Revise: Scientific CommunicationA labelled diagram can show where the seeds and cotton wool go in the Petri dish; labels should identify the relevant parts rather than leave the reader to guess. A sketch graph can communicate a prediction, with water volume on the horizontal axis and number of seeds germinated on the vertical axis. It shows an expected relationship, not results already measured.
