This magic trick is based on how computers detect and correct data errors.

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution.

This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.

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

Learners can program a compass to draw a circle by itself using a Pico Cricket, some Legos, and lots of tape! Pico Cricket is required.

This activity requires a Pico Cricket (tiny computer).

In this activity, learners make their own encrypted code to pass along secret messages using a printable cipher wheel.

In this activity, learners examine nanoscale structures of common things.

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

In this activity, learners make their own binary code bracelets by translating their initials into 0s and 1s represented by beads of 2 different colors.

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 discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

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 web-based activity, learners try to figure out who in an online chat room has their matching puzzle piece.

In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

Put on a pair of gloves and be the conductor of your invisible orchestra!
