In this activity, learners design miniature cars. Learners can create a telephone car, soccer car, merry-go-round car, or any other theme car they can imagine.

In this activity, learners construct drawing machines using a cup, some markers, and a cricket to control the movement. A programmed LEGO RCX or Cricket is required for this high-tech version.

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 activity, learners create painting machines that can paint moving forwards and backwards.

In this activity, learners construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves.

In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

Learn about friction and kinetic energy with this cool spinning toy.

This is a simple activity for learners to create a traditional musical instrument. Pan Pipes have developed all over the world in different cultures, from South America to Greece and China.

From this How To slide show, you create an Audio Tape Bow that can play distorted audio sounds by running it across a tape head.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!

In this activity, learners explore electricity and conductivity to find that many things conduct electricity including copper, pencil lead, fruit, play-doh, and even people!
