Classic Chemistry Demonstrations is an essential, much-used resource book for all chemistry teachers. It is a collection of chemistry experiments, many well-known others less so, for demonstration in front of a class of students from school to undergraduate age. Chemical demonstrations fulfil a number of important functions in the teaching process where practical class work is not possible. Demonstrations are often spectacular and therefore stimulating and motivating, they allow the students to see an experiment which they otherwise would not be able to share, and they allow the students to see a skilled practitioner at work. Classic Chemistry Demonstrations has been written by a teacher with several years' experience. It includes many well-known experiments, because these will be useful to new chemistry teachers or to scientists from other disciplines who are teaching some chemistry. They have all been trialled in schools and colleges, and the vast majority of the experiments can be carried out at normal room temperature and with easily accessible equipment. The book will prove its worth again and again as a regular source of reference for planning lessons.Chemistry demonstrations have an important role to play in teaching. They provide a visual attraction to the fun of chemistry and are a teaching aid for use with students. - They are often spectacular, stimulating and motivating - They allow students to see experiments which they would not be able to perform themselves, for reasons of skill, safety, expensive apparatus and materials or limited resources such as fume cupboards - They allow students to see a skilled practitioner at work The ideas behind the demonstrations in this book come from many sources. Some are original, but most have been collected from literature and from chemistry teachers all over the world. As many come from more than one source, in general no attempt has been made to acknowledge the source - some were suggested by as many as thirty diffló2
