Knex Bridge building Teachers Guide (pdf file). Introduction to Structures. Introduces the pupils to the Knex bridge building kits.

This K’NEX construction set is designed to introduce students to the history, function, structural design, geometry and strength of bridges. An investigation of bridges helps students develop a good general understanding of the forces involved in structures. They will also gain knowledge of the physical properties of materials and their application in the design and construction of bridges. They will discover that bridge construction, although based on simple scientific concepts, often requires complex engineering solutions. As students use this K’NEX set, they will have the opportunity to acquire skills using a hands-on, inquiry-based approach to information and concepts. Working cooperatively, they are encouraged to interact with each other as they build, investigate, problem solve, discuss, and evaluate scientific and design principles in action.

**Week Two/Three**

Groupwork to build first two Knex bridges and perhaps a powerpoint presentation on real life images of the type of bridge built. Ie Beam bridge, Truss Bridge.

Class split into two groups, each group to build one of the larger bridges from the Knex real bridges sets.
