This activity explores what it means for a computer to be intelligent and introduces the topic of what a computer program is and how everything computers do simply involves following instructions writ

This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

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

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

In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.

This activity about cryptographic techniques illustrates a situation where information is shared, and yet none of it is revealed.

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 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 math lesson, learners use simple addition facts to compute values (in dollars and cents) for their names.

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.

In this math lesson, learners apply mathematical modeling to solve a real-world storage problem, in which a manufacturing company is given two options for storing oil barrels.

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

In this design challenge, learners will use computational thinking to design their own board game.

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 use cooperation and logical thinking to find solutions to network problems on the playground.
