ELI activities in the Geopark of Central Catalonia

In November 2017, a presentation of Earthlearningidea activities was made in the Geopark of Central Catalonia. The activities were included as part of the training programme for tourist promoters working within the Geopark. 
The photos have been included in the Photo gallery on the ELI website.
There are many activities on the website that can be used for presentations like this one.

Interpret Earth temperatures from simulated deep-sea and ice cores

The new Earthlearningidea today is 'Interpret Earth temperatures from simulated deep-sea and ice cores' This activity uses sweets to simulate oxygen isotope ratios in cores.

This is an activity to plot Earth’s temperature indications from mock ice and deep-sea sediment cores. The activity consolidates understanding of how the 18 O: 16 O ratios in ice cores and deep-sea cores respectively can be interpreted in terms of warmer (interglacial) or cooler (glacial) Earth temperatures.
More activities relating to climate change can be found on our website.

Continental drift

'Did the continents move for you?' This Earthlearningidea plots the movement of continents using apparent polar wandering curves.


This exercise can be used in any science or geography lesson about plate tectonic theory and the movement of the continents.
Many more activities related to plate tectonics and continental drift can be found on our website.

Temperatures on Earth in the past - using oxygen isotopes

Today's new ELI+ activity is 'The oxygen isotope sweet simulation; demonstrating how the oxygen isotope proxy records past Earth temperatures'.

Using coloured sweets, the activity simulates how the relative proportions of 16O and 18O can indicate past Earth temperatures.
Many activities for students aged 16 plus can be found on our website.

Limestone karstic scenery - in 60 seconds

Have you tried modelling the chemical weathering of limestone? Try the Earthlearningidea 'Karstic scenery - in 60 seconds' 


This activity can be used in any science or geography lesson and leads into a detailed discussion of karstic scenery and how it develops. There are many other activity ideas related to weathering and to limestone on the website.

Rock cycle at your fingertips

Today's new ELI is 'The rock cycle at your fingertips; modelling the rock cycle with your fingers'

The rock cycle is an abstract concept which pupils can find difficult to understand. For example, when asked how a rock formed, one student responded, “It went through the rock cycle” much as laundry goes through a wash cycle – something that is done to a rock to change it.’ This activity helps to explain the process.
Other teaching ideas about the rock cycle and many suggestions for hands-on activities, can be found on our website.

Demonstration of how limestone is weathered

The ELI 'Weathering limestone – with my own breath!' is a classroom demonstration of how limestone is weathered. It involves blowing into neutral water to produce a weak acid. Powdered limestone is added to neutralise the acid, as a quick-acting laboratory example of how limestone is weathered in the
natural world.


This activity may be used in Geography or Science lessons.
Many more activities related to all types of weathering may be found on our website.
