Preliminary Assessment Task 2011

Course: Chemistry

Date of Task: 7th of April

Period: Hand-In Task; Before School, 8:45 am

Venue: Student Office; Locked box and sign off

Topics: The Chemical Earth

Task

Content: (from Chemistry Syllabus document) 8.2.1.2.3: identify that the biosphere, lithosphere, hydrosphere and atmosphere contain

examples of mixtures of elements and compounds

8.2.1.2.4: identify and describe procedures that can be used to separate naturally occurring

mixtures of:

- solids of different sizes

- solids and liquids

- dissolved solids in liquids

- liquids

- gases

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

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 crude oil

Coal mining sand air

Aspirin from plant pigments salt water(drinking or salt)

Marking Criteria: You will be assessed on
