Sedimentary structures - graded bedding

'Sedimentary structures - graded bedding: make your own graded bed – one depositional event, but with coarse to fine sediment'

This ELI is a teacher demonstration (or a small group activity) showing the origins of graded bedding. It can be used in any lesson dealing with the origin of sediments and the interpretation of past environments.

When are soft rocks tough, and hard rocks weak?

New ELI today - 'When are soft rocks tough, and hard rocks weak? A discussion about the toughness/resistance of rocks in different places'

The simple idea, which generally holds, of tough rocks forming hills and headlands and weaker rocks, valleys and bays, does not always apply. This activity looks for evidence of when and why it is not always true.
Many activities related to rock resistance can be found on our website.

Bringing a fossil 'back to life'

A popular ELI is 'Running the fossilisation film backwards; bringing a fossil ‘back to life’'

This is a thought experiment, including possible re-enactment, to recreate the likely ‘final moments’ of an animal which later became a fossil. The activity provides examples of how to ‘run the fossilisation film’ backwards to help pupils to visualise what a fossil may have looked and acted like during life and in the few moments before death.

Jelly Babies (TM) and Geological maps

The new ELI today is an ELI+ written for older pupils who are learning about 3D geological maps. 'The sliced Jelly Babies^TM approach to understanding 3D geological maps; use Jelly Babies^TM cut at the dip angle to highlight structures on geological maps'

This activity shows the dip of fold limbs on a geological map using sliced jelly sweets to show bedding plane dips.

Choose the power source

'Which power source? – solving the crisis in Kiama: searching for all the power sources that could be developed in a mythical country'

 

Pupils study a map to find clues to the different energy sources that could be exploited in a mythical country. Possible power sources with some of their advantages and disadvantages are shown in a table provided in the activity.
