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.

In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

In this game, learners experience how computers divide a big problem into many smaller ones and how they use binary "yes"/"no" questions.

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 lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

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.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their

In this activity, learners recreate a method of detecting and correcting errors in computers called 'parity'.

In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through

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 about human interface design issues, learners help the Oompa-Loompas of a great chocolate factory solve different problems.

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.

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

In this activity, learners cut out 5 paper cards and label them with 1, 2, 4, 8, or 16 dot(s) to explore binary digits.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.
