Hi guys! I'm doing a research about teaching elementary particles in the middle school, something that isn't the reality in my country. Despite of the research in Physics Teaching be a lot advanced, the proposals made by them are not applied in the practice of the teachers. I want to propose something that can be close of the reality in the schools, something that could be applied, but I'm having a really hard time to figure out which technologies are based on elementary particles concepts to let me capable to link the physics of it and their applicability in real cases, or make explicit the importance of teaching it to let students become capable to criticize the technologies or understand it. Can you give me examples of technologies and the importance of teach it in the middle school? Thanks in advance.
