The research problem was determined in the low level of children's acquisition of some scientific concepts, which led the researcher to use the thinking hand strategy in implementing the field of science in kindergarten to acquire some scientific concepts among second-level children. The researcher prepared the research materials: a list of scientific concepts, a book of activities, a teacher's guide, and also a research tool: an illustrated test of scientific concepts. The researcher used the semi-experimental method with two equal groups of pre and post measurements to measure the effect of using the thinking hand strategy on imparting some scientific concepts to the kindergarten child. The sample included 30 children from the kindergarten of 25 January Primary School in Balsafoura. The search tool was previously applied to both groups. Then the search experiment was applied using the thinking hand strategy, then the post application of the search tool on the two groups, then the results were statistically treated. The results resulted in the effectiveness of using the strategy of the thinking hand in implementing scientific activities on the acquisition of kindergarten children of some scientific concepts.
