This research aims to describe the implementation of learning, the critical thinking skills of students, and the students' responses to guided inquiry learning on ecology material. This type of research uses a pre-experimental design with a one-group pretest-posttest design. The sample consisted of 35 seventh-grade students from SMP Negeri 14 Surabaya. The instruments used to obtain data were the learning implementation observation sheet, multiple-choice questions with reasons, and response questionnaires. The results of the learning implementation showed a mode score of 4, categorized as very good. After the implementation of the guided inquiry model, the average posttest score increased from the category of very poor critical thinking to critical thinking, with an average score of 68.07. The N-Gain score for the improvement of students' critical thinking skills was 0.5, categorized as moderate. Learning with the guided inquiry model on ecology material had a very good impact on the students' responses, with a percentage of 95.45%, categorized as very good. This study concludes that the application of the guided inquiry learning model can improve students' critical thinking skills
