This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this activity (on pages 19-21 of the PDF) learners observe mold growing on potatoes. Preparation for this activity has to start a week before, to allow time for the mold to grow on the potatoes.

This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete
