Interactive timelines can be a great way to present a lot of individual facts and data in a visual, unified way that can help students make connections to larger themes and movements. Timelines can help in the understanding of chronology, cause and effect, and how events in different areas overlap and affect each other. Timeline JS, from Northwestern University, is a free online tool that helps you (and/or your students) create interactive timelines using a Google spreadsheet.
