🔬 Help your students communicate scientific thinking with confidence! This Grade 6 Science worksheet is designed to teach students how to construct strong scientific explanations using the widely recognized Claim, Evidence, and Reasoning (CER) framework. Aligned with the Ontario Science curriculum, this engaging classroom resource encourages learners to support their ideas with evidence, explain their reasoning, and develop essential critical thinking and scientific communication skills. Whether you are introducing CER for the first time, reinforcing classroom learning, or preparing students for written scientific responses, this printable resource provides meaningful practice in an easy-to-use format.

📘 Why teach Claim, Evidence, and Reasoning? Scientific knowledge is built through observations, investigations, and evidence-based explanations. Students often know an answer but struggle to explain why they believe it is correct. This worksheet guides learners through the process of making a clear claim, selecting appropriate evidence, and connecting that evidence with logical reasoning. By practicing these skills, students become stronger scientific thinkers, better writers, and more confident communicators.
