In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.
The Poor Cartographer: Graph Coloring
Source Institutions
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.
Programming Languages: Harold the Robot
Source Institutions
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, and how their
Divide and Conquer: Santa's Dirty Socks
Source Institutions
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
Programming Languages: Marching Orders
Source Institutions
In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.
Colour by Numbers: Image Representation
Source Institutions
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.
You Can Say That Again!: Text Compression
Source Institutions
This activity helps students learn how computers "compress" text by identifying repeating patterns of letters, words, and phrases.
Sound Representation: Modems Unplugged
Source Institutions
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.
EEEEK--A Mouse!
Source Institutions
In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.
Card Flip Magic: Error Detection & Correction
Source Institutions
This magic trick is based on how computers detect and correct data errors.
Arduino Blink Challenge
Source Institutions
In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.
Human Interface Design: The Chocolate Factory
Source Institutions
In this activity about human interface design issues, learners help the Oompa-Loompas of a great chocolate factory solve different problems.
The Muddy City: Minimal Spanning Trees
Source Institutions
In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.
Phylogenetics
Source Institutions
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.
Puzzled Partners
Source Institutions
In this web-based activity, learners try to figure out who in an online chat room has their matching puzzle piece.
Tourist Town: Dominating Sets
Source Institutions
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
The Turing Test: Conversations with Computers
Source Institutions
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.
