T he current research aimed at evaluating the effectiveness of a suggested science curriculum for hearing impaired primary stage students based on their needs to develop their preventive awareness. To achieve this aim, the researcher designed a list of the needs in whose light the suggested science curriculum for primary stage should be designed. This list was used to reach a suggested form for the curriculum to develop the dimensions of preventive awareness. A unit for sixth-year, primary stage titled ‘the sun is the source of all energies' was selected and prepared in detail out of the suggested vision. In light of the previous, a teacher's guide to teach the unit was designed. In addition, the researcher prepared the research instruments which included an achievement test, an attitude scale, and a test for the ability to deal in real life situations.  A group of participants was then selected to participate in the research and the instruments were applied to these participants before and after application. The results revealed that there is a statistically significant difference between the mean scores of the research participants in the pre and post-application of the achievement test, the attitude scale, and the test for the ability to deal in real life situations in favor of the post-application.
