3TD water education – classroom water awareness activities
Cities and water
We never know the worth of water till the well is dry. - Thomas Fuller, 1732.
Old proverbs have frequently made reference to the value of water. Water is a precious resource, and many people in the world lack an adequate supply of good clean water. Even people in wealthy nations sometimes face water shortages. Many water experts suggest that global warming will lead to increasing water shortages in many parts of the world. Meeting the water needs of the world’s growing cities is a major challenge.
There are four main ways to meet a large urban population’s demand for good quality drinking water:
- Capture surface fresh water during the natural water cycle
- Tap into natural supplies of underground water
- Desalinate sea water
- Reduce the population’s demand with more efficient water practices
Through the course of history and in different environments, human water use has varied greatly, from an average consumption of less than 10 litres per person per day, to a consumption of over 300 litres per person per day. In order to foster practical water awareness the 3TD program is developing five class room study modules. Each module focuses on an aspect of urban water use, and includes a practical hands-on class-room project.
Five classroom water-awareness activities
The following suggested classroom study topics and activities cover provide practical information useful for people of all ages, but the philosophy behind 3TD is to promote water-awareness through schools. The following suggested classroom activities could be tailored to suit students from years 5 through to year 10. Each module focuses on a different aspect of urban water use and where possible includes a hands-on practical class-room project.
