In science last week, we found about about a twelve year old girl called Tarik who lives in Ethiopia. We watched her five mile walk to collect dirty water from a stream that is shared by animals and almost a thousand other people! We found out that the water that she takes to her family can make them ill because of the bacteria and dirt in the stream. As scientists who help people, we designed a simple filter which could help Tarik to clean her family’s water a little. Today, we made our own filter to separate materials and to clean the water. We then spoke to Beth from Severn Trent who taught us about the journey that water has to get to our taps and how they keep our water clean. We made a promise to make sure that we never waste the water that we have because there is only 1% of usable water in our world!
