Understanding the significance of the U.S. Constitution requires more than simply reading its text. This website provides context and tools designed to historically contextualize the U.S. Constitution and help users assess its lasting impact. An interactive Constitution lies at the heart of the website, providing line-by-line commentary by current scholars alongside excerpts from contemporary primary sources. Users can also search the Constitution in connection with specific court cases, topics, and keywords.

An interactive timeline in the exhibit "Centuries of Citizenship" provides useful background information. Additional contextual information is available in the form of a set of "fast facts"; descriptions of "basic governing principles," such as the rule of law, Federalism, and judicial review; detailed biographical information on all delegates to the Constitutional Convention; and audio discussions with scholars and pundits on topics ranging from voting to prominent court cases to women in the Early Republic. Three scholarly essays provide different "perspectives on the Constitution," reminding users that the success of the Constitution in uniting a group of diverse territories was far from assured in the late 1700s. Related primary sources in the "Founding Documents" section allow users to trace the relationship between the U.S. Constitution and the Magna Carta, the Mayflower Compact, and the Virginia Declaration of Rights.

New editions include the interactive experience "Lincoln's Crossroads," in which students face some of the choices Lincoln faced during his presidency; "A More Perfect Union," an exhibit on Barack Obama's 2008 speech on race at the Constitution Center; " and "Seize the Vote," a 4-player game testing voting rights' knowledge.

The Sewall-Belmont House is a National Woman's Party-run museum on women's equality movements in the U.S. A portion of their collections are now searchable online.

Using the site's search engine, you can easily find printing blocks for the newspaper the Suffragist, as well as cartoons by Nina Allender. Other items may be a bit more difficult to find, but the collection includes keys, voting cards, a jail door pin (worn by suffragists jailed for their activism), and more.

If you aren't sure what to look for, try either Click and Search or a selection of Random Images. Each time you access the images, a different set will be pulled from the collection. As for "click and search," you can choose a letter for any of an object's data fields (object type, creator, subject, etc.), and browse through corresponding drop-down lists. Select anything that catches your eye, and the site will bring you to that particular artifact's page.

Among these three ways of accessing the site content, you should be able to uncover a treasure trove of women's rights sources to share with your classroom.

This website gathers together documents concerning the history of National Park Service properties.

Navigation is simple. Just select your park of interest from the drop-down list, and you will be brought to a list of all of the available documents for that particular location. Documents include structure reports, administrative histories, physical and cultural landscape reports, studies of historic resources available, management regulations, conference proceedings, notes, and more.

Note that these resources largely explore the history of preserving a historical site, rather than the importance of the site itself. This is the history of making history public. The documents are most likely to be of use in the later grades, as they lean towards official language. However, there are also images such as floor plans and photographs within documents which may be of use when introducing a park into your discussions.

The Lincoln-Douglas Debates of 1858 website covers precisely what it sounds as if it would—the famed debates between senatorial candidates Abraham Lincoln and Stephen Douglas.

Navigation is simple, divided into sections by primary source type. Debate Text from Nicolay and Hay< includes "transcriptions" of the debates recreated by two of Lincoln's secretaries circa 1894, as well as debate-related publications by the same two individuals. The transcriptions are based on Lincoln's own writings and newspaper accounts of the debates. Debate Text from Newspapers provides links to newspaper versions of the debate. The website notes that newspapers were affiliated with a political party, and that it can be intriguing to compare Democratic and Republican accounts of the same speech. Debate Commentary from Newspapers is similar to the newspaper debate text section except that it covers period observations on the debates rather than the words spoken.

Additional sections contain video commentary on the debates, maps, relevant images, and two lesson plans. Note that the lesson plans do not specify appropriate grade levels.

The Center on Congress, led by former U.S. Representative Lee Hamilton, exists to help the public better understand the role of Congress and the public's relationship to it. Their audience includes the general public, teachers, and journalists.

