In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.
