The Ad Council has been producing public service announcements attempting to affect change in society and serve the public interest for nearly 70 years. The campaigns take the form of print, radio, and television advertisements. They have run the spectrum of societal issues, from "Rosie the Riveter" and the campaign to place women in war jobs to contemporary ads related to predatory lending. The Ad Council has brought us memorable characters like Smokey Bear, McGruff the Crime Dog, and Vince and Larry (the two crash test dummies who convinced us to wear seat belts). But what do these public advertising campaigns say about America? How can we use these ad campaigns to better understand U.S. history?

Through analyzing the ads we can isolate time periods in history and understand what were believed to be the most pressing societal issues of the time. These campaigns tried to decrease behaviors that were believed to lead to social problems or promote behaviors that would lead to a better society. Thus, in seeking to understand the advertisements, we can help students uncover the contemporaneous sociology of the ad campaign.

You can begin by exploring the Ad Council's Historic Campaigns that highlight some of the more notable campaigns in the last 70 years. Each campaign is complete with background information and some have links to PSA videos associated with the campaign. An even more complete retrospective of past advertising campaigns is maintained by the Advertising Educational Foundation and can be accessed here.

I have found the site particularly useful in helping students understand more recent history. For instance, few would disagree that, socially, the 1980s were rocked by the AIDS epidemic. The site highlights PSAs to prevent the spread of AIDS, which represent a dramatic shift in societal norms with the public call for condom use. The ads on crime prevention featuring McGruff the Crime Dog also help illuminate the 1980s. These ads coincide with America's "war on drugs" and emphasis on law and order during the 1980s. 1970s culture was epitomized by environmental awareness featuring Ad Council PSAs showing Native Americans distraught to find their territory littered. These ads and more can be found in the Historic Campaigns section.

Teaching with advertisements as primary sources is beneficial in two ways. One, students are exposed to yet another example of primary sources that come with their own unique set of historical questions. Two, by learning how to unpack the intent of advertisements on people of the past, students are more apt to be able to recognize advertising manipulation in the present. The Ad Council dedicates a page of resources for educators that includes useful links and frequently asked questions. These pages also identify current advertising campaigns, which might be useful for students to identify some of the important topics of today compared to the important issues they find in earlier decades.

Before having students analyze advertisements as primary sources, it is important to model for students how advertisements should be read. Students should also be made aware of the strengths and limitations of using advertisements to understand the past. An excellent overview of these strengths and weaknesses can be found on page 11 of this guide to primary sources, from the Smithsonian's History Explorer, along with questions to guide students in analyzing advertisements.

A natural fit to teaching U.S. history through public service announcements would be to have students create their own PSAs. Students could be given a list of pertinent social issues to a particular time period or could be asked to research important topics on their own. Students could write a script and use a pocket camcorder to record their PSA. Editing could be done using iMovie, Windows MovieMaker, or any number of free online video editing tools. The purpose of the assignment is to help students understand the changing nature of social issues in the United States.

Another idea is to have students research the effectiveness of given historic campaigns. The Ad Council maintains a database of reports and figures related to the success of various PSAs. This is a condensed version highlighting the impact of the Ad Council's more famous campaigns. The purpose here is to help students see how effective advertising not only convinces people to buy products, but also can convince people to change behavior for the common good.

The Ad Council works to address the most significant social issues of the day. With that purpose, the Ad Council offers a unique look into making sense of our social past by revealing important issues of the time. Advertisements offer students an opportunity to interpret an overlooked type of primary source of the past and establish connections to the present.

Every September 17, Constitution Day calls on teachers to memorialize—and critically engage with—Constitutional history in the classroom. But what approach to the Constitution should you take? What quality teaching resources are available? How can you interest your students in a document that is more than 200 years old?

In 2008, Teachinghistory.org published a roundup of Constitution Day resources. Many of those resources remain available, but online Constitution Day content continues to grow. Check out the sites below for materials that recount the Constitutional Convention of 1787, compare the Articles of Confederation with the Constitution, explore U.S. Supreme Court cases that have interpreted the Constitution, and apply the Constitution to contemporary debates.

The Library of Congress's Constitution Day page collects the full text of the Constitution, Bill of Rights, and Amendments, as well as the Federalist Papers and the Articles of Confederation. Lesson plans for grades 6–12 accompany the documents. The page also includes short suggested reading lists for elementary, middle, and high school, and links to relevant Library of Congress American Memory collections, such as Documents from the Continental Congress and the Constitutional Convention and the papers of James Madison, George Washington, and Thomas Jefferson. Also check out the Library's collection of primary sources "Creating the United States."

You can find an elegant, simple presentation of the Constitution on the National Archives' Constitution Day page. Check out their high-resolution PDF of the original document, part of NARA's 100 Milestone Documents exhibit.

If the Constitution is proving a difficult read for your students, try the National Constitution Center's Interactive Constitution. Search the text by keyword or topic, and click on passages that are unclear to find explanatory notes from Linda R. Monk's The Words We Live By: Your Annotated Guide to the Constitution. The Constitution Center also offers its own Constitution Day page, with a short video on the creation of the Constitution, interactive activities, and quizzes.

If you're not already familiar with EDSITEment, created by the National Endowment for the Humanities, take a look through their extensive collection of lesson plans. A quick search reveals more than 90 lessons related to the Constitution.

Interested in bringing home to students the Constitution's importance today? The New York Times' Constitution Day page links current events to the Constitution in more than 40 lesson plans. The Times also invites students to submit answers to questions such as "Should School Newspapers Be Subject to Prior Review?" and "What Cause Would You Rally Others to Support?"

Can't find anything here that sparks your interest or suits your classroom? Many more organizations and websites offer Constitution Day resources, including the Bill of Rights Institute, the American Historical Association, Annenberg Media, and Consource. (Check out our Lesson Plan Reviews for a review of a lesson plan from Consource on the Preamble to the Constitution.)
