Build Claim–Evidence–Reasoning (CER) skills in Grades 7–12 with this independent science practice worksheet. Students separate evidence from opinion, solve an everyday mystery, and transfer the structure to real data. Before your first big lab, students need to know the difference between real evidence and a personal opinion, and how to reason from one to the other. This back-to-school worksheet teaches the Claim"Evidence"Reasoning (CER) framework using scenarios teenagers actually relate to, then transfers the exact same structure to a real science data set so the skill sticks. WHAT’S INCLUDED • The three parts of CER - Claim, Evidence, and Reasoning - in clear student language • An Evidence or Opinion? sorting table that drills objective evidence versus subjective judgment • The Case of the Shutting-Down Laptop - an everyday mystery students solve with a full written CER • A Bridge to Science task that applies CER to real dissolving-rate data • A complete, ready-to-grade answer key with model responses WHY TEACHERS USE IT • 100% no prep - just print and teach • Works in Biology, Chemistry, Physical Science, Environmental Science, or introductory science • Not tied to any specific unit - use it any time you introduce scientific argumentation • Mature, high-school-ready design and tone for grades 7"12 Formats: print-ready PDF student worksheet plus separate answer key.
