Some assessment tasks have been updated to reflect current assessment practice and the nature of the discipline. An indication of time for the task is intended to provide greater comparability in the scope of the tasks across classes and schools, and to reduce School-assessed Coursework load for teachers and students. Outcomes Outcome 1 Analyse gravitational, electrical and magnetic fields, and use these to explain the operation of motors and particle accelerators Outcome 2 Analyse and evaluate an electricity generation and distribution system. Outcome 3 Investigate motion and related energy transformations experimentally, analyse motion using the Newtonian model in one and two dimensions, and describe the motion of objects moving at very large speeds using Einsteinian models.

An indication of time for the task is intended to provide greater comparability in the scope of the task across classes and schools, and to reduce School-assessed Coursework load for teachers and students. The proposed Outcome 3 task may be undertaken in Unit 3, Unit 4, or across Unit 3 and Unit 4, but will be reported as part of Unit 4 School-assessed Coursework and mirrors the current assessment task for Unit 4 Outcome 3. A template has been constructed for production of the associated scientific poster task to assist in staged completion and authentication of student work. Outcomes Outcome 1 Apply wave principles to analyse, interpret and explain wave phenomena. Outcome 2 Provide evidence for the nature of light and matter, and analyse the data from experiments that provide this evidence. Outcome 3 Undertake an investigation related to the motion of particles or matter, and present methodologies, findings and conclusions as a scientific poster.
