Build simple structures and test their stability using a homemade earthquake simulator. Learn about seismic activity and building design.
If a structure is designed with a wide base, then it will withstand more shaking compared to structures with narrow bases.

Build small structures from wooden blocks.
Place structures on the plastic box lid.
Attach marbles to the bottom of the lid using rubber bands.
Simulate an earthquake by gently shaking the lid.
Observe which structures remain standing.
Record the stability of each structure.
Rebuild structures with different designs.
Compare the stability of different designs.
Structures with wider bases are expected to remain more stable during shaking, demonstrating the importance of design in earthquake-prone areas.
