We are thinking of completely changing our science teaching for years 7 and 8. Currently they do a number of topics that sort of rotate through Chemistry, Physics and Biology. Things like solubility, forces and motion, respiration, magnets, chemical reactions, variation and adaptation. The new head of junior science is planning to swap to a topic based system that will have a mix of skills from each subject area. For example Forensics will have flame testing, microscopes, ballistics, chromatography, etc. Does anyone else do something similar? Or know of textbooks that may be of use?
