In Year 9, students consider the operation of systems at a range of scales. They explore ways in which the human body as a system responds to its external environment and the interdependencies between biotic and abiotic components of ecosystems. They are introduced to the notion of the atom as a system of protons, electrons and neutrons, and how this system can change through nuclear decay. They learn that matter can be rearranged through chemical change and that these changes play an important role in many systems. They are introduced to the concept of the conservation of matter and begin to develop a more sophisticated view of energy transfer. They begin to apply their understanding of energy and forces to global systems such as continental movement.
At Baldivis Secondary College, students look specifically at how systems such as the circulatory, digestive and respiratory system work together to create energy, how tectonic activity has shaped the local landforms and ways homes can be designed to reduce the heat loss. Student will also investigate how compounds and elements are structured at an atomic level and how humans can manipulate atoms to make them useful. Students will have the opportunity to be part of the colleges’ annual Science Fair.
By the end of Year 9 students grades and attitudes toward science are used as key indicators to available pathways for science in Year 10. It is these pathways which can affect the choices available to them in Years 11 and 12. As a result it is strongly advised that the importance of study and effort in class be emphasised at home as much as possible.
In Year 9 Students showing a keen interest and natural flair in the sciences will be provided a pathway to further extend their studies.
