Using slinkies to show how earthquakes produce body and surface waves

The new ELI today is 'The slinky seismic waves demo; using slinkies to show how earthquakes produce P-, S- and surface waves'.

In this activity, two slinky springs are used to show how one earthquake produces P-, S- and surface waves. It can be difficult to understand how one sudden movement along a fault plane at the underground focus of an earthquake can cause three different sorts of earthquake waves with different properties.
Many more activities about earthquakes can be found on our website.

Become a fossil hunter and dig up a dinosaur

'Dig up the dinosaur; become a fossil hunter and dig up a dinosaur'.

This activity provides practice in working systematically, in contrast to simply grabbing an item as it is discovered. It could be used to amplify work on fossilisation. The use of a grid could be used to reinforce a lesson in maths or geography.
Many more activities relating to fossils and the evolution of life can be found on our website.

Modelling a divergent (constructive) plate margin

The new ELI today is 'Faults in a MarsTM Bar; pulling apart a MarsTM Bar to model a divergent plate margin'.

The activity models the processes which are taking place at oceanic ridges and continental rift valleys, and enables pupils to see that tensional forces can produce “rift valleys”. It is appropriate in both geography and science lessons AND it can be eaten afterwards!
