Scale Models

This lesson, presented by the National Nanotechnology Infrastructure Network, covers the general concept of scale by demonstrating factors of ten. The activity "facilitates the introduction and reinforcement of the metric scale and paves the way to the discussion of lengths that are smaller than what can be seen with the naked eye." The lesson also introduces the idea of using different tools to address different length scales which is fundamental to learning about nanotechnology. Future activities could introduce atoms and cell structure as well as recent advancements in technology. A Teacher Preparation Guide is included.
