Abstract: The research aims to study the effect of using sound stereoscopes on developing some scientific concepts for kindergarten children. The research was based on the semi-experimental approach with two equal groups (experimental and control) due to its relevance to the nature of the research. The research sample consisted of (20) children (second level) from the Nazlat Zawiya Joint Kindergarten - Baba city - Beni Suef Governorate – Arab Republic of Egypt, whose ages range between (5-6) years, including boys and girls. Where the research experiment was done on the experimental group, taking into account the availability of the same number for the control group. To achieve the objectives of the research, the researcher prepared a list of some scientific concepts suitable for a kindergarten child, some sound stereoscopes to develop those concepts, and an illustrated scientific concepts scale to measure the extent of development of these concepts. To ensure the achievement of the research hypothesis of a measure of the extent of the effect of sound stereoscopes, and by analyzing and interpreting the results, the effect of using sound stereoscopes on the development of some scientific concepts for kindergarten children has been reached in a positive manner and stable effect on children.
