6th Grade Scientists Build Earthquake-Resistant Structures

With the completion of their recent plate tectonics and earthquake unit, 6th grade science students built earthquake-resistant structures this week. They also built their own shake tables to test their prototypes. The students applied what they had learned about three types of substructures that engineers commonly use: shear walls, cross beams, and gussets. The challenge was on as the student groups all tried to build the highest building that could successfully withstand 10 seconds on the shake table. They also had the opportunity to purchase more materials for their structure by trying their luck with the “Wheel of Chance.” Each outcome on the wheel was different, and students were required to perform a cost benefit analysis, simulating decisions that engineers must make when trying to build a safe, affordable structure.
