Nano Lessons

A repository of lessons are available for instructors that wish to incorporate cutting-edge nanoscience into their STEM curricula. Each NanoLesson contains a descriptive summary, sample lesson pages, related simulations and seminars. These Nano Lessons are targeted for the 7-12 grade classroom. All materials on the NanoEd Resource Portal are peer-managed and covered by a creative-commons attribution, non-commercial share-alike type licensing.

Please contact us if you are interested in posting your Nano Lessons.

LEGO Atomic Force Microscope and Magnetic Force Microscope

DESCRIPTION:

Scanning Probe Microscopy is an important tool for scientists and engineers. A classroom analogue constructed using Lego(R) building blocks is an effective way to represent how these tools work and to interpret the images produced by them. Background information for building a Lego(R) AFM and SPM are shown. Two laboratory activities are suggested, complete with advanced set-up information, pre-laboratory discussion, laboratory directions, and post-laboratory discussion. Instructions on making Surface Plots are included for Excel PRE 2007. More recent releases of Microsoft Excel no longer have this feature.

Approximate Length or Duration of activities:
45 minutes (It can be longer, depending on depth)

Required Skills or Prerequisites:
How a coordinate system works, measuring with a ruler or arbitrary scale, and Excel- pre 2008

Evaluation Methods:
Group questioning, laboratory report.
