1st DRAFT of My unofficial support for the
CHEMISTRY of the
WJEC (CBAC) GCSE SCIENCE COURSE
WJEC KS4 GCSE
Science-Chemistry
WJEC GCSE SCIENCE -
CHEMISTRY 1 * WJEC GCSE ADDITIONAL SCIENCE - CHEMISTRY
2 * WJEC GCSE SEPARATE SCIENCES - CHEMISTRY 3
syllabus-specification
PLEASE READ THE FOLLOWING VERY CAREFULLY
This unofficial
page I'm designing provides links to useful Chemistry sections of my site for the
Welsh KS4 WJEC GCSE Science - Chemistry 1, Additional Science - Chemistry 2 and
Separate Sciences-Chemistry 3 specifications. Over the past 7 years I've written lots of
notes for the previous GCSE courses, but I'm sure they will still prove useful
for the CHEMISTRY of the new GCSE-KS4 Science courses. PLEASE remember the notes are
NOT complete
and not just for your particular syllabus, but are designed to cover,
eventually, any Chemistry, Earth Science and Radioactivity of any GCSE syllabus
specification.
When you follow a link
you will find some useful information on the web page about the topic you are
researching. Sometimes the link goes straight to the relevant paragraph but
otherwise use the sub-indexes of key words or headings at the top of each page.
All the syllabus-topic-unit titles are taken from the official GCSE
syllabus-specification which you can download from the WJEC site. New word-fill worksheets and multiple choice (m/c) quizzes will be
adapted from 'old' ones and new ones developed through
2008.
Further note that the
new GCSE science-chemistry courses, particularly those in applied science,
require much more detail in some topics than will appear in my notes, however, I
hope my 'old' revision-information-research notes will help in some small way
for individual students. My chemistry research-information-revision notes ALL are being slowly revised and extended-updated
to cover the new chemistry material BUT I do not have time to deliver extended
responses to email questions and please do NOT ask for past papers.
