Year 10 Physics Learning and Teaching Plan 2010 Area of Study: STELR Project 75 minute lessons, Teaching Sequence Pre-test Lessons Corresponding notes and resources Pre questionnaire ideally conducted before the course begins. Students entered into STELR portal through student test administration and pin numbers allocated. Introduction (4 lessons) 1. Welcome to the study of physics. Physics movie as introduction. Explanation of STELR project. 7:30 report 15 segment on Australia’s sustainability given the projected 60% population increase. List problems identified and brainstorm possible solutions. Computer room to pretest if not already completed. 2. Teaching about global warming , greenhouse effect, ozone depletion and climate change. Natural Greenhouse Effect Enhanced Greenhouse Effect Main contributors to Enhanced Greenhouse Effect Likely environmental changes to global climate Ozone layer Ozone depletion Likely environmental changes due to ozone depletion Ozone depletion and Greenhouse Effect Distribute notes, use websites to supplement the written material students expected to have explored the sites and made their own notes. Teaching about energy. Images of energy – a class discussion Class discussion, some key energy ideas. Conservation of energy 3. Teaching about energy continued... Energy storage ideas of either kinetic or potential. Kinetic = energy stored in a moving object and is related to the speed and the mass. 11 weeks = 22 lessons, (assume 20) Assessment / homework Emphasise the pretest is only to gain an idea of what they already know so we can better structure the course to their needs. If pretest already completed – class discussion works well. Usually plenty of opinions! STELR website http://www.stelr.org.au Clickview 7:30 report 27/01/2010 15 minute segment.

Whenever anything happens or changes there is an energy change. Perhaps ask a Teacher Librarian to run this section Pages 28 -31 Student workbook Images of Energy powerpoint show. Document1 13/05/2010 Discuss the use of the notemaking template as a research tool, appropriate for all areas of study. Encourage students to use more than one site and talk again about the reliability of websites and how that can be judged. Notemaking grid from Kilbreda Library website: http://kilbreda.vic.edu.au/library/research.html Key Ideas about Energy handout or use p9 Student workbook. Reflection This is the perfect place for the energy efficiency worksheet. Can give as homework or leave it until later in Potential = related to an object’s position relative to other ‘connected’ objects. Energy as the capability to make something happen Discussion questions about hammer, nail, wood... What is the actual job? What are the different forms of energy involved? Where has there been a transfer of energy? Where has there been a transformation of energy? What is the useful energy? What is the energy that is not useful? What is useful? If there is conservation of energy, where has it gone? What energy changes occur for each object in the system, ie arm, hammer, nail, wood and surroundings. Introduce Sankey diagram Units to measure energy, joule Units to measure power, watts 4. Practical Investigation – the efficiency of a bouncing ball. ** Production of a biofuel from fermentation of a sugar solution to produce ethanol Sampler Activities and further investigation into Global Warming (4 lessons) 5. Recap Global warming from Y9 Science Clickview : Renewable Fuels Concept mapping of Energy, Renewable Energy and Global warming ** Sampler lessons A flic flac’s energy changes A simple electric generator A falling mass produces electricity Hydroelectricity Carpenter drives nail into a block of wood. Two important boundary conditions to consider 1. The objects that make up the system 2. The starting point and end time of change Start = hammer held stationary above block at highest point. End = hammer and nail have come to rest. Use the Investigation Planner in the STELR resource book. Discuss best ways of presenting graphed data. First half of lesson making ethanol. Discuss the chemistry involved. Ie sucrose to glucose then glucose to ethanol C12H24O6→2C6H12O6 then C6H12O6→(+yeast as catalyst) 2C6H5OH + 2CO2 Computer room to complete another notemaking template on biofuels What is biofuel / biomass? the unit if an extra is going to be needed. Needs to be attempted before the detailed investigations occur. Watch STELR global warming DVD (10 min) Complete summary worksheet together at the end of class. Construct a concept map using the terms on the list and the marking scheme (p28. Teacher Resource Book). 