Classroom practices of low-cost STEM education using scratch

Science, Technology, Engineering, and Mathematics (STEM) education is spreading in some countries. In Japan, it is hoped that STEM education is incorporated into school classes. STEM education is sometimes incorporated experimentally in school classes. It’s not performed in every elementary school yet. STEAM education usually uses robots and the equipment costs money. Only some teachers who get the equipment can perform STEM education classes. Therefore, I would like to propose a low-cost STEM education. In late years, I practiced some elementary school classes using Scratch. Scratch is a useful tool for programming education. I think that Scratch can also be used for STEM education. My proposed low-cost STEM education uses Scratch. In this paper, I show how to use Scratch in STEM education. Scratch can control drones and mobile robots. Low-cost drones and mobile robots are also present. I propose a class that combines this equipment and Scratch. It is also possible to conduct STEM education classes with Scratch alone.
