COMMUNICATING which may involve: arguing a position clarifying ideas and concepts constructing and using models creating diagrams creating presentations creating tables and graphs describing discussing thinking envisioning alternative futures explaining ideas and decisions exploring and elaborating ideas expressing points of view illustrating improvising and performing listening and questioning negotiating relating responding and debating retelling and restating summarizing and reporting supporting decisions using scientific report genres using scientific terminology . . . . |
| Historical and cultural factors influence the nature and
direction of science which, in turn, affects the
development of society. |
Science as a "way of knowing" is shaped by the ways
that humans construct their understandings. . |
Decisions about the ways that science is applied have
short- and long-term implications for the environment,
communities and individuals. . |
