Case Closed: Bean Seed CER Full Lesson Pack

A complete, ready-to-teach Claim, Evidence & Reasoning (CER) lesson pack built around the Case Closed: The Bean Seed Test investigation. Students compare bean-seed results, identify a claim, select measured evidence, and write reasoning that connects the data to the claim. The pack teaches the CER structure before students apply it to new data.
