Glossaries - GCSE chemistry
Glossaries Description -
Science, technology, engineering, and mathematics (STEM) is a broad term used to group together these academic disciplines. This term is typically used to address an education policy or curriculum choices in schools. It has implications for workforce development, national security concerns and immigration policy. The science in STEM typically refers to two out of the three major branches of science: natural sciences, including biology, physics, and chemistry; and formal sciences, of which mathematics is an example, along with logic and statistics.
