This series of 5 high-quality, standards-aligned, inquiry-based lessons have been field-tested by the fifth grade students of Wequiock Children's Center for Environmental Science and their teachers. These lessons encourage students to use natural areas around their school as they improve their science and engineering skills as part of a unit on earth's systems. Created as a part of a WISELearn OER Innovation project, Connect, Explore, and Engage: Using the Environment as the Context for Science Learning was a collaboration of the Wequiock Children's Center for Environmental Science and the Wisconsin Green Schools Network. One of the goals of the project was to create standards-aligned lessons that utilize the outdoor spaces of the school . These lessons were created to take place during late winter. A stewardship project to reduce the impact of stormwater run-off was planned for the spring.

This video segment, adapted fromThinking Big, Building Small, demonstrates each part of the engineering design process, which is fundamental to any successful project. Though it does this in the context of building skyscrapers, the process is applicable to any sort of project, including constructing schools, building bridges, and even manufacturing sneakers. Students will recognize the value of going through its steps sequentially when constructing scale models. Recommended for: Grades 3-12

In April 1940 Secretary of Labor Frances Perkins convened a conference in Missouri concerning the silicosis crisis that had emerged in the late 1930s. The differing perspectives on the disease and workers' health are apparent in these excerpts from the Tristate Silicosis Conference. Evan Just, representing industry, claimed that silicosis is a social, not an industrial, problem. Ex-miner Tony McTeer disputed Just's analysis, arguing that he, himself, contracted silicosis even though he had worked only in mines that employed the improved "wet drilling" method. The legendary public health advocate Dr. Alice Hamilton, representing the Public Health Service, spoke on the medical aspects of industrial hygiene and showed that, despite industry's claims, little had improved over the past twenty-five years.

You are employees of competing water testing companies. You recently received a request from the municipality of Cavour to test their water for an unknown/suspected parasite that they suspect has been causing nausea and intestinal distress in their community.

Your mission is to develop the proper Method for testing for the parasite and provide a detailed lab report.

An interview with biologist Gro Amdam, one of the members of the group that brought us the bee genome. Hey just what is a genome and could bees hold the answer to aging? In this show we learn the answers to these questions and why researchers are buzzing around bees.

Racism remained potent in the 1920s, but ideas about race were changing, particularly among intellectuals. Almost without exception, social scientists and scholars in the 1890s assumed that race was one of the central ways of understanding human beings. But a profound change in American thinking occurred in the first two decades of the 20th century. A new philosophy, that today might be termed "cultural relativism," began to influence American intellectuals and their students. The emergence of this philosophy in the U.S. owes a great deal to Franz Boas, a German-Jewish anthropologist who taught at Columbia University from 1896 through the 1930s. In this essay, "The Instability of Human Types," delivered at an academic conference on race in 1911, Boas boldly argued against assumptions of innate racial inferiority; insisting that culture, not nature, explained differences among the people of the world. Boas's students included the anthropologist Margaret Mead and the writer Zora Neale Hurston.

Those who built the atomic bomb at the secret Los Alamos, New Mexico, facility understood very well the potential for destruction and death they had created, though individual reactions of the scientists varied widely. Some argued that America needed to develop nuclear weapons before the Germans did. Others argued that a war against fascism demanded the most lethal measures. Still others, as they witnessed the blast on July 16, 1945, were appalled at what they had unleashed. In this excerpt from a 1980 interview, Bernard Feld recalled his work as a graduate student at Los Alamos. While he had few reservations about the bomb's development and its first use at Hiroshima, he had profound reservations about using the second bomb against Nagasaki.

Despite a space with limited possibilities, Becky Smith has organized a high school biology classroom where she can work and her students can learn. A classroom profile.

Plastics can be shaped easily and are used for many functions, making them extremely popular across the world. However, most plastics negatively impact the environment and some can take thousands of years or longer to break down. Scientists are testing new ways to make plastics that are biodegradable so they can be decomposed and won’t last as long in the environment. How can researchers use knowledge about the chemical properties of different monomers to make alternatives for synthetic plastics?

Students learn about an astrophysicist that is working in science to open possible ideas for themselves in science careers. Pursuits addressed: Identity-Students will learn about people who they can relate to who are currently working in STEM related careers and study possible STEM related careers that could be meaningful to their own lives/cultures.Skills-The students will research scientists who they can relate to culturally who are working on STEM related careers and then write letters to these scientists in a way that is interesting, genuine, authentic, and allows them to use their own voice.Intellect-Students will choose which scientists they would each like to study by finding scientists who they can relate to culturally who are currently working in STEM related careers and showing examples of Black Excellence.Details: This lesson can be added to 5th Grade Amplify Patterns of Earth and Sky: Analyzing Stars on Ancient Artifacts, with Lesson 2.1 after looking for patterns, making observations, and reflecting on the Model. Explain to the students that this is exactly what astrophysicists do.

Photographers covered the Civil War, following the Union Army in wagons that served as traveling darkrooms. Their equipment was bulky and the exposures had to be long, so they could not take action photographs during battle. But photography was graphic; this picture taken on the morning of July 4th, 1863 after three days of heavy fighting during the Battle of Gettysburg, showed the northern public that dying in battle lacked the gallantry often represented in paintings and prints.

In the 1820s, operatives in the Lowell cotton mills, mostly women, worked twelve hours a day, six days a week. Holidays were few and short: July Fourth, Thanksgiving, and the first day of spring. In the 1830s, with increased competition, conditions worsened as owners cut wages, raised boarding house rents, or increased workloads. To protest these changes, women went out on strike in 1834 and 1836. This promotional engraving showed a mill woman standing in unlikely repose beside a Fale and Jenks spinning frame. The benign relationship of the figure to the machine may have served to reassure nineteenth-century observers that factory work would not debase virtuous womanhood.""
