How partial melting helps to explain igneous rocks

Comparison of a model with reality to develop understanding of the partial melting process; 'Partial melting model and real rock' - an ELI+ activity.

 

This ELI is a consolidation exercise on partial melting, to ensure that students understand how a model mirrors processes in real rocks. The partial melting process can be directly linked to the key rock-forming minerals by reference to Bowen’s Reaction Series, which is explained in the activity.

Using chocolate to model plate margins

New ELI today is 'MarsTM margins - diverged, converged and transformed; modelling plate margins with a MarsTM bar - apart, together and side by side'

A demonstration of the three types of plate margins, their stress fields and characteristics using a MarsTM Bar. This activity is a bit messy but very enjoyable!

Other Earthlearningideas to do with plate margins can be found on our website.

Wriggling your toes on ancient bedding planes

The new ELI today is 'What would it feel like to wriggle your toes on an ancient bedding plane as the sediment was being deposited? Clues from the present day about the origin of sedimentary rocks'.

This activity enhances understanding of the energy levels involved in the deposition of sediment, from a series of photographs, which in many cases will prompt pupils to reflect on their own experience. It can be used to reinforce learning of sedimentary environments and their products and can be accessed from about 7 years of age upwards.

Many more activities about sediments and sedimentary environments can be found on our website.

Which power source might be built in the view you can see from your window?

'Power through the window; which power source might be built in the view you can see from your window?'


Pupils are asked to consider which of the commonly available power sources (coal, oil, natural gas, nuclear, hydroelectric or wind) COULD be built near their school/home, before being asked to think about whether the less common power sources would be viable there (solar, geothermal, tidal, wave). They are then asked to give their views on whether one of these SHOULD be built there.

Many other activities about power sources can be found on the website by using the search engine or the alphabetical index.

What catastrophic natural processes have affected your region?

New ELI today:  'What catastrophic natural processes affected your region in the geological past? Use the evidence in your local region to interpret dramatic geological events'

In this activity several photographs are used to stimulate discussion about possible rapid geological processes in the past which might have had “catastrophic” outcomes if there had been humans on the Earth at those times. How could these disastrous processes have affected your area?

Many detailed activities associated with natural hazards can be found in the Natural Hazards category on our website.

Using sponge rolls to investigate folds and faults

'Swiss roll surgery; investigating geological structures and their outcrops using sponge rolls'

 

This activity can be used in any science or geography lesson when folded and faulted rocks are discussed. By adapting the terminology, it can be used with any age group when explanations of folded and faulted rocks are required.

Many more Earthlearningideas about folding and faulting can be found on our  website.

Confused about solar and lunar eclipses? Try this!

The new ELI today is 'What would an eclipse look like from the moon? From the moon, what would the Earth look like during a) a solar, b) a lunar eclipse on Earth?'

Asking pupils the deep questions in this activity will help the class to visualise the different positions of the Sun, Earth and moon during eclipses, and so consolidate their learning and clear up confusion.

Many more related activities can be found in our Earth in Space category on the website.

Science and geography activites for online learning

Earthlearningidea has produced many teaching videos and teaching workshops which both teachers and pupils can use either in the class room or online. Our workshops are designed for ages 11 to 16 but many are suitable for either younger or older pupils.


All the videos refer to the ELI activities they represent; these are linked to our website.
