After our visit to the Marina Barrage we learned that one source of water in our homes is from the collected rain. However, we also know that when rain falls it picks up a lot of dirt and other particles that get mixed up with it. So how does it get clean before it gets to our homes? We all decided we would have a go at trying to clean water by creating a filtering system. We decided to try a sponge, a cloth and some cotton. At the end of our experiment, the children decided that cotton worked best, however, it was still too dirty! The next day some of our classmates took action! Sam brought in a coffee filter and a tea filter, and Aina M. brought a towel. We have yet to test the towel as she brought a very big one, she said she is going to bring a smaller one on Monday! Take a look at the slideshow to see what we found out!
