When we see a rock as a bundle of evidence of how the Earth used to be, we can begin to look for the clues that tell us about its past history, and the past history of the planet. Rocks are natural time capsules. By using the ‘time capsule’ approach you can bring a rock to life in ways that will amaze pupils and adults alike.
The ELI category 'Visualising deep time' has related activities and activities about rocks generally can be found here.
The new ELI today is part 2 of 'Walther’s law of sedimentation – teaching it the Lego TM way: How does a relative fall in sea level affect a vertical sequence of sediments?'

The new ELI today is 'The soil water shake test; investigate the components of soil'.
There is a teaching video to accompany this activity.
This activity can be carried out as a teacher demonstration or as a group activity. It shows how the components of soil may be separated and studied. Various soil types can be compared.
In the Soil section of Earth Materials, you can find many more activities about soils.
