This lesson focuses on how materials behave differently as their surface area increases. Learners investigate nanotechnology and how engineers can harness the differences in how materials behave when small to solutions for challenges in many industries. Learners work in teams to explore examples of how surface area impacts functionality. They hypothesize how surface area will impact the performance of antacid tablets, conduct an experiment using whole and crushed tablets to see how they behave when introduced to water, observe what they see, extrapolate to other examples, compare their hypotheses and the results with those of other teams, reflect on the experience, and share observations with the group. http://datadiscoverystudio.org/geoportal/rest/metadata/item/e1c6b20481c44e24b42787a56565f6b1/html
