Pure Substances and Mixtures Performance Task Outline

Pure Substances and Mixtures Performance Task

You are a Clean Water Non-Governmental Organization (NGO). Many developed and developing nations are facing a clean water crisis worldwide. You have been approached by the World Health Organization (WHO) to come up with a prototype and a proposal that will solve the water issues in one of these nations.

As a Group:

·                         Decide which country you wish to assist in finding a clean water solution.

·                         Research, plan design and build a device that uses 3 different filtration materials to separate a mystery mechanical mixture that will be provided to you by the WHO

·                         Your device must be able to fit in a 30cm³ box for efficient transportation

·                         You need to use the concepts that you will be learning in class when designing your prototype

·                         Write a reflection about your solution

Please note:

·         It is important to consider the specific geography of the country you are helping when designing your device

·         Keep in mind the environmental, social and economic impacts that your solutions may have

As an Individual:

·                         Research a method to remove the chemical and biological contaminants from a fresh water source

·                         Create a one page report using your research to support your ideas; the criteria for the report will be provided

Assessment

·                         Your device will be evaluated by how much clean water can be filtered in one minute

·                         A list of materials will be made available to your group; each material will have an associated cost – the cost should be considered when designing your prototype

·                         You will also be assessed based on how your design meets the needs of the nation you have chosen to work with
