💡 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.

  1. 0-8Distribute and preview the blood-glucose graph; orient axes and units
  2. 8-22Guided annotation: mark meal, peak, insulin active zone, glucagon zone
  3. 22-40Draft CER: write claim, select two data-point evidence entries, draft reasoning paragraph
  4. 40-58Peer review CER: check that evidence includes specific values and reasoning names negative feedback
  5. 58-70Revise CER based on peer feedback
  6. 70-80Final submission and individual reflection on diabetes connection
Mr. Mendoza's 5-minute intro
  • 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.
Do this, step by step
  1. 1Examine a graph of blood glucose before and after a meal.
  2. 2Identify where insulin and glucagon are most active.
  3. 3Write a claim about how the body restores normal glucose.
  4. 4Cite two specific data points as evidence.
  5. 5Add reasoning that connects evidence to negative feedback.
You'll be able to
  • CER includes a claim, two evidence points, and reasoning.
  • Reasoning correctly names negative feedback.
Know by the end
  • 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.
