Knowledge and Understanding Stage | My Assignment Tutor

Knowledge and Understanding Stage 5Science Years 7–10 Syllabus 57Living WorldOutcomesA student: ››analyses interactions between components and processes within biological systems SC5-14LWexplains how biological understanding has advanced through scientific discoveries, technologicaldevelopments and the needs of society SC5-15LW Related Life Skills outcomes: SCLS-17LW, SCLS-18LW, SCLS-19LW, SCLS-20LW, SCLS-21LWContentLW1 Multicellular organisms rely on coordinated and interdependent internal systems to respond tochanges in their environment. (ACSSU175)Students:a. describe some examples of how multicellular organisms respond to changes in their environmentb. describe how the coordinated function of internal systems in multicellular organisms provides cellswith requirements for life, including gases, nutrients and water, and removes cell wastesc. outline some responses of the human body to infectious and non-infectious diseasesd. describe the role of, and interaction between, the coordination systems in maintaining humans asfunctioning organismse. discuss, using examples, how the values and needs of contemporary society can influence thefocus of scientific research, eg the occurrence of diseases affecting animals and plants, anepidemic or pandemic disease in humans or lifestyle related non-infectious diseases in humansLW2 Conserving and maintaining the quality and sustainability of the environment requires scientificunderstanding of interactions within, the cycling of matter and the flow of energy through ecosystems.Students:a. recall that ecosystems consist of communities of interdependent organisms and abioticcomponents of the environment (ACSSU176)b. outline using examples how matter is cycled through ecosystems such as nitrogen (ACSSU176)c. describe how energy flows through ecosystems, including input and output through food webs(ACSSU176)d. analyse how changes in some biotic and abiotic components of an ecosystem affect populationsand/or communitiese. assess ways that Aboriginal and Torres Strait Islander Peoples’ cultural practices and knowledgeof the environment contribute to the conservation and management of sustainable ecosystemsf. evaluate some examples in ecosystems, of strategies used to balance conserving, protecting andmaintaining the quality and sustainability of the environment with human activities and needsKnowledge and Understanding Stage 5Science Years 7–10 Syllabus 58LW3 Advances in scientific understanding often rely on developments in technology, andtechnological advances are often linked to scientific discoveries. (ACSHE158, ACSHE192)Students:a. relate the organs involved in human reproductive systems to their functionb. identify that during reproduction the transmission of heritable characteristics from one generationto the next involves DNA and genes (ACSSU184)c. identify that genetic information is transferred as genes in the DNA of chromosomesd. outline how the Watson-Crick model of DNA explains:– the exact replication of DNA– changes in genes (mutation)e. describe, using examples, how developments in technology have advanced biologicalunderstanding, eg vaccines, biotechnology, stem-cell research and in-vitro fertilisationf. discuss some advantages and disadvantages of the use and applications of biotechnology,including social and ethical considerationsLW4 The theory of evolution by natural selection explains the diversity of living things and issupported by a range of scientific evidence. (ACSSU185)Students:a. describe scientific evidence that present-day organisms have evolved from organisms in the pastb. relate the fossil record to the age of the Earth and the time over which life has been evolvingc. explain, using examples, how natural selection relates to changes in a population, eg in thedevelopment of resistance of bacteria to antibiotics and insects to pesticidesd. outline the roles of genes and environmental factors in the survival of organisms in a populationAdditional contentAdditional content is not prerequisite knowledge for following stages, but may be used to broaden anddeepen students’ skills, knowledge and understanding in Stage 5.Students: debate why any investigation relating to biological research and involving or affecting animals,must be humane, justified and ethical describe the range of functions carried out by some endocrine (hormonal) glands in humans investigate how models can be used to predict the changes in populations due to environmentalchanges, eg the impact of fire or flooding, introduction of a disease or predator discuss the strengths and limitations of using models to make predictions about changes inbiological systems describe examples of advances in science and/or emerging science and technologies, in areasthat involve biological science such as dentistry, environmental science, biomedical engineering,physiology, pharmaceuticals or nanotechnology assess the role of the development of fast computers in the analysis of DNA sequences research how information technology is applied in bioinformatics
