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

This activity introduces the idea that computer scientists measure information by how "surprising" a message is.

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

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

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.

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.

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

In this math lesson, learners make estimates to analyze the number of apples per acre, and visualize the magnitude of one million.

Computers are often used to put lists into some sort of order—for example, names into alphabetical order, appointments or e-mail by date, or items in numerical order.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this math lesson, learners determine and compare the rate of descent of various learner-constructed parachutes. Learners construct parachutes that will have maximum hang times.
