8.2.1.2.5: assess separation techniques for their suitability in separating examples of earth materials, identifying the differences in properties which enable these separations 8.2.1.3.4: identify data sources, gather, process and analyse information from secondary sources to identify the industrial separation processes used on a mixture obtained from the biosphere, lithosphere, hydrosphere or atmosphere and use the evidence available to: identify the properties of the mixture used in its separation identify the products of separation and their uses discuss issues associated with wastes from the processes used

Outcomes: P3. Assesses the impact of particular technological advances on understanding in chemistry P4. Describes applications of chemistry which affect society or the environment P5. Describes the scientific principles employed in particular areas of research in chemistry P7. Describes chemical changes in terms of energy inputs and outputs P12. Discusses the validity and reliability of data gathered from first-hand investigations and secondary sources P13. Identifies appropriate terminology and reporting styles to communicate information and understanding P14. Draws valid conclusions from gathered data and information

Hand-in tasks must be submitted at the student office before 8:45am. Tasks submitted after 8:45am will have a late submission receipt attached to them and signed by the Student Office Staff. This will be handed to the Academic Care Coordinator who will note its receipt and pass it on to the relevant KLA Coordinator. If you are unable to hand the task in on the due date, follow the illness / misadventure policy outlined in your assessment manual. This includes phoning the College by 8:30am and obtaining documented evidence.


Task Description: (copied from Chemistry Syllabus-skills) Data and Information on the above dot-points needs to be researched. In gathering and processing this data and information, you will need to use the following Skills: 11.1 a) analyse complex problems to determine appropriate ways in which each aspect may be researched 12.3 a) accessing information from a range of resources, including popular scientific journals, digital technologies and the internet 12.3 b) practicing efficient data collection techniques to identify useful information in secondary sources 12.3 c) extracting information from numerical data in graphs and tables as well as from written and spoken material in all its forms 12.3 d) summarising and collating information from a range of resources 12.4 d) evaluate the relevance of first-hand and secondary information and data in relation to the area of investigation 12.4 e) assess the reliability of first-hand and secondary information and data by considering information from various sources You will then analyse and present the data and information. In presenting and analysing this data, you will need to use the following Skills: 13.1 a) selecting and using appropriate text types or combination thereof, for oral and written presentations 13.1 b) selecting and using appropriate media to present data and information 13.1 c) selection and using appropriate methods to acknowledge sources of information 14.2 a) identifying and explaining the nature of the problem 14.2 b) describing and selecting from different strategies those which could be used to solve a problem 14.2 c) using identified strategies to develop a range of possible solutions to a particular problem 14.2 d) evaluating the appropriateness of different strategies for solving an identified problem 14.3 b) propose ideas that demonstrate coherence and logical progression and include correct use of scientific principles and idea

TASK: You need to select one mixture from the list at the bottom of this section (“Topics”) Identify data sources, gather, process and analyse information from secondary sources to identify the industrial separation processes used on your chosen mixture and complete the questions below 1. name the mixture (1) 2. describe the industrial separation process (3) 3. identify and explain the properties of the mixture used in its separation (4) 4. identify and describe the products of the separation and their uses (4) 5. Include a flowchart that clearly shows the process, inputs and outputs, properties affecting separation, uses of outputs, waste products. (5) 6. Discuss issues associated with wastes from the separation process used (4) 7. Include all relevant diagrams, pictures etc with appropriate referral to text (3) 8. Assess the reliability of the reference sources you chose (3) 9. Bibliography sighting a range of resources (3) Topics: Blood sewage Coal mining sand Aspirin from plant pigments

crude oil air salt water(drinking or salt)
