This research aims to develop learning science teaching materials based on scientific. The methods of this study are a research and development (R & D) by Borg and Gall. The instruments that used to collect data were observation sheets, interview guidelines, scoring questionnaires, and test (pre-test and post-test); To verify the effectiveness of the application of teaching materials using t-test. The results of this study can be concluded: 1) The results of the validation of learning experts obtained the value of 4.76 and a result of expert validation material obtained value 4.39. 2) For the effectiveness of teaching materials obtained an average score pre-test and post-test is obtained tobs = 7.9360> ttable = 2.024, it can be concluded that the test H0 is rejected. It means that the teaching materials developed can improve student learning outcomes.
