Scale Models: Size, Scale and Measurement

This lesson, presented by the National Nanotechnology Coordinated Infrastructure, 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. A Teacher Preparation Guide is included.
