This research was categorized as an R & D research that aimed to develop Student Worksheets (LKM) in the Elementary Science Basic Concepts course. This course is used to instill students' critical thinking skills. The design developed in this study uses the 4D design (four D-Models) proposed by Thiagarajan, Semmel, & Semmel (1974), which consists of the following stages: 1) defining 2) planning, 3) developing. And 4) dissemination. The instruments used in this study were expert validation sheets and student response questionnaires. The data analysis technique in this study used expert validation data analysis and analysis questionnaire data of student response. The assessment from the material expert got a score of 4.67, which means a very good category. Then, the assessment results of the media experts get a 4,17 score means in the good category. The average value of expert validation (4.67+4.17):2=4.42 is in the very good category. Based on these results, the LKM based on 3N Science Basic Concepts (Niteni Nirokke Nambahi) was made feasible in the learning process. By implementing 3N-based LKM (Niteni Nirokke Nambahi) in learning, students' critical thinking skills increased. It can be seen from the results of the student response questionnaire. It was found that students gave a positive response with a percentage of 90.2%, which was in the 51% - 100% interval. These results are also supported by the student LKM answers, where the average value of 7 LKMs is 76.3. It means that the value has met the specified KKM.
