Journey to the centre of the Earth – on a toilet roll

'Journey to the centre of the Earth – on a toilet roll: just how thin is the crust we live on?'


We seldom stop to consider the true scale of many features of the Earth. This activity aims to enable pupils to visualise the thickness of the crust in relation to the rest of the Earth. It also helps them to appreciate the difference in depth between the oceanic crust and the continental crust. It introduces the terms ‘lithosphere’ and‘asthenosphere’ to help in understanding plate tectonic theory.

Does sea level change when floating sea ice melts?

The new ELI today is 'Melting ice and sea level change 1 – sea ice: does sea level change when floating sea ice melts?'


This activity investigates the impact on water levels of allowing floating ice to melt. There is much misunderstanding of the impact on world sea level of melting sea ice, which this simple activity should dispel.
Many more activities about climate change and the changing state of ice can be found on our website.
    

Pressures underground

From our ELI+ series - 'Under pressure: calculating the intense pressures underground'


This activity uses lab measurements of the force applied by different depths of sand and water to calculate their downward pressure and then uses these figures to extrapolate to likely pressures at crustal depths.
Many more ELI+ activities can be found on our website.
    

Recreating the rocks – step by step

The new ELI today is 'Recreating the rocks – step by step: simulating a dipping sedimentary rock sequence though a sequence of Earthlearningideas'.


This teaching strategy can be carried out in the field in front of a dipping sedimentary sequence or in the classroom with an image of such a sequence on a screen. It helps pupils to understand step by step the creation of the sedimentary rocks they can see.

Developing a strategy for evaluating the environment

'Environmental evaluation; developing a strategy for evaluating the environment'


In this activity, pupils are given a scale to use in environmental evaluation, and then asked to apply this scale to different environmental circumstances, that can range from a local small environment to a panoramic view. The objective of the activity is to develop an evaluative approach to environments of all types, which pupils can apply wherever they are in the future.
