‘Which element am I?’ poem challenge The poem below includes a variety of references to chlorine and its properties. The idea is for students to look at the text, firstly to identify the element and secondly, more importantly, to work out what the references to properties and uses relate to. The purpose is to put the concepts in a different form so that revisiting ideas becomes more engaging. Ed Walsh Chlorine Some might call me a little obsessive, the way I like to keep things clean, I am bacteria’s biggest foe, I am the king when it comes to hygiene. Whenever you go camping and you drink from a natural stream just pop me in your water bottle; one pill of me holds a germ-killing team! I’m used in anaesthetics and I help the pain to ease, you can spread me round your kitchen to avoid catching disease. I’m used to clean your bathroom, I can make PVC, face it kids, you’d find it hard to live your life without me. If that’s not enough to convince you that us elements are cool, remember next time you go swimming; that’s me who smells good in the pool! Ellie Walsh
