Surface Area to Volume Ratio
This resource from the Midwest Regional Center for Nanotechnology Education (NANO-LINK) is one of a series that introduces students to the the forces and interactions central to understanding nanotechnology. In this module, students will learn about the relationship between surface area and volume, specifically how "for a given volume of material the total surface area increases non-linearly as the volume is divided into smaller and smaller pieces," and how this relationship is being applied in nanotechnology. The page includes an instructor guide and a PowerPoint presentation detailing the materials needed and steps required to complete this lesson. The lesson requires background knowledge...
