This lab, presented by the National Nanotechnology Infrastructure Network, introduces students to the concepts of scale and magnification using a Scanning Electron Microscope (SEM) image of a Blue Morpho butterfly wing. If educators do not have access to an SEM,  images is included with the activity. This lesson will prompt students to think about nanoscale, biomimicry, SEM technology, and measurement. Students will examine the nanostructures of the butterfly's wings using either the images or the SEM (if available). Included in this lab are: teacher guide, student worksheet, and an image of a Blue Morpho butterfly.
