This activity about cryptographic techniques illustrates a situation where information is shared, and yet none of it is revealed. A group of learners will calculate their average age without anyone...

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow,...

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 demonstrates three search...

In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada. Learners are challenged with figuring out how to connect the...

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 introduces the idea that computer scientists measure information by how "surprising" a message is. Learners play the game "20 Questions" and use the number of...

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...

In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners. This activity works with two learners but is most...
