Get students thinking like engineers with this hands-on bridge design STEM challenge! In this second section of the Strength & Structures Engineering Unit, students design, build, and test bridges to investigate how load position affects bridge strength.

Students will explore the relationship between loading position and stability while collecting data, making predictions, testing designs, and improving their bridges through the engineering design process.
