Science is a story, a narrative, and scientists are storytellers. Teaching is quite possibly the ultimate in storytelling so if one is teaching science he/she is already storytelling. Using a story to set up a science topic is effective. One can engage the brains of the audience, paint the scene, let them realise why the idea or work is important and fire their enthusiasm. Telling a story at the start of an investigation can set the scene for the work, and can be used to give children a whole load of subtle hints as to what, or how, the investigation can be conducted. A strong believer in the effectiveness of storytelling, the author gives some advice on telling and choosing good science stories. (Contains 4 online resources.)
