YEAR 8 TOPICS

The following is a list of the topics covered in Year 8 Science at Kings’. Pupils will, as in Year 7, be taught by two teachers: a Double Teacher and a Single Teacher. The subjects has been divided into discrete disciplines and, wherever possible, pupils will be taught by a teacher who is a specialist in that subject e.g. I will, as a Double Teacher, take a class for Physics (my specialist area) and Biology and the Single Teacher will take them for Chemistry which will be their specialist subject. I have attached links to a subtopic where there is further information available on BBC Bitesize for KS3 Science.
