This study aims to validate the physics learning device for the subject matter of temperature, heat, and heat transfer using real experiments and virtual experiments method. Components of validated physics learning tools consist of syllabus, learning implementation plan, learning subject matter analysis, student worksheet, instructional media, and learning result test. The assessed aspects of the physics learning tool are format, content, and language. Expert validation comes from lecturers, teachers, and alumni consisting of 6 people. The conclusions of the assessment of the physics learning device generally fall into either category with a value of 3, so that the physics learning device can be used with little revision.
