This activity introduces the idea of "divide and conquer" using a fictitious but serious problem--a pair of dirty socks has accidentally been wrapped in one of the presents that Santa is about to deli

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

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.

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

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.

This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.

In this activity, learners conduct scientific research on multitasking. Learners determine if multitasking with media while doing homework affects their ability to successfully complete the homework.

This activity helps students learn how computers "compress" text by identifying repeating patterns of letters, words, and phrases.

In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

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

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

This activity (page 2) draws upon a familiar, computer-based concept related to visual resolution: pixilation.

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 activity requires a Pico Cricket (tiny computer).

In this activity (on page 2), one person "programs" the other like a robot to move through a space, trying to get them to avoid obstacles and reach a goal.

In this activity, learners discover that training a robot can be hard work! Learners investigate how robots complete a task by following a list of sequential instructions.

Build a musical ice theremin by programming a micro controller, like a Pico Cricket to respond to resistance generated by the ice melting, or the ice being touched.
