Year 9 ScienceGive Me Energy!Scope and sequence summaryEnergy comes in different forms, and with its many forms comes its many uses. In this unit, students will learn about energy transfers and the different mediums that energy can be transferred using the wave and particle model. With many advantages, and unfortunately some disadvantages, Electromagnetic Radiation plays a particular important role in today society especially in communications technology and in medicine. Through various forms of research and presentation, students investigate the everyday uses of Electromagnetic Radiation in communication technology such as the mobile phone, and the important use of Electromagnetic Radiation in medicine. Electric energy is one of the most common forms of energy used in today’s society. Students will reflect on the use of electric energy in their daily lives and research how it has impacted on modern technologies.Unit overviewIn this unit, student will be able to research, design and conduct first hand investigations on and debate about the use of Electromagnetic Radiation in today’s society. Students will construct electric circuits and identify factors that influence electric energy.DurationWeeksOutcomesAssessmentSC55WS produces a plan to investigate identified questions, hypotheses or problems, individually and collaborativelySC57WS processes, analyses and evaluates data from first-hand investigations and secondary sources to develop evidence-based arguments and conclusionsSC58WS applies scientific understanding and critical thinking skills to suggest possible solutions to identified problemsSC59WS presents science ideas and evidence for a particular purpose and to a specific audience, using appropriate scientific language, conventions and representationsSC510PW applies models, theories and laws to explain situations involving energy, force and motionSC511PW explains how scientific understanding about energy conservation, transfers and transformations is applied in systemsStudent records and team reflections Practical investigations in practical booksProcessing and analysing dataStudent self-assessment of learning using a teacher-provided evaluation sheetUse of digital applications such as padlet, socrative, millennium, excel etcUse of marking rubrics to assess team presentationsPeer evaluations on experimentsSummative practical assessment taskBook marksWorking Scientifically OutcomesPlanning investigations (SC4-5WS)WS5.2Students plan?first-hand investigations by:a. collaboratively and individually planning a range of investigation types, including fieldwork, experiments,?surveys and research (ACSIS125, ACSIS140)Conducting Investigations (SC4-6WS)WS6Students conduct investigations by:b. assembling and using appropriate equipment and resources to perform the investigation, including safety equipmentProcessing and analysing data and information (SC4-7WS)WS7.1Students process data and information by:WS7.2Students analyse data and information by:d. applying numerical procedures and mathematical concepts and using digital technologies, where appropriate g. critically analysing the validity of information from secondary sources (ACSIS172, ACSIS206) Problem solving (SC4-8WS)WS8Students solve problems by:a. describing strategies to develop a range of possible solutions to an identified problemg. evaluating different approaches used to solve problems (ACSIS172, ACSIS206)Communicating (SC4-9WS)WS9Students communicate by:a. selecting and using in presentations, for different purposes and contexts,?appropriate?text types including discussions, explanations, expositions, procedures, recounts or reports c. using appropriate units for physical quantities and symbols to express relationships, including mathematical ones Literacy - Vocabulary Alternating currentAmmeterCircuit diagram Direct currentElectrical resistanceElectric cellCircuitCurrentGeneratorElectromagnetFuseMagnetic field Parallel circuitSeries circuitShort circuitVoltageVoltmetervoltsCataracts ConcaveConvexCorneaDispersionFocal length ImageIrisLaserLaw of reflectionLong sightedOptic nervePixelsPolarisedPupilRefractionRetinaShort sightedSpectrumTotal internal reflection AmplitudeAnalog CapacitorDiodeElectromagnetic radiationElectronicsFluorescentFrequency Gamma raysHertzInfraredLiquid crystal display (LCD)MicrochipModemPhosphorsSemiconductorTransistorultraviolet21971017145ContentSkillsTeaching and learning activities ResourcesRegisterCoreDeveloping & ExtensionPW1 b. identify situations where waves transfer energy.Context: Waves transfer energy.
