註釋These beautifully photographed science activity books help young children take the first step toward understanding basic scientific principles. There's no better way for children to develop an understanding of scientific theories and laws of nature than to perform basic experiments where the outcome clearly illustrates these concepts. A child's natural curiosity and sense of fun are powerful educational tools.
