This task, students are asked to consider why lithium, magnesium, and sodium react with water in such different ways, focusing on patterns of element properties reflected by the periodic table and how they contribute to reactivity in chemical reactions. This task is intended to be used as an assessment of student understanding of an unpacked "part" (the learning performance described) of a performance expectation (PE). This task was developed by the team at CREATE for STEM at Michigan State University.
