The Busy World of Richard Scarry-Imagine That - Mailing Letters
In this video Huckle and Lowly Worm learn about mailing letters. Make sure you have the right address and don't forget the stamp. Letters can be sent anywhere on the map. Someone who delivers mail is called a postal worker. The mail is sorted in order to reach their destination. This is a great teaching resource for the elementary classroom and/or for special education students. This would work well in conjunction with a thematic unit on community helpers. Students will enjoy this video. (1:06)

Let's Heat Things Up!
Students observe demonstrations, and build and evaluate simple models to understand the greenhouse effect, the role of increased greenhouse gas concentration in global warming, and the implications of global warming theory for engineers, themselves and the Earth. In an associated literacy activity, students learn how a bill becomes law and research global warming legislation.
It's Really Heating Up in Here!
Students create and observe a greenhouse effect model and discuss the implications of global warming theory for engineers, themselves and the Earth.
Middle School Portal: Math and Science Pathways (MSP2)
Presented by Scripps Institution of Oceanography, the Earth Like a Puzzle Web site gives a visually interesting and easy-to-follow description of plate tectonics, the geologic theory that explains how the continents and oceans move across the surface of the planet. A highlight of the site, the Recycling Plates page contains an interactive map of the earth, where users can click to view the locations of tectonic plates, spreading centers, and their relationship to volcanoes and earthquakes.

Quarks: Inside the Atom
This video segment adapted from NOVA shows how the particle accelerator helped physicists find parts of the atom even smaller than protons and neutrons.
When Did the First Americans Arrive?
In this video segment adapted from NOVA, recent archaeological evidence leads scientists to revise existing theories about human migrations into the Americas around the time of the last ice age.
Good Neighbors and Bad: Religious Differences on the Plains in the Early 20th century
The harmony of rural life is often romanticized, but differences among neighbors, whether ethnic, religious or political, could often lead to tension, especially as new groups emigrated west. Ezra and Dan Miller were born in a sod house in North Dakota but migrated with a group of Amish Mennonites to Montana. In this 1981 interview, conducted by Laurie Mercier for the Montana Historical Society, they described how local cowboys reacted to the influx of Amish farmers.
Gimme A Break! Mark Twain Lampoons the Horatio Alger Myth
The ideology of success--the notion that anyone could make it with enough hard work--was widely promoted in Gilded Age America. One of its most famous proponents was the author Horatio Alger, whose novels showed how poor boys could move from "rags to respectability" through "pluck and luck." Between the late 1860s and his death in 1899, Alger published more than 100 of these formulaic stories about poor boys who made good more often because of fortunate accidents than because of hard work and de
"We Sang Rock of Ages": Frances Willard Battles Alcohol in the late 19th century
Among the social movements joined and led by women in the late 19th century, including unionization and women's suffrage, none had either the widespread fervor or success enjoyed by the temperance movement. The Woman's Christian Temperance Union (WCTU), founded in 1873, drew widespread support from labor movements such as the Knights of Labor by linking the fight against liquor with the desire to protect home and family against the ravages of the new industrial order. Frances Willard was one of
"We Are Literally Slaves": An Early Twentieth-Century Black Nanny Sets the Record Straight
In folklore the black nursemaid was seen as a dutiful, self-sacrificing black woman who loved her white family and its children every bit as much as her own. Yet the popular images of the loyal, contented black nursemaid, or "mammy," were unfortunately far from the reality for the African-American women who worked in these homes. In 1912 the Independent printed this quasi-autobiographical account of servant life, as related by an African-American domestic worker, which dispelled the comforting "
The Bum as Con Artist: An Undercover Account of the Great Depression
Middle-class observers reacted to hoboes and tramps of the Great Depression with an array of responses, viewing them with suspicion, empathy, concern, fear, sometimes even a twinge of envy. For some, stolidly holding onto traditional values of work and success, the "bum" was suspect, potentially a con artist. Tom Kromer's "Pity the Poor Panhandler: $2 An Hour Is All He Gets" exemplified this stance, urging readers to resist the appeals of panhandlers and refer them to relief agencies, where prof
Slumming Among the Unemployed: William Wycoff Studies Joblessness in the 1890s
Even before the 1890s depression struck with devastating force in 1893, large numbers of jobless men and women competed in tight labor markets and faced homelessness. One of the best first-hand descriptions of "what it is to look for work and fail to find it" comes from political economist Walter Wycoff's two-volume study of The Workers: An Experiment in Reality, first published in 1899. Wycoff had abandoned his studies at Princeton to seek a more concrete appreciation of social problems. His re
This field exercise determines the susceptibility of different rocks to weathering, and, using the dates on the tombstones, estimates some weathering rates. Placing the field lab in context for use, this site describes the learning goals, teaching notes and materials, assessment recommendations, and provides links to other resources and references.
GP-B Educator's Guide
This 52-page booklet provides an overview of the history, science and technology of this mission, including an introduction to Einstein's theory of curved spacetime. The guide also contains 18 pages of hands-on classroom activities related to gyroscopes, curved spacetime, frame-dragging and other concepts related to the GP-B experiment.
This site contains a brief description of the separation mechanism in size exclusion chromatography. The picture helps visualize the separation, but is a simplified and idealized presentation. A companion site, http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/A/AffinityChrom.html, describes affinity chromatography. The two sites together may be helpful in a biochemistry course where such techniques are used or discussed.
