How Small is That?

This lab is designed to help students understand the size of nanoparticles compared to the size of other known quantities, such as a human being or a skin cell. Students will explore relative size, and the idea that cells are quite big when compared to nanoparticles. After the size of nanoparticles is understood, the students will be challenged to come up with a way to "save" nanoparticles from being polluted by larger objects. Their design will be presented in the form of a comic strip.
