In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.
