An author who encourages young people to ""explore, question, experiment, discuss, read, study and think"" provides some basic tools in the form of clearly outlined and amply illustrated experiments in a variety of scientific fields. In each case, the necessary equipment is listed the way ingredients for a recipe appear -- in the very beginning and in the exact amounts. Various illustrations with short captioned paragraphs take us through the entire experiment, describing what to do and what is happening. Why the scientist evokes these particular reactions is a question open for further study and not the concern of this compendium. The experiments deal with such phenomena as air, water, electricity, measurement, light, heat, weight, etc., and the materials required in most cases are surprisingly simple to gather.
