This research is motivated by the textbook used by the teacher in the learning process that has not been able to help students learn independently, so students still have difficulty understanding the material. The purpose of this study was to determine the effectiveness and practicality of the science learning module on global warming material for seventh grade students of SMP Negeri 3 Tondano. This research is a development research with five stages, namely: Analysis, Design, Development, Implementation, evaluation. The results of this study indicate that based on the test based on the assessment of the current material I assessment 81%, material II experts obtained 85% including the category quite valid or suitable for use, while the media experts obtained 88% including the very valid category to use, the effectiveness test based on student learning outcomes with completeness of 0.8 including the criteria of high/very effective and the practicality test of the module obtained from the teacher's response with an average assessment of 4.7 is in the very good category. Based on the results of the study, it can be said that the science learning module on global warming material is feasible, effective and practical to use.
