This activity about cryptographic techniques illustrates a situation where information is shared, and yet none of it is revealed.

In this activity, learners electrically plate zinc onto brass objects.

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.

This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

In this activity, learners will use household items to design and build an elevator that will carry 2 passengers to a height of 16 inches...or higher!

Learners will follow a specific process to make their own paper using scrap paper, newspaper, or junk mail.

This is a web page that helps informal educators brainstorm on how to use a Pico Cricket (tiny computer) in an informal activity.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

Build a musical ice theremin by programming a micro controller, like a Pico Cricket to respond to resistance generated by the ice melting, or the ice being touched.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

In this activity, learners explore the principles of magnetism by observing how various materials interact with magnets and superconductors.

Build a phonograph record player using a cactus needle, a record, LEGOs gear box, and a piece of paper! This activity uses a Pico Cricket to turn the motor.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

In this activity learners will build roller coasters and test them using small balls or marbles.

What's a more compelling problem to solve than being stranded on a deserted island?

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
