Separating materials

In Year 5, we have been discussing the environment.  We noticed that lots of rivers around the world are full of rubbish and we wondered how we could clean the water.  In science, we set up an experiment to use different equipment to separate dirt and rubbish from the water.  To begin with, it was quite challenging but then we realised that we needed to clean the bowl and jug that we were using before the next step.  We also realised that we mustn't pour too much liquid onto the filter paper, otherwise it escapes down the side of the funnel.  Eventually, we were successful and had clean water!  We know that we would need to take extra steps to make sure that the water is safe to drink but we are relieved to have removed all the dirt and rubbish.
