I (1 ) was in Year 9 at college in Sale. One day at the lesson of Science we (2 )...(made) an experiment called Down the Drain. We (3 )...(had) a tub of water, and we (4 )...(put) in it all the different substances that pollute our water. It ( 5 )...(was) horrifying to see how bad the state of the water was once we (6 )...(had finished). In our next lesson we (7 )...(put) our polluted water through a simulated water cycle; when the water (8 )...(was coming out) the other end it (9 )...(was) clean and pure, but we (1 0 )...(learnt) that all the water can never be made reusable. This experiment (1 1 )...(was) a great one, and the teachers (12) ..... (should be congratulated) on giving us such a great opportunity to learn during this unit about pollution, global warming, climate change and the creation of our Earth; I (1 3 )...( think) more young children (1 4 )...(should be given) this opportunity as we are the future and without the knowledge of what is wrong we can do nothing to change it.
