Artificial Photosynthesis Solar fuels and artificial photosynthesis Exploring Anaerobic Bacteria for Industrial Biotechnology Aerobic and Anaerobic Digestion and types of Decomposition 1 25th April Anzac Day Classification Brief understanding of history of classification. Understand principles of classification. Classification is dynamic and modified as more information collected. Linnaean Classification. KPCOFGS. With increasing specificity. Kingdoms are recognised on cellular differences. Human classification. Binomial Nomenclature. SHE 1: Classification systems are based on international conventions and are subject to change through debate and resolution; changes are based on all currently available evidence. Eucalypts but not Eucalyptus Classification of Kingdoms Explore anomalies such as ‘liger’ and mules Cut and stick activities – Older copies of Biozone Year 11 specimens - Describe the characteristics of major phyla. Distinguish the essential features that are used to classify them. (Web of Life Student Manual) Make and use multilevel dichotomous keys (these should be complex as many students have done this in lower school) Term 2: Ecology Week Content Activities/Resources Assessment and Homework 1 Ecosystems Define an ecosystem (communities interacting with each other and the environment), also define environment, community, population, habitat, Ecosystems are diverse, composed of varied habitats, consisting of a range of biotic and abiotic factors Species have tolerance ranges and this influences where these organisms can live. Biotic Factors can be inferred Measure all abiotic/physical factors in a local area using lab equipment and data loggers Describe the biotic factors present with in an ecosystem (organisms present or inferred (tracks, shells etc.) Comparison of two areas Understand the influence of abiotic factors on biotic factors Describe environment of different named organisms Use resources and information, for example local councils, Naturaliste Marine Discovery Centre, Perth Hills
The great Pacific garbage patch. 7 Y7-10 Examination Week Revision and Semester One Exam Semester One Exam 25% 8 Fire in Australia Fire is a dynamic factor in Australian ecosystems and has different effects on biodiversity. Many Australian species are adapted to fire to different extents and frequencies with the intensity and frequency of fires affecting species composition/biodiversity of an area. Many species rely on fire for continuation of their life cycle. Australians have used fire in ecosystem management with differing outcomes.

Environmental strategies, including revegetation and control of introduced species Management strategies, including protected and restricted commercial and recreational access SHE 4: Identification and classification of an ecological area as a conservation reserve also requires consideration of the commercial and recreational uses of the area, as well as Indigenous Peoples’ usage rights National Parks in Australia National Parks Council of Australia SHE 5: Australia’s Biodiversity Conservation Strategy 2010–2030 presents a long-term view of the future and the actions that need to be implemented to conserve biodiversity biosecurity/quarantine procedures - Explore political issues to do with siting/funding of gene and seed banks Investigate exploitation of genetic material from e.g. developing equatorial countries with high biodiversity Video - The Seed Hunter Download from Kings Park Activities Year 10 Biological Sciences Elective Course Term 3: Disease and Immunity Week Content Activities/Resources Assessment and Homework 1 Staff PD 18/7 Disease Define those organisms that are micro-organisms. Give examples of microorganisms. Define the term Disease. Diseases interrupt the normal functioning of the human body and what needs to be done to bring the body back to its normal state. KWL – What do you know about diseases? YouTube Video – infectious disease.
& 19/7 Briefly discuss diseases that have impacted history; black death, AIDS, SARS etc. List the ways in which infectious diseases can be transmitted. Consider how ideas about disease transmission have changed from medieval time to the present as knowledge has developed. Distinguish and give examples of infectious and diseases. Students classify diseases as either non-infectious or infectious such as ring worm, colon cancer, thrush arthritis, cholera, diabetes etc. Create a mind map showing three different ways diseases can be spread and the different types of diseases. 2 Ath Carn 29/7 Pathogens What are pathogens? Describe what a pathogen is. List the different types of pathogens. Discuss with examples of different types of pathogens. Investigate the different types of pathogens and explain their specific characteristics. Provide a bit more detail with bacterial and viral pathogens. Identify the different types of bacteria. Explain the difference between a virus and a bacteria. Compare the ways in which viruses and bacteria reproduce. JIGSAW strategy. – 6 groups of 5 or 4 Separate the class into different pathogen types – prion, virus, bacteria, protozoan, fungi and worms and arthropods. 6 groups of 4. Each person is to become an expert in their group and explain to the other groups their reporting of their pathogen. (to fill in a worksheet). Conclusion: Bring the class together and ask questions about the worksheet. Get students to share their results with the class. 3 Bacterial Growth Investigation Investigate the growth of bacteria on agar. Describe the general appearance, colour, size and shape of the groups or colonies on the agar plates Explain what bacteria is and provide examples of diseases caused by bacteria. Describe two ways in bacteria can cause disease and be useful. Research the particular ‘good’ and ‘bad’ bacteria: cause, symptoms and effects, treatment and relevant issues. Examples anthrax, leprosy, salmonella. Growing bacteria on agar plates. After growth period take pictures but DO NOT RE-OPEN PLATES. 4 Lines of Defence

Distinguish between chemical components of DNA in terms of their chemical composition. Understand how the chemical structure of DNA can explain its’ behaviour and properties. Use scientific knowledge and models to describe the chemical structure of DNA. Describe and explain how DNA changes during replication, and can identify factors that can influence the nature and rate of replication. Oct
14th Nov Definition of genetic engineering. Then define: A genetically modified organism is one whose genome has been modified or altered by gene manipulation and biotechnology – in particular recombinant DNA technology – to give it characteristics it does not have naturally. A transgenic organism is one whose genome has been altered by adding genes from a different species into its genome using recombinant DNA technology Gene therapy is the treatment of genetic disorders by replacing or supplementing defective genes (alleles) with normal, functional genes (alleles). Recombinant DNA technology Recombinant DNA technology Remove DNA from one organism and add it to the DNA of another organism Vectors what are they, different types of vectors Plasmid DNA Restriction enzymes Ligation enzymes Genetic Probes Production of genetically engineered insulin, treatment of disease such as cystic fibrosis. 7 21st Nov Y7-10 Examinations Semester Two Exam Semester Two Exam 25% 8 28th Nov DNA Cloning Reproductive cloning Transgenic organisms Therapeutic cloning Stem cells
