Very straightforward and written in a way that us mere humans of average intellect can understand. Good links to the different areas within science with little examples, research notes and reflection questions scattered throughout to consolidate information.
Aware that this is purely a science book but it is written very much from a discrete subject angle and I was a little surprised at being advised to use ICT to cover the areas that could nicely link in some useful maths work - and if planned so that the science and maths timeslots are together then the overlap of the two areas wouldn't mean a reduced amount of time analysing graphs and coming up with possible conclusions.
An excellent subject book but would have liked to have seen more cross-curricula links.
