This three-week unit bridges the gap between construction and engineering. Students start by constructing toothpick bridges and testing them to the point of destruction. Then, they use this data to calculate each bridge’s efficiency. Moving on to the more detailed balsa bridge construction, students learn about material strength. As the culminating activity, students design and build a bridge to strict specifications with the goal of holding the maximum load possible.
Have a class of more than 24 students? No problem! Four-student add-on packages are available.
