The goal of general education is to comprehensively develop learners, including developing natural science capacity and the ability to apply natural science knowledge and skills to real life. In this article, we present the results of research on teaching STEM topics in the direction of developing students' natural science capacity through teaching the content "Density and pressure" in the program General Physics 2018. From there, discuss the feasibility and effectiveness of STEM education in developing natural science capacity for students.The goal of general education is to comprehensively develop learners, including developing natural science capacity and the ability to apply natural science knowledge and skills to real life.
