Bridge Design and Evaluation Concepts

This instructional video, created by Sha Kupa, guides students through building and testing popsicle stick bridges. It covers the importance of bridges, basic design principles, and different types of bridges, such as beam, arch, truss, suspension, and cable-stayed bridges. The video includes a challenge where students design and construct a bridge, considering budget and efficiency. The video concludes with evaluation criteria and key take-home points about bridge design and construction.
