Students in Indonesia have problems in critical reading competence and understanding in the field of science in the form of misconceptions. This is indicated by the fact that students in Indo-nesia are only able to solve routine problems and will have difficulty when faced with unusual problems. In addition, this problem is also exacerbated by the unavailability of laboratory facili-ties and the process of critical thinking skills has not been implemented properly. The purpose of this study was to develop science learning tools to improve the critical thinking skills of junior high school students on additive and addictive substances. This study uses the development of learning tools with the Tessmer model. Starting from the self-evaluation stage, prototyping (vali-dation, evaluation/FGD, and revision), then field test. The learning tools developed include the syllabus, lesson plans, teaching materials, LKPD, assessment sheets, and LP to practice critical thinking skills. Data collection techniques were carried out through observation, teacher and student activities, documentation, and tests of learning outcomes and critical thinking. The trial subjects were 51 people who were divided into 3 stages of prototype testing with different stu-dents at each stage. The results of the development and research show that the learning tools de-veloped are considered practical so that they are feasible to use. The results of the research find-ings are that there is a tendency for the initial knowledge level of students to be weak and low concept understanding caused by interest in learning and low literacy levels.Keywords: guided inquiry, science, critical thinking skills, development research. AbstrakPeserta didik di Indonesia mempunyai permasalahan dalam kompetensi membaca kritis dan pemahaman pada bidang studi IPA dalam bentuk miskonsepsi.
