This study has aimed to investigate the effectiveness of using negative example on the acquiring of some scientific concepts for the kindergarteners. To achieve the research objectives, scientific activities and pictured scientific concepts test were used. The study reached the following results: 1. There are no significant differences at (a = 0,05) between the mean scores of the experimental and control groups on acquiring scientific conceptsin pre-application. 2. There are significant differences at (a = 0,05) between the meanscores of the experimental and control groups on acquiring scientific concepts in post-application. The results were in favor of the experimental group. 3. The effectiveness of negative example on the acquiring of some scientific concepts for the kindergarteners. Finally, the study is ended with some conclusions and recommendations aspaying the necessary attentionto the kindergartners’acquisition of scientific concepts and the use of negative examples when presented.
