The spaghetti bridge project requires students to build a bridge out of spaghetti and glue that spans 24 inches, is no longer than 32 inches, and can support a 3 inch by 5 inch block of wood. The bridge will be graded based on its strength to weight ratio, with higher ratios earning a better grade. Students can work individually or with one or two partners, and must turn in their completed bridges by December 20th.
