In this activity, learners examine how brine shrimp populations can survive in some of the harshest environments.

Learners construct an electricity-generating wind turbine out of a plastic bottle.

If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move?

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

The purpose of this lab activity is to demonstrate (through simulation) how DNA fingerprinting (or DNA profiling) might be used to solve a crime.

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

In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

Use a Pico Cricket (micro-controller) to animate your art! You can program a Pico Cricket to make your art spin, light up, or make music.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

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

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.

In this activity, learners explore the invisible infrared radiation from an electric heater.

Learners use two mirrors to explore how images of images of images can repeat forever.

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, you take regular dominoes, and turn them into conductive switches that can turn on a LEGO RCX block or Pico Cricket (micro controller). LEGO RCX block or Pico Cricket is required.

In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.

This activity uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).
