STEAM education is an interdisciplinary teaching concept, which applies science, technology, engineering, arts and mathematics to practical teaching activities. This paper mainly takes Ohm's law in Chapter 17 of the textbook for junior high school grade 9 (full volume) of the people's education edition as an example, and uses the STEAM teaching concept to carry out the teaching design of Ohm's Law (Class 2), aiming at trying to explore how to use the STEAM teaching concept to carry out the teaching design in middle school physics and hoping to provide relevant reference for middle school teachers to use STEAM for teaching design.
