This booklet provides an understanding of science education for young children in terms of both a theoretical basis for planning and a selection of practical experiences. The theoretical and practical sections are organized separately, and readers are advised that an understanding of the theoretical approach is essential prior to implementing the practical ideas. The theoretical section asks and explores the questions: What is science? Why teach science to young children? What are the aims of teaching science to young children? The next section gives practical advice on planning science experiences and on encouraging science experiences that are spontaneous and unplanned. The last section presents a selection of science topics as a stimulus and starting point for developing science with young children. Each topic addresses some basic concepts and includes relevant science information, practical comments, and suggestions for science experiences. The science topics presented are: animals, air, electricity, the human body and health, light, magnets, plants, sound, and water. Contains 17 references. (AS)
