This lesson, presented by the National Nanotechnology Infrastructure Network, is designed to introduce middle and older elementary students to nanoscale objects by comparing them in size to the visible world. Students will receive an introduction to exponents, decimals, and the metric system through these size comparisons. The included 'Teacher's Preparatory Guide' details needed materials and instructions for the lesson, as well as a list of additional useful resources to assist students in comprehension. Two additional files include those materials to print for the activity: scale indicators and a PowerPoint file with images.
