PBL Bridge Building Project So Many Types of Bridges How Do Bridges Work ? Designing Your Own Bridge Constructing Your Own Bridge
What are you going to be doing? *Math is the leading subject of this PBL project *In Math classes, you will spend at least nine class periods designing and building your own bridges in groups *In Science, Social Studies, and Language Arts – you will be doing background research, learning about factors that influence bridge strength and stability, and the history of bridges in our country and world.
What are you going to be doing? *In May, you and your groups will be presenting your bridges to an audience of other classmates, teachers, community members, and engineers. *This will be a project that you will be working on at school, in your classes, at various times from today through the end of April.
Day 1 – Introduction • Research the history - Close Read of “History of Bridge Development” • Analyze different and basic bridge types • Explore how bridges work • Watch videos on bridge design and failures • Play online bridge building games
