On-line chemistry CALCULATIONS for KS4 Science, GCSE/IGCSE Science-Chemistry and AS Advanced Level Chemistry (basic starter calculations)

ON-LINE CHEMISTRY CALCULATIONS

for F and H tier for KS4 science courses involving GCSE, IGCSE, BTEC, basic GCE-AS-A2-IB chemistry ~US grade 9-12

There are 16 linked sections listed below.

EMAIL query?comment e.g. spotted a silly error or request for type of GCSE calculation I don't seem to have covered?


useful alphabetical site indexIn these sections 1-16 you can study definitions of the terms used and examples of how to do chemical calculations.

Sections 2 to 6 illustrate the basic 'calculation' requirements for most UK GCSE Science students. Sections 1, and 7 to 15 cover most extra material for higher GCSE student in Science, triple award or IGCSE Chemistry.


Just click on the Ncyan.gifcalc4.GIFicons for notes and examples of a particular type of calculation to revise from.

To self-test yourself for revision, click on the icon click me! for a type in answer quiz, or click me! for a multiple choice quiz of 5Q's selected at random from the database, and there are two larger combined quizzes for foundation (F) or higher (H) GCSE/IGCSE students. (F/H suggest general foundation/higher revising guidelines for GCSE level)

Please note the Quiz feedback either relates directly to the Q [???-xx] OR it may be a typical worked example.

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 national science courses. Also covers, mainly via quizzes the UK National KS3 SATs Science-biology/chemistry/physics (SAT revision levels 3-5 or 5-7) and covers much of the revising, learning and teaching chemistry examinations 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 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 print 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 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 gcse 10-11-2007 *  ks4 science examinations gcse-igcse chemistry revision *  ks4 science examinations-gcse-igcse chemistry revision *  ks4 science examinations-gcse-igcse chemistry revision *  ks4 science examinations-gcse-igcse chemistry revision *  ks4 science examinations-gcse-igcse chemistry revision *  ks4 science examinations-gcse-igcse chemistry revision
