Solar System Scavenger Hunt
This OLogy activity gives kids a grounded way to understand the scale of the planets in our solar system. The activity begins with a brief overview that tell them why all planets are round and introduces them to the concept that the planets vary widely in size. Kids are then asked to create a model of the solar system using found objects that match the provided scale in inches for the planets. The activity ends with a series of challenges, which include arranging the planets according to size an
Helmut Schmidt became the head of Germany's Social Democratic Party in 1967 and deputy chairman of the party in 1968. Between 1969 and 1972, he served as defense minister, minister for economics and finance, and minister of finance. From 1974 to 1982, he was the chancellor of the Federal Republic of Germany. In this video segment, Schmidt describes what he terms 'Euro-strategic' SS-20 missiles, which the Soviet Union began deploying along its western and southeastern borders in 1977. He viewed t
Radioactive Decay and Absolute Age Determinations
This site provides access to a number of visual resources and supporting material illustrating the concept of radioactive decay and its central role in radiometric dating. Visualizations include diagrams, graphs, static illustrations and photos. Resources found on this site are suitable for use in lectures and classes and may also be used as the basis for labs or other activities.
Your TV Diet
This lesson encourages students to examine their television viewing habits and to assess the impact that watching television has on their life. Students are invited to discuss a basic media literacy concept -- that media industries are driven by commercial interests, that economic factors influence the content of a media product. The lesson asks students to think about how aware they are of this relationship.
Bird watching made elementary

This site presents two dozen publications written in the 19th century about slavery in America. It includes first-person accounts from former slaves, judicial opinions, abolitionist pieces, and more.
The Thomas Jefferson Papers
The complete Thomas Jefferson Papers from the Manuscript Division at the Library of Congress consists of approximately 27,000 documents. This is the largest collection of original Jefferson documents in the world. Document types in the collection as a whole include correspondence, commonplace books, financial account books, and manuscript volumes. The collection is organized into ten series or groupings, ranging in date from 1606 to 1827. Correspondence, memoranda, notes, and drafts of documents
The Northern Great Plains, 1880-1920
This site shows 900 photographs from the Fred Hultstrand and F.A. Pazandak Photograph Collections of rural and small town life at the turn of the century. Highlights include images of sod houses and the people who built them, images of farms and machinery that made them prosper, and images of one-room schools and the children that were educated in them.
