We realise that although we just have to turn on a tap for clean fresh water there are plenty of children in the world who cannot do this. Every day they walk miles to collect and then carry often very dirty water back to their families. We decided that we should find out what that is like. We took it in turns to carry just 12 litres of water in a variety of different sized containers - so that even the youngest could have a try. We discovered that water is very heavy, even when you only carry it for a comparativley short distance.
We made as many links as we could to the Geography, SPHE, PE curriculums.
When we had finished the challenge we told everyone at a big church meeting what we had done and why. They were so impressed they awarded us The Diocesan Schools' Environmental Prize.
Incidentally we didn't waste the water we carried. We drank some when it was still fresh. The rest we kept for gardening: very handy for watering in our prize - a holly shrub.
Then when the An Táisce representative came to talk about our Water Green Flag we told him all about our challenge too. He said that what we had done was really important because it helped us understand even more why we need to conserve water and not take it for granted.
