Lesson Focus

Lesson focuses on how materials behave differently as their surface area increases. Students learn about nanotechnology and how engineers can harness the differences in how materials behave when small to solutions for challenges in many industries. Students 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 student teams, reflect on the experience, and share observations with the class.

  • teamwork

Lesson Activities

Students explore how the surface area of some materials impacts how they behave, and how engineers use this change in behavior to develop solutions to societal challenges in many industries. Students develop hypotheses and then test how whole and crushed antacid tablets will behave in water. Teams evaluate the results against their hypotheses, compare their team’s results with those of other student teams, reflect on the experience, and share observations with the class
