In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

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).

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.
