Earthquake simulator

We wanted to establish which shape base was the strongest for skyscrapers. We decided to build models of skyscrapers using LEGO and K’nex and then use LEGO We Do to create an earthquake simulator. We placed the models on the simulator to test how robust they were. Unfortunately the models were either too heavy for the simulator to move or too tall to stand upright on the simulator! We tried it on the table and carpet in the hope that the amount of friction would help, it didn’t. One of our class members thought to attach a LEGO plate as a base for the models to stand on, this didn’t work either!
