This month in 2nd Class we learnt about Global Water as part of the Water Explorer programme. We discovered that the United Nations estimates an average human needs approximately 30 litres of water a day to survive: 6 litres of water for cooking and cleaning and 25 litres for bathing and keeping clean. In Ireland the average human uses 150 litres per day. In Africa and Latin America, the average person uses only 3 – 5 litres a day. We also discovered:
We learnt about a woman from Malawi called Mary and we found out how drought and climate change have had an impact on her country. Almost three million people in Malawi are experiencing food shortages due to the lack of rain. Trócaire installed a water pump in Mary's village and she said it had changed their lives.We decided to make 2 simple pumps in our class to see if we could transfer water from one area to another. We designed a toothpaste pump and a coin pump. Each of us got a chance to make the pumps. You can see pictures of our work below as well as videos showing both of our pumps in action.
We realise how lucky we are to have instant access to water and how we should be much more careful not to waste it, especially when the average person in Ireland uses 150 litres of water a day and some countries in the developing world only have enough water for 3-5 litres per person per day. In groups we visited all the classes in our school from 1st-6th class to share our project with them, talk to them about what we had learned and answer any questions they had. We also uploaded information, pictures and videos of our work to our class page and the Green Schools page on our school website.We are really looking forward to our next Water Explorer challenge!
