Scheme of Work

Student version

1

A note to students using this scheme of work This is the course as we teach it at King Edward’s. And at this time especially each year group will be following the course in a slightly different manner and on different specifications (different exams at the end based on different content).

3rd and 4th years in this academic year, 2017-18, are studying the new specification based on the new 1-9 grading system. The 5th years are the last group to be taught the old specification based on the old A*-E grading system.

Hence only the course order for your current year group is correct for how you will/will have follow/ed the course through the full three years of study in this document. Although the difference between this year’s third and fourth years will be minimal.

Using this document The order of the whole course is on page 4.

Each specification point (what you need to be able to do) is listed in each topic section. This is essentially what you need to be able to do to in the examination.

Also importantly at the end of each section (Third Year, Fourth Year, and Fifth Year), is a list of relevant equations that you need to be able to recall from memory in the examination.

* The cohort sitting the 9-1 IGCSE examinations in summer 2019 studied the heat topic in their third year, however from Sept 2017 the third year allocation was reduced to 4 periods a fortnight, and to allow for this reduction in time the heat topic was taken out of the third year. Hence the cohort sitting the examinations in summer 2020 will be taught the Heat topic in their Fifth year.
