This document outlines a lesson plan for a 7th grade technology class on bridge building. Students will use software to design bridges virtually and then build physical models. They will: 1) Learn bridge design using the West Point Bridge Builder software and tutorials over 3 days. 2) Record explanations of their virtual designs and testing using Jing screen recording software. 3) Spend 2 weeks constructing balsa wood bridges applying their design knowledge. Their grade will be based half on the quality of the Jing recording and virtual design, and half on the efficiency of their physical bridge model.
