I'm a trainee on second placement. I have a year 10 group of very difficult kids who have basically opted-out of science. There's only 7 of them, but they're working on an entry level sub-BTEC course and getting them to do anything is a struggle. I'm finding that interesting demos etc can lead to a good discussion and then they'll take part. Next week I have to do something plants - what they do for us etc. I'm thinking of buying a venus fly trap and showing some carnivorous plants etc. After that I have to do something on carnivores and herbivores, how they're adapted and what predators are like. This will lead into food webs and then into sampling the organisms in a habitat (which we almost certainly can't do for real) It's all pretty dry for this kind of class. Has anyone got some ideas of stuff that might (just might!) spark a vague interest and get the point across?