Your first thought as an educator may be to click on Teacher Resources. However, this section is more of a gateway to content in Learn About Congress than a section unto itself. That said, Classroom Resources does include a tool for paring down the site's educational materials to the appropriate grade level and topic, as well as best practices videos of lessons in action.

Learning About Congress has the widest variety of content useful to the K-12 educator. Resources include approximately 8 interactive modules, more than 20 short animated videos, a collection of live-action video clips of "insider views," more than 30 brief audio presentations on issues ranging from disaster relief to bilingual education, and a variety of relevant reading material. The spoken narration on the interactive modules tends to be dry, and would more than likely only be of use in the higher grades. However, the animated videos are enthusiastically narrated, making them more appropriate for a wider range of viewers. A free Citizen's Guide helps to connect daily life to the actions of Congress. The guide is not unlike a textbook in terms of language and graphic design. As such, its format should be readily accessible and familiar to the average student.

Depending on your computer access and comfort with online activities, you may also be interested in the Virtual Congress where your students can create members of Congress, move their avatars through digital recreations of key locations, and participate in a "multi-player" setting proposing legislation. Another option is Teaching with Primary Sources, a joint effort between the Center on Congress and the Library of Congress, providing separate entry points for teachers and students. These offerings require free registration.

Other items of interest on the site include results of public and political scientists' surveys on Congress' function, beginning in 2002; a blog concerning topics relevant to current Congressional issues; and Congressional FAQs. Teachers can also apply for the American Civic Education Teacher Awards.

In 1868, Laura Jernegan, six-year-old daughter of a whaling captain, put to sea with her parents and younger brother. This website, created by the Martha's Vineyard Museum, explores her family's four-year whaling expedition, focusing on Laura's own diary.

Two narratives ground the exhibit: "The Story of Whaling" and "Laura's Story." Each narrative is divided up into three sections—"Before the Voyage," "The Voyage" and "After the Voyage"—and consists of 14—15 individual "chapters," each a short essay of approximately 300—1600 words. "The Story of Whaling" describes the rise and fall of the whaling industry and the nature of a whaling voyage, including preparation and hiring crew.

"Laura's Story" narrates the voyage of the Roman, the ship on which Laura and her family set sail. The voyage included a stay in Hawaii, mutiny, and the Roman's sinking in the Arctic (everyone survived). "Laura's Story" also looks at the lives of Laura and her family before and after the voyage, as young children and as adults. Each essay include links to images, descriptions, and other sections of the website that clarify and enrich the text.

For Laura's own description of her time at sea, "Explore Laura's Journal" lets visitors browse her 43-page journal. Written in a child's bold handwriting, the journal is short and easy to read, and can be viewed in the original scans, as a text transcript, or with a magic lens feature that translates the writing into print as the mouse runs over a page.

Further background information supports the two narratives and Laura's journal, including:

• "About Whales," a mini-exhibit answering basic questions about six whale species;
• an interactive timeline reaching from 1774 to 1955, including both general world history events and whaling events;
• "Explore the Ship," a diagram of a whaling ship that visitors can click for information on crew positions and parts of the ship; and
• a "Map of Whaling."

This interactive world map lets visitors display features from six sets of information, turning each set on or off and overlaying them. The sets include the four routes of the Roman's journey, three typical whaling routes, posts and sites important to whaling, 1878 whaling grounds for four species, major ocean currents, and whale migration patterns for three species.

Finally, visitors can view zoomable photographs of 175 different whaling-related objects in "Artifacts," read the descriptions of 15 crew positions in "Meet the Crew," and browse 16 pieces of logbook art, 36 photos, and 53 whaling-related images in the "Picture Gallery." An A-to-Z glossary offers definitions for 180 historical and whaling terms. Visitors can also explore the biographies of five people, including all of the members of the Jernegan family and, in "More About," can read 10 more 1,000-3,000-word essays on subjects like race and whaling, women and whaling, and 19th-century children's literature.

