This volume includes 101 investigations and demonstrations that enable the teacher to illustrate the chemical principles being taught in the classroom. Other features include: historical information about the demonstrations where relevant; investigations and demonstrations focusing on a variety of topics and concepts, including energy changes, solubility, kinetics, acids and bases, electrochemistry and oxidation-reduction. Investigations are presented in an easy-to-read format, which allows readers to skim demonstrations for lists of materials and safety information. The book also includes references, structure drawings and equations where appropriate.
