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

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

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 create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

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 optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.

Through a series of simple body movements, learners gain insight into the relationship between time and astronomical motions of Earth (rotation about its axis, and orbit around the Sun), and also abou

In this series of activities (page 5), students are introduced to the design process.

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.

Audio Boggle is an activity that lets you listen to a track (that you make yourself) and see what you can hear!

Margaret Pezalla-Granlund, a Minnesota artist, came up with this really fun and surprising activity using graphite from a pencil, connected with a Pico Cricket to tell a story: "The first time I saw s

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).

In order to examine the random nature of mutations and natural selection, learners "breed" clutches of Egyptian Origami Birds (Avis papyrus) using random number generators (dice and coins) to mutate s

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 activity, learners explore the concept of insulation by trying to keep Olaf the Snowman from melting. This activity encourages critical thinking and problem solving.

Make two firefly lanterns, then program them to blink to one another and change colors.

In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

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

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.
