On Friday last week we did a water cycle lesson and a water filtering experiment. In the lesson we learnt about how water gets cleaned and a little bit about the water cycle. Did you know water takes six hours to get completely filtered and clean! After we got into pairs and tried to make the cleanest water. The dirty water had dirt, newspaper, plastic and oil in it and the materials we got to use for a filter were sand, bark, paper towels and cotton balls. We tried all of these out and then used anything out of these to make the best filter. Me and my partner used cotton balls and paper towels. This is how it turned out.
