One of the skills that students must possess in order to face this challenge is critical thinking skills. These skills can be trained in a variety of disciplines, including physics. Through the implementation of a scientific approach in learning physics, students can practice critical thinking skills. In fact, the implementation of physics learning still used teacher-centered. Students are not given the opportunity to explore their understanding and thinking skills. So, there is a perception that physics is difficult. One of the materials that students consider difficult is heat and temperature. This research aims to describe students' critical thinking skills on heat and temperature in physics learning. The research method used is descriptive method. The research instrument was a critical thinking skill test in the form of essay questions and open interviews. The test was given to 33 students of class XI SMA Negeri 1 Krian Sidoarjo. Data were analyzed using descriptive analysis and the results of interviews were used to obtain in-depth information regarding students' critical thinking skills. In general, the results of the research show that the average critical thinking skills of students are still low. The lowest critical thinking skills of students can be seen in the category of inference and advanced clarification. Meanwhile, students' critical thinking skills in the category of basic clarification, building basic skills, and managing strategies and tactics were in medium criteria. Keywords: critical thinking skills, heat and temperature, physics learning ABSTRAK Revolusi industri 4.0 menjadi sebuah tantangan baru bagi dunia pendidikan. Salah satu keterampilan yang harus dimiliki lulusan pendidikan dalam rangka menghadapi tantangan ini adalah keterampilan berpikir kritis. Keterampilan ini dapat dilatihkan melalui berbagai disiplin ilmu, termasuk fisika. Melalui penerapan pendekatan saintifik dalam pembelajaran fisika dapat melatihkan keterampilan berpikir kritis siswa. Namun, saat ini pembelajaran fisika yang diterapkan masih berpusat pada guru. Siswa tidak diberi kesempatan untuk mengeksplor pemahaman dan keterampilan berpikirnya. Sehingga muncul persepsi bahwa fisika itu sulit. Salah satu materi yang dianggap sulit oleh siswa adalah suhu dan kalor. Penelitian ini bertujuan untuk mendeskripsikan keterampilan berpikir kritis siswa pada materi suhu dan kalor dalam pembelajaran fisika. Metode penelitian yang digunakan adalah metode deskriptif. Instrumen penelitian berupa tes keterampilan berpikir kritis dalam bentuk soal essay dan wawancara terbuka. Tes diberikan kepada 33 orang siswa kelas XI SMA Negeri 1 Krian Sidoarjo.
