- Claim, Evidence, Reasoning — make a claim, back it with evidence, explain your reasoning.
- SOP:
- Standard Operating Procedure — the exact steps to follow (especially in a lab).

💡 Big idea: Data from a blood-glucose graph can be used to identify when negative feedback is working and when it fails, as in diabetes.
- 0-8Distribute and preview the blood-glucose graph; orient axes and units
- 8-22Guided annotation: mark meal, peak, insulin active zone, glucagon zone
- 22-40Draft CER: write claim, select two data-point evidence entries, draft reasoning paragraph
- 40-58Peer review CER: check that evidence includes specific values and reasoning names negative feedback
- 58-70Revise CER based on peer feedback
- 70-80Final submission and individual reflection on diabetes connection
- • A graph of blood glucose after a meal tells a story about hormones working in real time.
- • Today you will read that story scientifically using the CER format.
- • CER writing is a core skill for the Anatomy/Physiology/Pathophysiology domain of the 072040 WebXam.
- • You will identify the peak, the correction, and the hormones responsible for each.
- 1Examine a graph of blood glucose before and after a meal.
- 2Identify where insulin and glucagon are most active.
- 3Write a claim about how the body restores normal glucose.
- 4Cite two specific data points as evidence.
- 5Add reasoning that connects evidence to negative feedback.
- • CER includes a claim, two evidence points, and reasoning.
- • Reasoning correctly names negative feedback.
- • A CER (Claim-Evidence-Reasoning) is the standard format for communicating scientific conclusions.
- • Evidence from a graph must include specific values and time points, not vague descriptions.
- • Pathophysiology of diabetes (Type 1 and Type 2) reflects breakdown of the insulin feedback loop.

Day 4 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Complete any data-analysis or CER reflection prompt in Lesson 2.2 Everything Endocrine on myPLTW associated with today's blood-glucose graph task; finish it before peer review.
Mark the data-analysis task complete in myPLTW after submitting your CER.
Feedback-model task is done; today the data-analysis task should show complete and your CER should be submitted.
