**Designing Strong Bridges with Popsicle Sticks ** with marking scheme Introduce the problem statement. In this project, your challenge is to design and build a bridge using only popsicle sticks and glue. Your goal is to create a bridge that showcases strong structural concepts and makes the most of how much weight it can carry compared to its own weight. The focus is on making a bridge that works really well and can support a lot of weight while using only a few materials. Let’s explore the world of building strong bridges and see how well you can balance making it strong and creative in your design.
