In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.

In this activity, learners discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

In this activity, learners explore how nanosized structures can create brilliant color.

In this outdoor, night activity, learners track nocturnal animals' footprints, droppings and other signs of their presence.

In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

In this activity on page 5 of the PDF, learners compare water with artificial urine to see how urinalysis works. Learners use urinalysis test strips to test for glucose and protein in the fake urine.

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

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

In this activity, learners touch and observe skulls of sharks and rays to learn about their diversity (over 400 species of sharks alone!).

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

In this activity, learners observe and describe the physical and behavioral characteristics of insects, including crickets.

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 investigate how some butterfly wings get their color.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this activity, learners use sieves with different-sized holes to sort balls by size.
