Exploring at the Nanoscale
This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale. Learners participate in hands-on activities to understand exactly how small the nanoscale is, explore how surface area changes at the nano scale, and work in teams to develop futuristic applications of nanotechnology. Specifically, teams of learners examine and measure blocks of tofu or gelatin to determine the surface area. Then they slice the blocks into smaller and smaller pieces, exposing more surfaces, and impacting the surface area. Learners also explore the size of small by comparing various items to understand the size of nano.
