Challenging interdisciplinary science experiments ; volume 2: Tasks of the European Union Science Olympiads 2008 2012 The European Union Science Olympiad (EUSO) is a unique multidisciplinary practice based team competition in the natural sciences. It was developed to provide young students with an opportunity to meet with their EU counterparts of a similar age and with a common interest in science. Through the EUSO they are provided with a platform to work in teams of three to solve relevant science problems of their time and to display their scientific capabilities. Each year in spring sixteen year old students from across the EU gather for one week to test their skills in biology chemistry and physics. This book contains the tasks presented in the five Olympiads of the years 2008 to 2012. The interdisciplinary nature of the tasks makes them appealing for use in the science laboratories of the schools of today. The book will also serve as a valuable resource of interesting and challenging experiments for young scientists everywhere. Challenge Interdisciplinary Science Experiments contains such diverse topics as energy from light silk fruit juice water crime investigation beer lenses amber and space exploration. In addition to a detailed description of the experiments including a list of the necessary equipment Stefan Petersen and Michael A. Cotter also provide model answers to the tasks.
