This document provides instructions for Milestone Four of a critical analysis portfolio assignment. Students are asked to analyze a previously chosen issue or event related to diversity through the lenses of the natural/applied sciences and social sciences. For each lens, students should explore how the issue can be viewed through that disciplinary perspective and how it impacts social institutions. Students must submit two papers analyzing the issue through each lens separately, citing at least two sources to support each analysis. The papers should be 2-4 pages total following standard formatting guidelines. The submission will be evaluated based on the quality of the lens analyses and clarity of writing.
