This was my millennium 'teaching & learning' project and Doc Brown (teacher) has been online since 2000! Its a big SCIENCE WEBSITE to get to know from a retired CHEMISTRY teacher (and some physics and general science for teaching and learning purposes), SO, use the appropriate INDEXES and Google custom 'Doc Brown's Site' SEARCH too! 'Doc Brown's Chemistry' (all material © Dr Phil Brown 2000 onwards) has lots of science revision notes & quizzes, mainly an e-learning website for chemistry, but includes some biology and physics too AND lots of 'unofficial' revision summaries for ALL the current English GCSE Science courses

Doc Brown in action in a Whitby Community College chemistry laboratory (now part of Caedmon College, Whitby) and out in the heather of the North Yorkshire Moors. Note the absence of a lab coat, hence the unseen holes in trousers, corduroy trousers are particularly susceptible to chemical attack!
