PBL Bridge Building PBL Bridge Building ProjectProject
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
Video Playlist – 10 segments
“How stuff works” – Bridges

(Ten video segments each 2-4 minutes long on various parts of bridges, how they
work, collapses, etc.)
