ISC Practical Chemistry Class XI by S.P. Sharma, Dr Ajaya Baboo
“Those sciences are vain and full of errors which are not born from experimentation, the mother of all certainties”. A systematic ordering and reordering of knowledge is an essential part of teaching. Discussions, refine this expression of knowledge. However, to find out how the material world behaves, merely thinking about it will not serve our purpose. We must observe and therefore the need for experimentation.
In Chemistry it is only through experimentation, through the laboratory process, that the unifying principle can be developed and understood. Once we become familiar with these widely applicable and recognized principles, there remains no longer any need for endless memorization of innumerable chemical facts. The men who established the first laboratories way back in the Middle Ages, were known as ‘alchemists”. Today we laugh at them but their researches became the basis of a host of great inventions and discoveries. Who knows what wonderful new materials, our young experimenters may give to us, for future use.
