The CER Sentence Starters and Resource is a structured guide that helps students write clear scientific arguments using the Claim, Evidence, and Reasoning (CER) framework. It provides sentence starters, guidance on finding evidence, and support for connecting claims to scientific principles. An example CER paragraph models how to structure responses, and writing tips ensure clarity and logical connections. This resource is ideal for science classrooms, supporting lab reports, experimental write-ups, and argument-based discussions in a scaffolded, student-friendly format.
