For a major Social Studies PBL, BHS STEM Academy freshman constructed their own detailed, imaginary continent in World Geography. Then, as sophomores, each student creatively developed a series of civilizations on their created continent. These civilizations paralleled our real world’s stages of history, and so demonstrated understanding of information learned over the course of the school year. As the PBL enters the second semester, students become a members of a group that digitally creates their own planet using their existing continents from World Geography. During the final six weeks, a Web Page created by the group will showcase the history of each digital "world" beginning with the River Valley Civilizations through the Middle Ages. This web page will form the final product for the year and students will showcase their planet's “history” to invited experts.
