The research was 4-D models that are define, design, develop and disseminate stage was not implemented. Data analysis of the validation result was done theoretically and empirically. Validation results indicate that the developed of student worksheet was categorized very valid with the persentage reaches 3.65 for student worksheets 1 and 3.68 for student worksheet 2. Skill of process outcomes showed that students experience increased science of N-gain obtained 0.70 which was categorized as high.
