Last week we welcomed Charlie and Justin from the Earth Sciences department at Oxford University. They taught pupils how earthquakes are caused at plate boundaries, extending their knowledge into P and S waves. Pupils were delighted to be able to generate their own seismic waves, created by jumping in time with each other, and measured using a homemade lego Seismometer. Pupils were then challenged to construct the tallest and most stable marshmallow and spaghetti tower, tested for stability using the shaker tables.
