In science, a special emphasis is placed on the research process in all grades. This includes making decisions about the generation and testing of ideas; prediction, measurement, data collection and representation; evaluation of sources of information; collaborative investigation; interpretation and communication of findings; evaluation and verification of findings and considerations relating to the social context of research. Students taking Biology gain detailed knowledge of living systems, especially at the biochemical level. Areas of investigation also include cellular organization, genetics, ecosystems and changes in organisms over time. The importance of science research is emphasized. Controlled experiments are performed and results are reported.
