Simple Pop-Up Mechanisms
Source Institutions
In this activity, learners construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.

Canine House of Cards
Source Institutions
This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog biscuit.

Box Ecology
Source Institutions
This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.

Building a 3-D Space Maze: Escher Staircase
Source Institutions
In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

Building an Army
Source Institutions
In this activity, learners explore the potential of interchangeable standard parts to create a large number of unique creations in different combinations.

Tessellations
Source Institutions
In this activity, learners will engineer a new shape and use it to create a new pattern with no wasted space.

Getting There!: Navigation and Trajectory
Source Institutions
In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

Strong Shapes
Source Institutions
Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

Make Ziff's Carpenter's Square
Source Institutions
In this Cyberchase activity, learners make carpenter's squares and use them to measure square corners. Learners cut out the carpenter's square template and attach it to tagboard.

Straws and Airplanes
Source Institutions
Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

Perspectives: Powers of 10
Source Institutions
In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.

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.
Build a Bridge
Source Institutions
In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

Postcards from Space
Source Institutions
Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

Manufacturing Technologies: Making a Picture Frame
Source Institutions
Learners examine the manufacturing process while they make picture frames from cereal boxes.

Binary Code Bracelets
Source Institutions
In this activity, learners make their own binary code bracelets by translating their initials into 0s and 1s represented by beads of 2 different colors.

Paint by the Numbers
Source Institutions
In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

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.

Secret Writing Devices
Source Institutions
In this activity about encryption, learners cut out a secret decoder badge from a handout and use it to encode messages to each other.
Building Houses: Build a Cardboard Tube House
Source Institutions
Build a house you can fit inside, using cardboard tubes.