In the "For Teachers" section, educators can download two units on whaling: a four-lesson unit for grades 1–3, or a six-lesson unit for 4–5. "For Further Study" features a bibliography of 75 books for children and adults and eight annotated links.

A thorough website centered around a very unique primary source—use it to invite young children into history through the voice of a peer!

Created by the Library of Virginia as part of its Virginia Memory project, this website lets visitors explore the events leading up to and immediately following Virginia's secession from the Union on April 17, 1861. Short essays and more than 200 primary sources, including newspaper articles, speeches, letters, prints and drawings, official documents, maps, and other materials, present the story from a variety of perspectives, including those of women, African Americans, and people both pro- and anti-secession.

The website is divided into six different sections, each providing a different way of approaching the content. “Virginians Decide” divides Virginian history from the beginning of 1860 to July 1861 into 12 chronological sections, covering events including the 1860 presidential election, the meeting of the Virginia Convention of 1861, the formation of West Virginia, and the entrance of Virginia into the Civil War. Each section features a 300–500-word essay introducing the topic, accompanied by 5–45 related primary sources, links to the biographies of related historical figures, and 1–3 more short essays looking at aspects of the topic in greater detail. “Explore” lets visitors search all of the site's primary sources by 11 themes (Business and Economics, Convention of 1861, Elections and Politics, Journalism, Making West Virginia, Military, Restored and Loyal Government, Secessionism, Slavery, Unionism, Women) and seven geographical regions.

Visitors can get to know more about the people in the sources in “People.” Forty 400–2,500-word biographies give overviews of the lives of journalists, members of the Convention of 1850–1851 and of 1861, members of the Wheeling Convention, politicians, ministers, escaped slaves, free black businessmen, writers, army officers, slave traders, and others. Each biography includes related primary sources and links to related biographies. “Timeline” lets visitors browse sources arranged on an interactive timeline covering 1849 to 1862, and “For Educators” includes four downloadable lesson plans (on John Brown and the Fugitive Slave Law).

Of special interest to educators is “Callie's Mailbag.” This section gathers together 22 letters sent to a young educated Virginian woman, daughter of a secession-sympathetic Campbell County family. Callie Anthony was in her early 20s when she received these letters, which date from Dec. 1859 to Jul. 1861 and come from relatives and friends, expressing a wide range of pro- and anti-secession views.

Scanned documents and images can be downloaded in high resolution, and transcripts of written and printed documents are also downloadable. A valuable site for anyone teaching Virginian Civil War history, or wanting to give students a closer look at tensions in a seceding state.

A project of the Library of Virginia, this website makes many of the library's resources available to the public in digital form. Most resources in its digital collections relate to Virginia history, making this a treasure house for educators teaching Virginia state history.

"Digital Collections" contains the bulk of the site's content. More than 70 collections document aspects of Virginian life and politics from the colonial era to the present day, and include photographs, maps, broadsides, newspaper articles, letters, artwork, posters, official documents and records, archived political websites, and many other types of primary sources.

Topics include, but are far from limited to, modern Virgina politics and elections; the 2007 Virginia Tech shooting; World War II photographs; Works Project Administration oral histories; the 1939 World's Fair; World War I veterans and posters; the sinking of the Titanic; stereographs; the Richmond Planet, a 19th-century African American paper; Civil War maps; official documents related to Civil War veterans; religious petitions from 1774 to 1802; letters to the Virginia governor from 1776 to 1784; Dunmore's War; and official documents from the Revolutionary War. Collections can be browsed by topic and title, and are internally searchable using keywords and other filtering tools.

Other features on the site include the "Reading Room," "Exhibitions," and "Online Classroom." "Reading Room" lets visitors explore a primary source for each day in Virginia history or browse a timeline of Virginia history. There are eight essays on unusual sources in the library's collection as well as on new finds in the library's blog, "Out of the Box."

