An ELI published in December 2013 was 'Be a mineral expert 4 – Recycle your mobile phone'.
Although the technology has moved on since then, the question still remains - "Why should I recycle my mobile (cell) phone?".
Did you know that smartphones contain a tiny bit of half the elements on the planet? Do you know about the super element indium
that is soft, melts and conducts electricity? It's believed we shall run out of these rare super elements in a decade. Will we then have to mine them in space? To answer all these questions, we recommend you watch the BBC 4 programme 'Secrets of the Super Elements'
in which Professor Mark Miodownik reveals the weird materials that have built our high-tech world.
New ELI+ today - 'Partial melting model and real rock; comparing a model with reality to develop understanding of the partial melting process'
This 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, shown in the activity. Bowen investigated the melting and crystallisation temperatures of a series of the minerals commonly found in igneous rocks, to discover the order of melting (and therefore their order of crystallisation).
Many more activities associated with igneous processes and plate tectonics can be found either by using the search engine or the index on our website.
