Overarching Unit-level Question

In this unit on the ancient city of Pompeii and the eruption of Mount Vesuvius, students are first introduced to the overarching unit-level question, “Was it irresponsible of the people of Pompeii to live next to Mt. Vesuvius or were they victims of an unexpected disaster?” Notice that the first lesson, students are introduced to the question as they build background knowledge about volcanoes and the ancient Roman Empire. In subsequent lessons, they read about a group of friends who are discussing Pompeii and identify their perspectives on the topic. Later, they read more deeply about the civilization of Pompeii and the volcanic eruption before moving on to discussing, debating, and writing about the guiding question.
