Title: Air
Synopsis: 1 (24 min): Introduces air as a mixture of gases in everyday use. Although air is essentially invisible, cooling it to extremely low temperatures turns it into a liquid. Gases in liquid form are used to demonstrate properties of oxygen and nitrogen. Real-
Title: Earth 1
Synopsis: 2 (35 min): Minerals and metals obtained from the earth. Looks at underlying chemical processes that lead to mineral-rich veins, refinement processes for extracting metals, analysis of ores for metals. Using a historical approach to mineral mining and pur
Title: Fire
Synopsis: 3 (32 min): Looks at fire as a chemical reaction: the chemistry of fuels and the physics of ignition. Looks at early fire-making techniques, at different fuels and their common energy component locked in their chemical bonds; the role of oxygen in releasi

Notes: NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
