Timelines.tv is a nice little resource for history teachers to bookmark and share with their students. On Timelines.tv you can find six timelines of important eras in U.S. and European history. Each timeline includes short (3-10 minute) videos about people and events in the era. The timelines also include pictures and short text descriptions. The six timelines currently available are A History of Britain, The American West, Medicine Through Time, American Voices, The Edwardians, and Nazi Germany. More timelines appear to planned for publication in the future.
Applications for Education
The timelines that I looked at weren't the most comprehensive timelines I've found, but the videos that I watched were good. Timelines.tv could be a nice resource to share with students as a tool to review an era after you have taught some lessons on it.
