Straw Bridges
Pairs work as engineering teams to design and build model bridges from drinking straws and tape. In this third segment in a series of 10, teams compete in an attempt to build the strongest bridge. To help with the design, the groups...

Bridging the Gaps
The London Bridge should not have fallen down. And here's why. After a brief history of bridges and the three main types, class members are introduce to the concepts of tension and compression, the two main forces acting upon bridges.

Bridge Types: Tensile and Compressive Forces
Bridges rely on tension and compression to keep them standing. Pairs test this principle by constructing simple bridges and applying a force to the center. Teams use the provided activity to record their observations of the reaction of...

Lossy Compression and File Formats
I'm compressed. Groups do a rapid research of different file types to determine what kind of compression the formats use and how it works. They share their information with the rest of the class until everyone has all the information for...

Text Compression
The second lesson in a unit of 15 introduces pupils to text compression. The class begins with discussing how they already use text compression when sending text messages. Pairs learn more about the subject as they work to compress a...

Colour by Numbers–Image Representation
How do computers store and send images? Here's an activity that explains one way a computer can compress image information. Pupils decode run-length coding to produce a black and white image. Pairs then work together to code and decode...

Twenty Guesses—Information Theory
How do we determine how much information to include and what can be left out? By playing a game of 20 questions, the class generates the best strategies for finding a number. They then move on to guessing the next letter in a short...

Sounds from Vibrating Air
Take note, or notes, as the case may be. A scientific music lesson is the third in a set of eight covering waves and instruments. Scholars use straws, test tubes, and water to create various wind instruments. Then, they read and answer...

Strong as the Weakest Link
Learners recognize that compression and tension forces are important considerations in building structures. They construct their own building structure using marshmellows and spaghetti to see which structure can hold the most weight.
