Basic chemistry, biology and physics terms, such as atom, molecule, mixture, cell and energy, are some common science vocabulary terms an elementary-aged child should know. Other concepts and terms to teach them are the meaning of a hypothesis, the meaning of data and how an experiment works.
Fundamental concepts and terms are important to teach elementary aged children so they can have a basic science foundation when they move into more complex subjects in middle and high school. In elementary school, they should be taught biological terms concerning the classification system for living things, such as kingdom, phylum and class, as well as parts and types of plants and animals, such as stamen, abdomen, python, wildflower and canine. Some physics and earth science terms and concepts they should be taught are temperature and the various forms of energy, force and work.
In 2012, a study was published in the journal "Early Education and Development" by psychologists Peter Marshall and Christina Comalli detailing how well elementary-aged children responded to being taught basic concepts in neuroscience. They learned vocabulary terms concerning the brain and its functions. The consensus was that teaching elementary aged children the sensory functions of the brain, such as thinking, feeling, seeing and hearing, helps them understand that the brain is malleable and can adapt to learning new things.
