Uses terminology and reporting styles appropriately and successfully to communicate information and understanding DIRECTIONAL VERBS: Assess: Make a judgement of value, quality, outcomes, results or size Describe: provide characteristics and features Evaluate: Make a judgement based on criteria; determine the value of Use: a method or manner of employing or applying something TASK DESCRIPTION: Students are to create a research portfolio containing information about nuclear energy production how it is used in industry. The Portfolio is to address the following: Part A - Nuclear Chemistry (26 marks) Part B - Evaluate the discovery of radium made by Marie Curie, explaining the significant way it changed the nature of scientific thinking regarding the elements. ( 8 marks) Part C - Assess the advances in chemistry which were produced from Ernest Rutherford s discovery of transmutation ( 9 marks) Part D - Assess the impact that either the Chernobyl Reactor leak or the Fukushima Reactor leak has had on the society & the environment (10 marks) Part E - Identify an area of research currently being undertaken on one named radioisotope and describe usage. Do this for a) the medical field and b) the industrial field (20 marks) Part F Bibliography (2 marks)
