PICTON HIGH SCHOOL HSC Physics Special Relativity Due Date: (Week 8) - 27th November Mark: 40 Assessment Name: Special Relativity Weighting: 20 % SYLLABUS OUTCOMES TO BE ASSESSED: H1. evaluates how major advances in scientific understanding and technology have changed the direction or nature of scientific thinking H2. analyses the ways in which models, theories and laws in physics have been tested and validated H3. assesses the impact of particular advances in physics on the development of technologies H4. assesses the impacts of applications of physics on society and the environment H13. uses terminology and reporting styles appropriately and successfully to communicate information and understanding DIRECTIVES TO BE ASSESSED: TEXT TYPE: Review, Explanation, Referencing Describe, discuss, evaluate, explain TASK DESCRIPTION: According to most physicists, Special Relativity is a theory that has been tested and validated. Its principles are employed in designing applications such as GPS and televisions. Special relativity can even explain the colour of gold and the action of electromagnets. Discuss the principles of the Theory of Special Relativity and assess some of the evidence supporting this theory. Moreover, assess the impact of special relativity on society. ASSESSMENT CRITERIA: You will be assessed on your ability to: state the postulates of special relativity define key concepts such as time and mass dilation and length contraction present some evidence supporting the theory refer to several of Einstein’s thought experiments (“Gedanken” experiments) present relevant Physics formulae present examples of special relativity applied to technology and everyday life reference your findings Linked Dot Points: discuss the principle of relativity describe the significance of Einstein’s assumption of the constancy of the speed of light analyse and interpret some of Einstein’s thought experiments involving mirrors and trains and discuss the relationship between thought and reality analyse information to discuss the relationship between theory and the evidence supporting it, using Einstein’s predictions based on relativity that were made many years before evidence was available to support it 1 Assessment Policy – This is only a brief outline, you must check your assessment booklet for further details. Assessment tasks must be submitted on the due date. A zero mark will be awarded for work submitted late. If you know that you will be absent on the day of an assessment task, and have a valid reason, eg. compulsory work placement, representative sport, you must advise your teacher, IN WRITING, before the task is due. If the absence is unexpected due to illness, a doctor’s certificate will be required. Other absences due to exceptional circumstances may be deemed acceptable by the principal. Where an absence is considered justified, your teacher, in consultation with the Head Teacher, may decide a) to let you do the task at the first opportunity when you return or b) to give you an alternative task or c) to give you an estimate based on your performance in similar tasks. * Students who are absent due to participation in school representational activities must follow the above procedures or risk a zero mark.
