientific study and conservation of amphibians and reptiles. The primary goals of the League are to support the acquisition of knowledge about these organisms, and to transmit that knowledge through publications, conferences, and symposia." Hosted by the Illinois Natural History Survey, the HL website contains contact information for current League Officers, as well as information about membership, and the upcoming Joint Meetin

Ozone in the atmosphere : ozone depletion
What processes cause a depletion of the ozone layer? This informational page, part of an interactive laboratory series for grades 8-12, explores natural and human-made destruction of the ozone layer. Here students read about the instability of ozone atoms and the naturally changing quantities of ozone in the air. Volcanoes, the oceans, and other natural processes provide chemicals that break down ozone. Chemical equations of the breakdowns are provided. A discussion of the use of chlorofluorocar
A Map of Things To Come : National Geographic Map Lesson
This lesson will enable students to analyze and interpret mapped information regarding the effects of urban sprawl on Maryland, and state government efforts during the past decade to address it. The lesson includes two activities based on urban sprawl and a smart growth map.

Golden rectangle (grades 6-8)
This virtual manipulative can help students visualize the golden rectangle. It shows how a set of golden rectangles is generated by using the golden ratio (the ratio of the longer side to the shorter side of a golden rectangle) to create smaller golden rectangles within an initial rectangle. The size of the initial rectangle can be varied, and the center of the spiral generated by the applet can be seen. Instructions for using this online manipulative are included on the site, as is a link to th
Quilt blocks: geometry with a cultural warmth
This lesson describes how quilting activities can be used to integrate geometry and lessons about various cultures into the classroom. Suggested ways of creating paper quilt blocks include Hawaiian techniques, where many different blocks are brought together to make a quilt; Amish techniques, where shapes are pieced together in an intricate pattern; and African techniques, which have an emphasis on strip textiles made on hand looms and religious symbols. The geometric concepts of symmetry, tilin
