In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

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/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.

Learners can program a compass to draw a circle by itself using a Pico Cricket, some Legos, and lots of tape! Pico Cricket is required.

This activity (on page 2 of the PDF under GEMS Activity) is a full inquiry investigation into technology design and testing.

In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.

In this outdoor activity, learners design devices that will catch prey or gather plants.

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

In this math lesson, learners make estimates to analyze the number of apples per acre, and visualize the magnitude of one million.

In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard.

In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

This activity (on page 2 of the PDF under SciGirls Activity: Hockey) is a full inquiry investigation into how a hockey stick’s flex affects shooting power and accuracy.

In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

In this activity, learners create and experiment with wind tubes. These tubes are a playful and inventive way to explore the effect that moving air has on objects.

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