Year 3 learn how to filter dirty water


Yesterday afternoon, Year 3 did some experiments to find out how to filter dirty water.  We got some REALLY dirty water and filtered it through coarse and fine sand.  We had lots of fun finding out whether coffee filters or paper towels did a better job of stopping the dirt from getting through.  We also enjoyed learning about how water from our rivers is made clean enough to drink.  (P.S. the pictures were all taken by a member of our class!)
