Chemistry as a system of practices. An alternative for your teaching Authors José Antonio Chamizo Instituto de Investigaciones Filosóficas, UNAM, México Keywords: Chemical practices, chemical substance, analysis, synthesis, chemical entities. Abstract Chemistry is a system of scientific and technological practices, experimental, stabilized and taught in the same way in most countries. Throughout their history, fiercely realistic chemical communities were integrating entities (atoms, ions, orbitals) that allowed them to pragmatically explain their own practices. Different from those of physics, the practices of chemistry have their own method: analysis and synthesis, often in a dialectical combination. As a result of their practices, chemical communities add more than 15,000 new substances to the world every day, constituting a supernatural nature.
