Doc Brown's TEACH YOURSELF CHEMISTRY
INTRODUCTION to teaching yourself basic chemistry
What is chemistry? The above animation tends to illustrate the populist view, but such a view of fizzing, pretty colours and flashes and bangs is frankly, only a small part of the subject we call chemistry - but, initially in the classroom, it is good fun and a good practical introduction! Unfortunately for many pupils/students its their only view of chemistry and if it doesn't live up to this 'view', it must be boring! BUT its rather a lot more things and relevant and interesting knowledge if you take the trouble to look!
e.g. How to transform one substance into another e.g. an acid + alkali (reactants) ==> salt + water (products). The practical techniques to carry out reactions and isolate the desired product - this involves apparatus design, separation and purification techniques. A fundament description of what a substance is, its structure and properties at the atomic/molecular level and developing theoretical models to explain and predict the properties of substances. How to investigate materials in terms of e.g. their constituent atoms and arrangement - molecular structure. Chemical analysis e.g. how to determine the % purity of a compound, the % constituents of a mixture. The development of innovative compounds e.g. 'smart' plastics, effective drugs, safe medicines. Environment chemistry - what are the chemical reactions that give rise to pollutants? What chemical changes occur to cause environmental harm? The list of present and future applications of chemistry has no limit, and environmental, health and ethical issues are becoming more and more discussed in the public domain - and rightly so.
Ten points to bear in mind while following my scheme!
How to teach yourself chemistry? hmm!!!
(the start of) THE SCHEME!
My initial version lays out a series of 'lessons' which I will regularly revise to make more coherent and by all means email me with suggestions for improvements. There is no set time for each lesson, that's up to you, and the quizzes and tests will give you some self-indication as to how you are getting on! They may or may not improve your confidence! In the multiple choice quizzes PLEASE read any feedback - part of the learning process AND if you think there is any sort of 'error' or poor design in a question PLEASE email me BUT quote the test AND the Q database reference number in square brackets [xxx].
Lesson 1. Some fundament basic ideas, concepts and definitions
Lesson 2. The physical states of matter - gas, liquid and solid
Lesson 3. Particle pictures in a wider context
Lesson 4. Physical and Chemical Changes - differences
Lesson 5. Separation of Mixtures
Lesson 6. Introducing Acids, Alkalis, pH Scale and Neutralisation
An excellent year of keen 6th form chemistry students!
Now then, who is doing the posing here!
Having been retired from classroom teaching since 2003 I have done home tuition in the North Yorkshire, Teesside and Cleveland areas in the North-East of England e.g. students from Whitby, Goathland, Scarborough, Pickering, Redcar, Middlesbrough, Saltburn, Guisborough etc. but now, I just work from home with a view to a second retirement soon to concentrate on the website! So, I'm hoping, as an experienced teacher (and student!), for nearly fifty years!, to put my experience fully into the website and via this page to produce a home based self-tuition system in chemistry from UK KS3 science-chemistry level, through GCSE/IGCSE/O level chemistry to advanced level chemistry (A/AS/A2 chemistry). However, with trying to develop other aspects of the site, progress on this page is slow, BUT, the work methodically continues as I plod on, and I may continue to do private tuition!
The distant digital memory of 'my' busy, but, untidy chemistry laboratory!
