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.

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 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.

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.

In this computer science activity about finite-state automaton (on page 45 of the PDF), learners use a map and choose various pathways to find Treasure Island.

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 pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

In this math activity (Page 17 of the Play Ball! PDF), learners play a game of "baseball" and analyze the results of the game.
