For the past twenty years, a major project for the author's eighth-grade art classes has been a group diorama with plaster figures. The group has to include two to four people participating in a sport or an occupation while showing some kind of action and interaction. Not too long ago, a couple of girls asked to depict the signing of the Declaration of Independence and give it to their social studies teacher, Mrs. Lee. The author thought, why not have the dioramas depict important events in American history and make a three-dimensional timeline? So, in collaboration with Mrs. Lee, the three-dimensional timeline was born. In this article, the author discusses how the author brought American history to life through the three-dimensional timeline of American history.
