To review and pre-teach content material, this fun and engaging 100th Day of School activity is a great way to get students interested in the major historical events of the last 100 years. To begin the activity, the teacher will either write on the whiteboard or announce that today the class is going to assume the role of Historical Investigators, revealing the most exciting events in history over the last 100 years. The teacher will then group the students into groups of 2-4 based on the class size. The teacher will pass out the investigation sheet, and direct students to open the Google Slide presentation. The teacher will model how to select and research a given historical event using credible sources. 

Applying computer science principals, students will explore inventions & innovations from the Age of Information, then through pattern recognition, compare and contrast the Age of Information with the Age of Industrialization. Students will present their research to peers. 

Tuning into the radio is now an integrated part of our everyday lives. We tune in while we drive, while we work, while we cook in our kitchens. Just 100 years ago, it was a novelty to turn on a radio. The radio emerged at the turn of the twentieth century, the result of decades of scientific experimentation with the theory that information could be transmitted over long distances. Radio as a medium reached its peak—the so-called Radio Golden Age—during the Great Depression and World War II. This was a time when the world was rapidly changing, and for the first time Americans experienced those history-making events as they happened. The emergence and popularity of radio shifted not just the way Americans across the country experienced news and entertainment, but also the way they communicated. This exhibition explores the development, rise, and adaptation of the radio, and its impact on American culture.

This activity activates prior knowledge while developing insight into historical perspectives. Use this activity to help students broaden their horizons and explore diverse ideas.

This collection uses primary sources to explore the invention of the telephone. 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.

Students will explore primary and secondary sources to investigate the origin, purposes, and vitality of Historically Black Colleges and Universities.
