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

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

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

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 activity, learners use a fictitious map of "Tourist Town" and counters to problem solve how to place ice-cream vans on street intersections so that every other intersection is connected to one

In this activity, one person acts as a human robot while another acts as their developer by programming their actions.

In this activity, learners will explore how product barcodes are scanned accurately and be able to "guess" the last number in a 13 digit barcode correctly every time.

In this activity, learners will explore how computers represent pictures using pixels.

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

In this activity, learners play a game similar to Hangman by guessing a secret phrase to understand how computer scientists measure the amount of "information" in a document.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.
