This collection uses primary sources to explore twentieth-century mining in the Mojave Desert. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

This inquiry examines the 20th century history of migration from Mexico to the United States and recent efforts to limit the movement of people across the southern U.S. border. The inquiry takes its inspiration from a 2018 podcast episode by Malcom Gladwell titled, “General Chapman’s Last Stand.” The podcast is part of Gladwell’s Revisionist History series (http://revisionisthistory.com). In the podcast, Gladwell tells the story of General Leonard F. Chapman Jr., Commandant of the Marine Corps during the Vietnam War, who went on to serve as the Commissioner of the Immigration and Naturalization Service (INS) from 1972 to 1975. Chapman is credited with reforming the INS into a more efficient and effective agency, but Gladwell argues that Chapman’s efforts also led to an unintentional increase in unauthorized immigrants. In 1970, 760,000 Mexican immigrants, or 1.4% of Mexico’s population, lived in the U.S. By 2008, there were 12.7 million Mexican immigrants in the U.S. which amounted to 11% of all people born in Mexico; an increase of almost 800% in less than 30 years. The question of how and why this happened is the central focus of this inquiry.

The British soldiers have long been blamed for firing upon innocent colonists the night of the Boston Massacre.  Students will examine primary and secondary sources to determine if the soldiers indeed attacked innocent colonists or were acting in self-defense against an angry mob. This inquiry asks, “Did the British soldiers open fire on innocent colonists at the Boston Massacre?”  Resource created by Michelle Wittstruck, Milford Public Schools, as part of the Nebraska ESUCC Social Studies Special Projects 2022 - Inquiry Design Model (IDM).

Students will analyze a picture of Paul Revere's Engraving and answer some guided photo analysis questions. 

Boston Sports Temples celebrates the rich histories of Boston’s professional stadiums and arenas. Some, like Fenway Park, still welcome fans today. Others were demolished decades ago, leaving only hints of their former glory amid the urban landscape. This exhibition welcomes modern fans through the gates of venues both famous and forgotten: the various home fields—and courts and tracks and ice—of Boston’s most beloved franchises and hosts to a century of public events, concerts, and gatherings. Featuring historical photographs from the Boston Public Library’s extensive archives, Boston Sports Temples draws from thousands of negatives and prints dating from the early twentieth century through the 1960s. The images capture the unique character of Boston’s historic sports venues, memorable moments, and the communities of athletes, fans, and staff who have come together within their walls. Together, these vintage materials provide an invaluable window into the past and a nostalgic look back at our city, our deep sporting traditions, and generations of passionate fandom. Created by the Boston Public Library.

This collection uses primary sources to explore the Boston Tea Party. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

By exploring historical accounts of events surrounding the Boston Tea Party, students learn about the sources and methods that historians use to reconstruct what happened in the past.

This list of botanical gardens and arboretums includes links to Web sites which you can search for institutions in your region. In addition, it includes detailed information about 14 of the country's largest botanical gardens and arboretums. Where possible, it includes the following information for each: mailing address and phone number, Web site and email address, details about its grounds and collections, and the type of support offered, including educational materials, resource libraries, and classes/workshops.

Los estudiantes diseñan y construyen un bote de arcilla que puede soportar peso.

Experiment with rocket designs and a PVC launcher to discover how high—and how far—you can make your rockets go.

Here’s a new “spin” on an old toy. In this modern adaptation of a classic toy—the spool racer—a plastic water bottle is propelled by energy stored in a wound-up rubber band.

Students examine how different balls react when colliding with different surfaces, giving plenty of opportunity for them to see the difference between elastic and inelastic collisions, learn how to calculate momentum, and understand the principle of conservation of momentum.

In this activity, students examine how different balls react when colliding with different surfaces. Also, they will have plenty of opportunity to learn how to calculate momentum and understand the principle of conservation of momentum.

Students become product engineers in a bouncy ball factory as they design and prototype a polymer bouncy ball that meets specific requirements: must be spherical in shape, cannot disintegrate when thrown on the ground, and, of course, must bounce. Along with these design elements, students can build (with teacher assistance) a “shadow box” that helps measure the contact angle of the polymer that provides data on how to iterate. In addition, students must consider the aesthetics of their bouncy balls for customer approval and marketing purposes. Using the engineering design process, students design and create bouncy balls from polymers to create a fun, exciting toy for children.

Students find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped box from the original box material, students discover that the cubical box has less surface area than the original, and thus, a cube is a more efficient way to package things. Students then consider why consumer goods generally aren't packaged in cube-shaped boxes, even though they would require less material to produce and ultimately, less waste to discard. To display their findings, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved. The activities involved provide valuable experience in problem solving with spatial-visual relationships.

To display the results from the previous activity, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved. They problem solve and apply their understanding of see-saws and lever systems to create balanced mobiles.