2010/year10/STELR/concept map task.pdf Images of energy not very good, cow eating grass etc. A trampoline would be a better image. Needs revision Investigation planner completed & graphed plus a Sankey diagram. pp 58-59 Student workbook Notemaking template on biofuel competed. Concept map completed New 2010 STELR focuses on wind and solar. This is very interesting – but may need to cut it for time reasons. Supply modelled concept map for discussion. Laminated class sets available from DBD, set up as stations around the room. Burning the fuels for the biofuels must be done in a fume cupboard for the firelighter in particular. Needs risk assessment. Talk with Y9 team about lead in to this topic. Inconvenient Truth? Change these sampler activities once the new equipment arrives. Use data loggers to collect data with the temperature probe for the biofuels experiment, either the CBL’s or Nova 50000 Students love the biofuels sampler but I Document1 13/05/2010 Photovoltaic cells in circuits Wind student sampler (longer) Biofuels student sampler (longer think it takes too much time! 6. NEW STELR SAMPLER LESSONS 1. Mystery toys 2. Hand cranked generator 3. Chemical battery 4. Pelton wheel 5. Commercial battery 6. Wind Turbine 7. Solar panel 8. Mini kettle pp 12 – 25 Student Resource Booklet condensed into double sided page questions to be completed in the student module. 2010/year10/STELR/energy_transformations_investigations.docx Circuit workout (4 lessons) Only need all 4 lessons if students have not undertaken analysis of electric circuits before. 7. 8. 9. and 10. Series and parallel circuits. Measuring current and voltage in series and parallel circuits. Three lessons practical time, one lesson to complete any remaining prac work and to start the discussion questions Appendix 6, 7 and 8 in the STELR Handbook – photocopy for the students. Work in pairs and put two pairs together as a group to discuss results and compare findings. In Depth Investigation (4-6 lessons) 11. to 14. or 16. inclusive.

Complete activities and answer questions. This can take just 1 lesson to familiarise with equipment. Focus is on energy transformations. Doing it this way will be a time saver. Circuit workout booklet completed Good to read through the theory with students if they have no experience with electricity. Particularly, take care when using multimeters not to continually blow the fuse by putting an ammeter in parallel or a voltmeter in series. Extension activity 6. Power and Efficiency delivered by a solar panel pp 73 – 84 Instructions laminated and put out as a round robin activity. Eight groups of three, 8 minutes at each activity. 2010/year10/STELR/circuit workout scanned booklet.pdf Booklet completed and submitted. Only 3 lessons in first rotation to complete this due to lateness of equipment. pp 106 – 109 Students can choose whether they want to be a solar or a wind expert and investigate accordingly. Preparing for presentation Lux meter not working well. With 3 lessons – graphing an option for a “B” if done well. No time for these in rotation 1. Assessment rubrics available in STELR teacher handbook and on website. Presentation assessed No presentations Document1 13/05/2010 (2 lessons) Test Other lessons to fit into the program somewhere: Critical Thinking Analysis and Careers Focus and / or data analysis activity Distillation of ethanol An Inconvenient Truth Design Challenge Energy Efficiency worksheet Ideally these are oral presentations to the class. They can be written and assessed by teacher if out of time. Students present their finding in a team about the operation and efficiency and suitability of solar and wind generated electricity. 21. Formal test to assess competency in electric circuits and renewable energy forms. Critical Thinking task about death of bird life through wind turbine construction. by teacher and peer. possible first time around. STELR on line test available in near future Renewable energy test (Including a practical electrical circuit component) Revision sheet for students outlining topics covered and resources they should use for revision. New test written. Check with STELR online test for supplementary testing. Computer room, headphones to listen to audio component. Use the careers focus sheet from the STELR handbook and email the critical thinking activity or data analysis activity Critical thinking better than data analysis This works as an extra Separate the yeast from the ethanol solution by filtration then distill the solution to separate the ethanol. Recall separation of mixtures from Y7 Science. Lab Tech to undertake the distillation as a demo, students can do their own filtration. Available on Clickview – great to leave as an extra Duration 93 minutes. Could be included anywhere in the program This is the best thing about this project, it requires about 4 lessons and until we condense the above content we cannot find time for it. Measuring energy Using common prefixes (k, M, G, T) Measuring Energy Efficiency Students work in a team to apply their learning about solar and wind energy to a real life application, sailing to an island on a renewable energy fuelled yacht. Not sure how we can use this ethanol – need to demo distillation Needs work!!!! This works as an extra for 40-50 minutes. Note: The shaded boxes are different approaches tried in early 2010. Recommend not to continue these in the course, but have left them there for future reference. Document1 13/05/2010
