Exploring the CER Model for Scientific Explanations

Mr. Furlong introduces the CER model, which stands for Claim, Evidence, and Reasoning, as a framework for scientific explanations. He explains each component: a claim is an answer to an experimental problem, evidence is data supporting the claim, and reasoning connects the two. An example using a commercial illustrates the model. The CER model can be applied across different subjects to enhance explanations.

What does the CER model stand for?

• Claim, Evidence, Reasoning

• Claim, Evidence, Result

• Claim, Experiment, Result

• Conclusion, Evidence, Reasoning
