Curated OER
Triangle Exercises
In this math worksheet, students determine the name for each triangle according to its classification. Then they create a truss construction model.
Curated OER
Toothpick Bridge Design
Eighth graders are introduced to what makes a strong, sound structure. They explore about the truss structure, the importance of the strength of the triangle and the distribution of forces along the truss. Students work in teams to...
Curated OER
Lab for Truss Design and Testing
Students design and build their own truss. In this physics lesson, students calculate the forces and maximum load. They complete a full scale diagram of their design.
Curated OER
The Difference is the Truss
Students use a computer to simulate building and testing bridges with various types of trusses.

Science Buddies: The Effect of Bridge Design on Weight Bearing Capacity
This Science Buddies project asks that you identify different kinds of bridges, discover why they are built as they are, and then build three different bridges of your own out of balsa wood. See which one you think can bear the heaviest...

Teach Engineering: Straw Bridges
Working as engineering teams, students design and create model beam bridges using plastic drinking straws and tape as their construction materials. Their goal is to build the strongest bridge with a truss pattern of their own design,...

Teach Engineering: Right on Target: Catapult Game
Students experience the engineering design process as they design and build accurate and precise catapults using common materials. They use their catapults to participate in a game in which they launch Ping-Pong balls to attempt to hit...

Teach Engineering: Truss Destruction
Students work within constraints to construct model trusses and then test them to failure as a way to evaluate the relative strength of different truss configurations and construction styles. Each student group uses Popsicle sticks and...

Teach Engineering: Triangles & Trusses
Learners learn about the fundamental strength of different shapes, illustrating why structural engineers continue to use the triangle as the structural shape of choice. Examples from everyday life are introduced to show how this shape is...
