In accordance with the demands of the curiculum in Junior High School integrated science implemented in an integrated manner, but the fact that learning science is done partially. Therefore, the researchers wanted to accommodate by making integrated science teaching tools. The purpose of this research is to produce devices with integrated science teaching guided inquiry setting valid, practical, and effective. Developed learning tools include student books and teacher handbooks. Research methods with descriptive analysis of the validity, practicality, and effectiveness of the learning. The results were obtained: 1) the validity of the study were very valid in the category with the validity of the book value of 3.57 and the student teacher handbook 3.63, 2) the practicality of the device is in the category of learning is very practical, with the value of the feasibility study on the practical category and very practical, the average value of the response of teachers and students' responses 3.66 and 3.87, 3) the effectiveness of the device, the average value of 85.16 and understanding of the concept of scientific performance appraisal form performance is above KKM and attitudes, so stated 100% complete. This means, the study met the criteria valid, practical, and efficient so that it can be implemented in a broad scope.
