This week in ‘Sustainable Futures’, students were on mission to provide clean, safe water for all.
Imagine: You’re a volunteer with Engineers Without Borders and see first-hand the issues of accessing clean water, in countries ranging from Australia to Ethiopia.
Mission: Build a low tech/low-cost water filter using the money and resources that your assigned country has available.
- Build a water filter
- Filter a sample of dirty water
- Measure the effectiveness of your filter using the spectrophotometer
- Compare your results to other countries
In comparing the effectiveness of student’s filters with water standards in Australia, would we consider their filtered water to be drinkable?
Sound easy? Now add in all the possible interactions between countries. Can countries lend money or resources? Can countries beg, borrow or steal resources? Can countries buy all the resources and charge their own price? Can countries take advantage of different resource costs between countries?
