We believe in what we see and learn better by trying things out. This statement could not be more true when applied to a child's curiousity. The inherent need, in a child, to question and understand everything needs to be satisfied through guidance and provision of proper tools in order to improve knowledge. What better than to let the child test things out through small projects and experiments. The Science Projects' Encyclopaedia has been designed, written and illustrated with exactly this purpose in mind. Care has been taken to help the child learn, through experimentation, by using things which are easily accessible and available around him or her. This book opens up by counseling the child on precautions to be taken while experimenting and the things to be gathered to set up a small Home Laboratory. With a Glossary and Index in the end, this book is written in simple English and can be easily understood by a child, though the aspect of adult supervision has been overlooked.
