This collection uses primary sources to compare American responses to Pearl Harbor and September 11. 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.

Innovation and technology can play a beneficial role in changing our food landscape, if we allow it to. Hydroponics and freight farms are just one of many technological advances already being utilized by communities to provide greater access to food. Spanish captions and transcript also available.

The COVID-19 pandemic affected many Minnesotans' ability to access healthy foods because of lost jobs and income, students unable to receive school meals, and myriad other reasons. Local farmers and food banks teamed up to ensure that hungry families could still eat well, while also providing income for farmers whose markets were challenged by the pandemic.

The power of the internet allows students to experience and visit places they might not be able to see in person. But, just like traveling in the real world, it's important to be safe when traveling online. On this virtual field trip, kids can practice staying safe on online adventures. This lesson aligns to national Computer Science standards from CSTA.

This website contains the on-line versions of books previously published in hard copy by the Federal Research Division of the Library of Congress under the Country Studies/Area Handbook Program sponsored by the U.S. Department of Army. The Country Studies Series presents a description and analysis of the historical setting and the social, economic, political, and national security systems and institutions of countries throughout the world and examines the interrelationships of those systems and the ways they are shaped by cultural factors.

Steganography is the science and art of hiding messages in plain sight so only the sender and intended recipient know the existence of a message. Steganography can be characterized as security through obscurity. Through this lesson, students experience a portion of the engineering design process as they research steganography and steganographic methods; identify problems, criteria and constraints; brainstorm possible solutions; and generate ideas. These are the critical first steps in the engineering design process, often overlooked by students who want to get to the "doing" phases—designing, building and testing. In computer science, a thorough design phase makes program implementation much easier and more effective. Students obtain practice with a portion of the design process that may be less exciting, but is just as important as the other steps in the process.

This podcast addresses the issue of protecting your privacy today with threats from identity theft, malware, government surveillance, and consumer profiling. Marc Hedlund speaks about how can we best protect our future selves from the quiet hard drives of today, and what might it mean to have an "open data" movement. He lists the current threats that might lead to privacy problems later and then gives some defense techniques that should help provide future protection. He also proposes a modest call to arms, stating that privacy policies modeled on the General Public License (GPL) should be developed and suggests strongly that it is best to assume that any data made available is being added to the pool.

Students apply the design process to the problem of hiding a message in a digital image using steganographic methods, a PictureEdit Java class, and API (provided as an attachment). They identify the problems and limitations associated with this task, brainstorm solutions, select a solution, and implement it. Once their messages are hidden, classmates attempt to decipher them. Based on the outcome of the testing phase, students refine and improve their solutions.
