STEM education is an approach to teaching and learning that integrates the content and skills of science, technology, engineering, and mathematics (STEM) in learning about heat through science technology and society (STS) approach. To help Thai students understand to relationship between science, technology, engineering, and mathematics (STEM). This paper will discuss how to develop Lesson plan of the transfer of heat through Yuenyong (2006) science, technology and society (STS). Where learning activities were provided based on 5 stages. These are included (1) identification of social issues, (2) identification of potential solutions, (3) need for knowledge, (4) decision-making, and (5) socialization stage. The learning activities could be as following: The first stage, we use video clip of ‘The climate change of the Earth’ and identify the impact of the temperature rise inside their homes. Second stage, will need to identification of potential solutions by design Cool House. By using background and other knowledge will be proposed for various alternative solutions. Next stage, students will gain additional knowledge from scientific experiments on heat transfer. So that students have the knowledge or findings used to design the cool house. Fourth stage, students design and decided for the best solution of design cool house based on their scientific knowledge and other. Finally, Students presented their cool house in front of the classroom. Classmates and teacher comments, ask questions and suggestions for improvements to the house cooling and contribute to the mutual exchange of ideas. This paper may lead to the development of science teaching through the integration of science, technology, engineering, and mathematics (STEM)
