This is written as a static display, but can easily be adapted to a hands-on experiment for learners to conduct.

This activity lets you program your 'robot' (a willing friend) to pick up and dispose of some 'toxic waste' using as few commands as possible.

This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

This activity demonstrates the specificity of viral vectors for target cells in gene therapy delivery methods using two approaches: 1) STYROFOAM® models demonstrate viral ligand binding to receptor pr

In this activity, learners design a flag for a chosen or assigned planet. The instructions include information about flags on Earth, and a list of flag references.

This activity was designed for blind learners, but all types of learners can use it to build and examine a basic electrical circuit.

Learners are given mysterious white powders and have to determine their identity with chemical tests.

In this activity, a spinning bicycle wheel resists efforts to tilt it and point the axle in a new direction.

In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

In this adapted version of poker, learners practice writing chemical formulas by playing this chemistry card game.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

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

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

This activity was designed for blind learners, but all types of learners can use it to investigate how different materials vary in their conduction of heat.

If you have access to a copper metal tube, this activity does a great job demonstrating what happens to matter when it's heated or cooled. This activity requires some lab equipment.

In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

In this activity, learners use pedigree and jigsaw puzzles to explore how scientists use genetic information from a family to identify a gene associated with a genetic disorder.

In this activity (described on pages 39-42 of PDF), learners make a paper wheel (on pages 57-60 of PDF) that shows them the relative loudness of different sounds.

In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.
