The traditional TOK diagram indicates four ways of knowing. Propose the inclusion of a fifth way of knowing selected from intuition‚ memory or imagination‚ and explore the knowledge issues it may raise in two areas of knowledge. The study of Theory of Knowledge (TOK) indicates four distinct ways of knowing: sense perception‚ emotion‚ reason and language; however‚ in this essay I will argue

Experiment #8 – properties of Alcohols and Phenols Introduction As has been mentioned before‚ over 20 million organic compounds have been identified. If each substance had to be studied as an entity completely separate from all the other substances‚ the study of organic chemistry as a whole would be impossible; that is to say‚ even more impossible than you currently believe it to be. Fortunately‚ the subject can be organized and it is often organized around the concept of the functional group
