by Kevin Howard and Elaine Prisk Third Edition This book contains the detailed instructions necessary to enable students to complete 74 experiments on foods, textiles, detergents, and dyes. The experimental procedures have been clearly set out to enable students with little or no experience of scientific practical work to carry out the experiments with the minimum of instruction from the teacher. Each experiment is accompanied by a set of teachers' notes that provide greater detail on each of the experiments. Each of the experiments has been graded to one of three difficulty levels. The first level requires little or no specialised equipment, the second require more specialised equipment and greater practical skills, with the third level experiments requiring familiarity with laboratory work and a higher level of experience in the student. The aims and objectives of the book are four fold; ‰Û¢ to develop an investigatory, critical attitude of mind, ‰Û¢ to provide an understanding of the science and technology of food and textiles, ‰Û¢ to help develop a practical approach to experimental design and problem solving, and ‰Û¢ to foster a numerate as well as descriptive approach to experimentation. Reference to the teachers notes will enable the teacher to give additional guidance to students concerning particular experiments. The notes contain practical information on procedures as well as the equipment and reagents used. The details for these are also provided in the reference sections located at the back of the book. These sections cover; ‰Û¢ details of reagents for preparation, ‰Û¢ equipment used in all experiments, ‰Û¢ a glossary of scientific and technical terms used in the text, ‰Û¢ a bibliography of sources quoted in the text, and ‰Û¢ sample questions from several sources including new questions for this edition.
