This week we learned about the importance of triangles in construction engineering which is Amir's interest. Using triangle shaped building supports adds exponetial strength to any structure. The children saw this hands-on using toothpicks and gumballs. We built the bridge trusses pictured together. Amir was really excited about this, and so was Yasina. She built a nice pyramid that I'll upload next time. (*updated*)
Amir says he looks like a fire fighter in the outfit he has on. I think he looks like a general contractor.
