Earthquake prediction

Click here to view the latest activity 'Earthquake prediction - when will the earthquake strike?' In this activity we model how forces acting in the Earth can build up stresses, which are suddenly released when rocks fail (fracture). This activity could form part of a lesson on earthquakes and their effects, leading to an understanding of the difficulties faced by civil authorities in clearing an earthquake-prone district in time to prevent casualties. It is also a useful application of the theory of forces.
Remember to let us know how you get on when you try this Earthlearningidea.

I have tried this activity with a top set year 9 and I had a good response. They pulled on the bricks and saw that an increasing force is needed to make the bricks move and that the spring beneath the table forms waves. They also noticed that less force is needed to make the bricks move if they are wet.
