Week overview - Everything Endocrine: hormones, feedback loops, and the blood-sugar model
Build a working model of a loop and use it to explain how and keep in a healthy range.
- 1List the major endocrine glands you can find on a body diagram and note one each releases.
- 2Define , , , and in your own words in your notebook.
- 3Set up the blood-sugar model with cards or tokens to represent glucose, , and .
- 4Run the model after a meal: show how rising glucose triggers and lowers it back toward set point.
- 5Run the model during fasting: show how falling glucose triggers and raises it back toward set point.
- 6Sketch the full loop and label the , sensor, response, and return to .
- • You will be able to match key hormones to the endocrine glands that release them.
- • You will be able to trace a loop from back to set point.
- • You will be able to explain how and balance .

- Hook: your body runs a silent chemical thermostat every minute, and today you build the model that shows how it works.
- Today's goal: prove you can trace a loop and explain the and balance with your model.
- This week's Monday bioethics debate: who should pay for when the price keeps people from staying healthy?
- Reminder: your graded feedback-loop organizer and model evidence live in the PLTW course shell, not on loose paper.
Do this: Advance the PLTW Everything Endocrine benchmark by completing the online evidence on glands, hormones, and feedback regulation in the course shell.
- • Endocrine glands release hormones that travel through the blood to target tissues.
- • A loop returns a variable like toward a set point.
- • lowers and raises it, working as a balanced pair.
- • Model a loop using , sensor, response, and set point.
- • Explain how and maintain glucose .

This explainer accompanies the PLTW lab protocol: watch it before lab.
Most days, this class is your PLTW coursework: and PLTW is online and individual. So being out usually just means doing exactly what we did in class, from home.
Open Clever, then myPLTWSign in to Clever with your district Microsoft account to open Schoology or myPLTW. Follow today's posted steps. If myPLTW will not open, use the posted alternative and tell Mr. Mendoza. Turn in your completed work through the Schoology assignment.
You can't do those from home: do this instead: Teacher-posted data/model packet, same objective. Supplemental: Khan: endocrine system; diabetes/blood sugar.
