This study aimed at examining the effectiveness of the inquiry learning model (ILM) to develop students' skills in carrying out experiments on the material of temperature, heat, and heat transfer. This study involved 21 students of class XI IPA-1 at SMAN 1 Kediri in the 2017/2018 Academic Year. The skills of students trained in carrying out experiments were the ability to assemble tools, the ability to read measuring instruments, the ability to record observational data, and the ability to present experimental results. The students' skills in carrying out experiments were assessed through observing physics learning activities with the material of Temperature, Heat, and Heat Transfer within 4 meetings. The findings show that the average score of the students' ability to assemble tools is 12 (very good category), the ability to read measuring instruments is 12 (very good category), the ability to record observation data is 13 (very good category), and the ability to present experimental results is 8 (good category). Further, the average score of students' skills in carrying out experiments on the temperature, heat, and heat transfer is 11 (good category). Thus, ILM can be an alternative to physics teachers in training the skills of high school students in conducting experiments in Classes and/or in the Laboratory.
