Rocks Unit
Picking up, examining and collecting rocks can be the first steps in moving children toward an appreciation of geology and the “bones” of the Earth. Children can find a wide variety of rocks in many places, from the school yard to parks and driveways at home. Even very young children enjoy picking up rocks, lining them up, choosing “favorite” ones, pouring water over them to make them shiny and even painting them as gifts for adults. By letting children handle and observe rocks you give
The Dose Makes the Poison -- Or Does It?
News reports frequently include stories about toxic chemicals in our food, water, and environment. But what does it mean to label a substance either "toxic" or "nontoxic"?
Toxicity indicates the degree to which a substance is poisonous to biological organisms, including humans. The traditional way to test toxicity is to count how many laboratory organisms die or suffer impaired health when exposed to various concentrations of a substance. However, in recent years this method of estimating the d

Persons unknown
Here, the eponymous ones are everyday folk. Frozen in stasis, and caught in seemingly private moments, they are strangely familiar to us despite the emphasis to the contrary suggested by the title. These images have an immediacy which resonates with our universal experience -e.g. discernible feelings of isolation, of insignificance; anxieties and desires.
Often these subjects are pictured by a window. As evidenced by Friedrich's fascination with window-as-motif (which later influenced Rothko)
Effet d'un dispositif de communication médiatisée synchrone dans une tâche de résolution de prob
Cette étude examine l'incidence d'un dispositif de communication médiatisée synchrone (messagerie instantanée) sur les interactions d'enfants de CM1 dans une tâche de co-résolution d'un problème. Les enfants réalisent une tâche de sélection de phrases importantes d'un récit d'abord individuellement puis avec un camarade de classe. Certains enfants collaborent dans une situation de face à face (7 dyades) et d'autres utilisent un dispositif de communication médiatisée synchrone (8 dy

"Conclusions and Recommendations by the Committee of Six Disinterested Americans"
U.S. marines occupied Haiti from 1915 to 1934. By 1919, Haitian Charlemagne Péralte had organized more than a thousand cacos, or armed guerrillas, to militarily oppose the marine occupation. The marines responded to the resistance with a counterinsurgency campaign that razed villages, killed thousands of Haitians, and destroyed the livelihoods of even more. In 1926 the Women's International League for Peace and Freedom (WILPF) organized a committee to look into conditions in Haiti and offer alt
"It Had a Lot of Advantages"Alfred DuBray Praises the Indian Reorganization Act
The Indian Reorganization Act of 1934, which became known as the Indian New Deal, dramatically changed the federal government's Indian policy. Although John Collier, the commissioner of Indian affairs who was responsible for the new policy, may have viewed Indians with great sympathy, not all Native Americans viewed the Indian New Deal in equally positive terms. But in this 1970 interview, Sioux tribal leader Alfred DuBray argued that the Indian New Deal, on balance, brought positive changes.
"Please, Let Me Put Him in a Macaroni Box" The Spanish Influenza of 1918 in Philadelphia
In 1918 and 1919 the Spanish influenza killed more humans than any other disease in a similar period in the history of the world. In the United States a quarter of the population (25 million people or more) contracted the flu; 550,000 died. In the early 1980s, when historian Charles Hardy did interviews for the Philadelphia radio program "The Influenza Pandemic of 1918," he was struck by the painful memories as many older Philadelphians recalled the inability of the city to care for the dead and
