A walk through for the other students would be an excellent extension to this unit. A power-point presentation created by individual students or a team displayed to create

“A Blast of the Dubious Past”

The student scenarios will be on display representing the selected periods chosen by each group, and the students will be on hand to answer question or provide additional information in regards to their project.
