The first years have been studying physical and chemical changes. Today we did an experiment to show a useful chemical change and we made a nail turn pink by coating it in copper. We did this by firstly putting three spatula measures of powdered rock (copper carbonate) in the test tube, then carefully used a pipette to add acid a few drops at a time until the tube is half full. Next we dropped an iron nail into the solution and left it for about five minutes. Following that we very carefully poured the solution away and used tweezers to put the (hopefully pink) nail onto a paper towel. Mrs Duffy made a competition to see whose nail was the most pink. Fortunately my team won! Over all I have learned a lot about physical and chemical changes.
