After learning about the strength in triangles in building structures, our second graders were challenged to design and build the strongest bridge possible using Popsicle sticks and wood glue. Students came to the Design Lab and worked on this design challenge for five sessions. During the sixth session we used a bridge crusher made by Parent Parnell Pollioni. Mr. Pollioni was instrumental in planning, teaching, and supplying material for this challenge. Ana and Keira from Mrs. Faleschini's class came in first place by building a bridge that held 198 pounds with a bridge efficiency of more than 643. In future challenges, all the second graders will know the importance triangles play in structural strength.
