Year 9 Science

Course Description:

Students learn about how ecosystems consist of living and non-living things and investigate how matter and energy flow through these systems. They use the theory of plate tectonics to explain global patterns of geological activity and continental movement. Students investigate how multicellular organisms rely on internal systems to respond to changes to their environment. They learn about how the central nervous system (brain and spinal cord) uses neurons to transmit electrical impulses through synapses. Students use the atomic model to describe the structure of the atom and explain how natural radioactivity arises from the decay of nuclei in atoms. This is followed by writing word equations to represent chemical reactions that involve rearranging atoms to form new substances. Students learn about how electric circuits are powered and the electronic components used in them. They describe how magnetic fields are used in the generation of electricity and the operation of motors.

Students develop questions and hypotheses and independently design and improve appropriate methods of investigation, including field work and laboratory experimentation. They explain how they have considered reliability, safety, fairness and ethical actions in their methods and identify where digital technologies can be used to enhance the quality of data. When analysing data, selecting evidence and developing and justifying conclusions, they identify alternative explanations for findings and explain any sources of uncertainty. Students evaluate the validity and reliability of claims made in secondary sources with reference to currently held scientific views, the quality of the methodology and the evidence cited. They construct evidence-based arguments and select appropriate representations and text types to communicate scientific ideas for specific purposes.
