This resource explores different types or mineral deposits found in the Earth and focuses in particular on copper deposits called porphyry. A presentation looks at how these deposits are formed and mined. It then goes on to explain how geologists locate porphyry deposits using mapping, fieldwork, sampling,...

This Salters’ Chemistry Course unit from the University of York Science Education Group covered:
* The extraction and production of important materials from sulphide ores, iron ore and limestone.
* The use of relative atomic masses for determining the masses...

A Catalyst article about the rock cycle which is responsible for the formation of many different types of rocks and minerals. The article explores the formation of minerals, their chemical composition and internal structure together with the reason for mineral hardness. As silicates form a third of all known...

This animated video describes how Einstein’s field equations led to the cosmological constant, which was later shown to be incorrect.  However, Friedmann and Lemaitre found solutions to Einstein’s equations, if the universe was still expanding.  Hubble found evidence from the red-shift of galaxies that the universe...

Looks at the impact of global warming and to what extent humanity has contributed to this.  The animated video explains the greenhouse effect, and how greenhouse gases can absorb infrared radiation and then re-emit it.   It also looks at how the oceans become more acidic when carbon dioxide is absorbed from the...

This animation describes how gravitational waves were first detected, in 2015, at the Laser Interferometer Gravitational-Wave Observatory (LIGO), 100 years after Einstein predicted them.  Newton’s theory of gravity and Einstein’s theory of General Relativity are briefly described.  Taylor and Hulse showed indirect...
