This site gives an
opportunity for chemistry teachers from around the world to show, and
give to others, their experiment ideas on using simple materials instead of costly sophisticated apparatus.
If you can send me any ideas with pictures and notes I will be very
happy to publish them on this site. Copyright is all yours, there are no
hidden deals on this site, its all about sharing good low cost chemistry
experiments.

SITE PURPOSE EDUCATION -
online learning or 'self-private-tuition' using revision notes, quizzes,
practice tests involving SCIENCE in the areas of REVISING only the
CHEMISTRY-Earth Science-Radioactivity at Doc Brown's Chemistry Clinic via
HOMEPAGE in secondary school/schools, 6th form college/colleges,
academy/academies or home self-study and may help with 1st year undergraduate
university chemistry courses. Hopefully it will encourage interest and
understanding of Chemistry, Earth Science and Radioactivity in any country of
the world, though the site is written entirely in English. The website is
designed to help and unofficially support students/teachers revise-learn/teach
the chemistry for modular or co-ordinated examination science courses from UK
QCA based AQA, OCR (Oxford and Cambridge) Twenty First (21st) Century and
Gateway Science, Edexcel 360Science , Nuffield, Salters, Cambridge International
(CIE), London International, WJEC, CCEA exams etc. Also, national award
assessments-examinations for GCSE-IGCSE-KS4-O level-BTEC-NVQ applied, additional
and chemistry science courses and examinations, Advanced Subsidiary Level
GCE-AS-A2-IB-KS5-BTEC-NVQ National Chemistry assessment levels, KS3 SATs
Science-biology/chemistry/physics (SAT revision levels 3-5 or 5-7) and covers
much of the revising, learning and teaching chemistry of the International
Baccalaureate, K12 US grade 6,7,8,9,10,11,12,AP basic level examinations courses for the
national curriculum for secondary schools and colleges. The site does
not support the content of England, Wales or Northern Ireland primary
science KS1 or KS2. The notes should also provide some background theory
for a coursework assignment or a project. BUT please note that
my on-line revision notes and quizzes are no substitute for good classroom
teaching-lecturing and thorough studying of your own notes and textbooks, practicing past papers
and a copy of the syllabus which are readily downloaded from the
examination board sites, but I hope here and there they will lend a
tutoring hand on some topic, unit, module etc. For final revision you
have to be intellectually honest about what you don't know or follow, YOU have to
take the stuff to pieces, analyse what you do/do not understand
and reconstruct it so it all makes sense in the end. There is no other
way, there are no magic secrets on how to revise and learn, its mainly
down to hard work and just good old fashioned study and employing teach-yourself
strategies without the need for extra tutors and tutoring lessons. I also
think there is too much hit and miss revision using past papers (which I do
NOT supply) and not enough
systematic revision. I also hope it will help teachers in planning
lessons and developing schemes of work for science-chemistry. There are no
lesson plans on the site but there are plenty of quizzes to incorporate into
classroom activities whether photocopied or on electronic whiteboard projector
for use as self-tuition-assessment purposes and a variety of teaching and
learning styles and the images may be used in Microsoft Word documents and powerpoint projections.
The site seems to be used by a large number of home study tutors, particularly
the revision notes. An individual tutor may printout out the notes for
science-chemistry learning teaching-tuition purposes and for background material
for assignments and projects. I have no interest or time in producing WORD.doc or xxxx.pdf
revision notes files
of the notes at the moment. Neither have I time to write up many practical
laboratory experiments ('lab'-'labs') at the moment, but the notes contain lots
of background information of chemical reactions in terms of
observations-balanced equations-reactants-products-theory etc. I also find it
difficult to recommend specific exam websites or syllabus textbooks, it depends exactly on
what you need, what you have time for, and there are so many of them to choose
from and I do not supply past examination papers for classes. The sites
resources include revision notes, quizzes and worksheets which provide support
for home study or tuition for homework and coursework help e.g. science
investigations for any of the key stage courses indicated, but I do not supply
lesson plans. Dr W P Brown I 10-11-2007 |
