1 Year 9 Term 2: Body Systems and Responses ASSUMED KNOWLEDGE STAGE 4 OUTCOMES SC4-14LW relates the structure and function of living things to their classification, survival and reproduction Check Date SC4-15LW explains how new biological evidence changes people s understanding of the world LW1 Multicellular organisms rely on coordinated and interdependent internal systems to respond to changes in their environment. (ACSSU175) 5LW1a. describe some examples of how multicellular organisms respond to changes in their environment identify that living things are made of cells identify that substances move into and out of cells distinguish between unicellular and multicellular organisms explain why multicellular organisms require specialised organs and systems (limitations of diffusion) describe some examples of how multicellular organisms respond to changes in their environment: eg. animals v s plants- temperature and water response ectotherm v s endotherm freshwater fish v s marine fish hibernation 5LW 1b. describe how the coordinated function of internal systems in multicellular organisms provides cells with requirements for life, including gases, nutrients and water, and removes cell wastes Compare rates of diffusion in 3cm cube v s 1cm cube of pp/naoh agar in HCl OR using iodine/ki and starch observe that small molecules pass across semi permeable membrane, such as iodine while large ones don t, eg starch identify that tissues, organs and organ systems in multicellular organisms consist of different types of cells explain that systems in multicellular organisms serve the needs of cells Digestive system describe the features and role of the digestive system in maintaining humans as Respiratory system describe the features and role of the respiratory system in maintaining humans as Highlight conditions necessary for gas exchange: moist membrane, thin membrane and concentration gradient Circulatory system describe the features and role of the circulatory system in maintaining humans as 1

2 Excretory system describe the features and role of the excretory system in maintaining humans as : Sheep kidney dissection Skeletal system describe the features and role of the skeletal system in maintaining humans as 5LW1c. outline some responses of the human body to infectious and non-infectious diseases Distinguish between infectious and non-infectious diseases Define pathogen Distinguish and describe the main features of bacteria, virus, fungi, protozoa and prion Students in small groups to research and present information on one named infections and non-infectious disease. Include, cause, symptoms, treatment, prevention, interesting facts and figures : Modelling the spread of infectious diseases Describe the body's defense to invading pathogens. Include: 1st line of defence: Skin, Cilia, Mucous lining. nonspecific 2nd line of defence: Phagocytosis, Inflammation. non-specific 3rd line of defence: T and B lymphocytes. specific Outline why no cure exists for HIV/AIDS. Relate to function of T and B lymphocytes. Outline the historical developments, and describe briefly how vaccinations and antibiotics work : Choose either vaccination or antibiotics. Critically analyse information from secondary sources. Write a persuasive news report that addresses multiple viewpoints and concludes with a recommendation for action. 5LW1d. describe the role of, and interaction between, the coordination systems in maintaining humans as Describe the features and role of the: nervous endocrine systems in maintaining humans as Describe using a named example: stimulus-receptor-messenger-effector-response Response time. In pairs, drop 30cm ruler between partners fingers and record length taken to catch. Repeat, average and compare with other students Describe the flight or fight response and discuss its likely purpose Students are to research a named hormone and present information to the class. Include: Name Function 2

3 Health problems if hormone not functioning correctly 5LW1e. discuss, using examples, how the values and needs of contemporary society can influence the focus of scientific research, eg the occurrence of diseases affecting animals and plants, an epidemic or pandemic disease in humans or lifestyle related non-infectious diseases in humans Students are to present information on how the values and needs of contemporary society can influence the focus of scientific research, Eg. the occurrence of diseases affecting animals and plants, an epidemic or pandemic disease in humans or lifestyle related non-infectious diseases in humans.

Choose from the biomedical engineering, immunology, pharmacology, nuclear medicine or nanotechnology fields[we]. The career must not have existed 20 years ago 5LWadd1 debate why any investigation relating to biological research and involving or affecting animals, must be humane, justified and ethical Class discussion/debate: Debate why any investigation relating to biological research and involving or affecting animals, must be humane, justified and ethical.
