Expedition’s Benefit and Cost

This debate and writing worksheet invites students to evaluate whether the Lewis and Clark Expedition produced more positive or negative outcomes. Learners complete a T-chart listing benefits to the U.S. and costs to Native peoples and the environment, then write a short argumentative paragraph with evidence. The task promotes balanced analysis and evidence-based writing, encouraging students to weigh differing historical perspectives. It strengthens persuasive composition and understanding of cause and consequence in history.