"Exhibitions" preserves 25 exhibits on Virginia history topics that accompany physical exhibitions at the library. "Online Classroom" orients teachers to the site with a short "Guide for Educators," suggesting possible uses for the website's resources, and offers four source analysis sheets and 30 Virginia-history-related lesson plans, all downloadable as .pdfs. The section also highlights two online exhibits designed to be particularly useful to teachers: "Shaping the Constitution," chronicling Virginians' contributions to the founding of the country, and "Union or Secession?", which uses primary sources to explore the months leading up to Virginia's secession in the Civil War.

An invaluable resource for educators covering Virginia state history, this website should also be of use to teachers covering the colonial period, the American Revolution, and the Civil War generally, among other topics.

Created by the nonprofit organizations Rethinking Schools and Teaching for Change, the Zinn Education Project works to bring resources exploring the “role of working people, women, people of color, and organized social movements in shaping history” into the classroom. Inspired by the work of historian Howard Zinn, author of the popular A People's History of the United States, the website provides teachers with materials for expanding on these historical narratives.

“Teaching Materials” contains the bulk of the site's content, including more than 100 teaching activities. These can be downloaded in PDF form following free registration, and include essays, articles, interviews, and full lesson plans on topics related to marginalized groups and labor history. Titles range from “Exploring Women's Rights: The 1908 Textile Strike in a 1st-grade Class” to “What the Tour Guide Didn’t Tell Me: Tourism, Colonialism, and Resistance in Hawai'i”.

“Teaching Materials” also contains more than 300 annotations on audio resources, fiction and nonfiction books, films, posters, commercial teaching guides, websites, and Spanish/bilingual resources. Annotations consist of 2–3 sentences describing the resource and its relevance to Zinn's focus and classroom use.

“Teaching Materials” can be browsed by date (either selected on a timeline, or chosen from 16 time periods, ranging from “Colonialism” to “20th Century” ) or searched by one of 29 themes, five reading levels, or by type of material (teaching activity .pdfs, audio, books: fiction, books: nonfiction, films, posters, teaching guides, websites, or Spanish/bilingual).

Useful to teachers wanting to expand on the traditional textbook narratives on marginalized groups and labor history.

The Presidential Timeline curates and presents primary sources drawn from twelve Presidential Libraries and Museums, institutions housing and presenting archival materials for the presidents from Herbert Hoover to Bill Clinton. Under "Interactive Timeline," you can choose any of the 12 presidents—Herbert Hoover, Franklin D. Roosevelt, Harry S. Truman, Dwight D. Eisenhower, John F. Kennedy, Lyndon B. Johnson, Richard Nixon, Gerald Ford, Jimmy Carter, Ronald Reagan, George Bush, or William Jefferson Clinton—and explore his life.

Timelines consist of at least two sections: "Early Life and Career" and "Presidency." All timelines except Roosevelt's, Kennedy's, and Clinton's also include a "Post-Presidency" section. Marks on the timeline indicate events of interest in the president's life and career; click on a mark to read a brief summary of the event, and to view primary sources (a + sign in the mark indicates primary sources are available).

Browse "Exhibits," also under "Interactive Timeline," for more than 30 collections of short essays, accompanied by 2–6 primary sources per essay, covering major events and topics related to the presidents' lives and careers. Topics covered stretch from "The Stock Market Crash, October 1929" to "William J. Clinton and the Supreme Court, 1993-2001."

Try the "Gallery" to search more than 1,500 primary sources (including artifacts, maps and charts, video, photographs, sounds recordings, and documents) by keyword, library of origin, date, or source type.

The "Educators" section includes 14 ready-to-go activities, on topics ranging from Pearl Harbor to the Iran Hostage Crisis to Bill Clinton's visit to Little Rock Central High School. Students and teachers can view pre-selected primary sources online in each activity, with suggested rubrics, applicable standards, and links to related sources also included. "Resources" links out to 16 websites recommended for history and primary sources, education, and technology, while "Multimedia" rounds up more than 50 audio and video primary source clips for download.

If you can't access the interactive Flash version of the timeline, try the HTML "Text Version" that includes the same primary sources.
