Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

In this activity, kids make and play with Ooze before testing the material in an egg drop!

In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

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

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.

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

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this activity, learners investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.

In this activity, learners will be able to measure themselves in nanometers. A nanometer is a billionth of a meter, a unit of measurement used in nanotechnology.

In this activity, learners use their sense of smell to explore the world on the nanoscale.

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.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

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, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.
