Mr. Mendoza's 5-minute intro
  • • Yesterday we debated ethics. Today we build the scientific foundation for everything else in this course.
  • • Two words you will use constantly: anatomy and physiology. Anatomy is structure, physiology is function. A bone is anatomy. How that bone grows is physiology.
  • • The body is always working to stay in balance. That balance has a name: homeostasis. Today you will learn the loop that makes it happen.
  • • By the end of class your labeled homeostasis diagram will be in your notebook. That diagram is your first graded artifact.
Do this, step by step
  1. 1Read the teacher background notes on anatomy (structure) versus physiology (function).
  2. 2Define homeostasis and label the parts of a negative-feedback loop: stimulus, sensor, control, effector.
  3. 3Work the PLTW online task introducing homeostasis and the levels of organization.
  4. 4Sketch how body temperature is corrected when you get too hot.
  5. 5Submit your homeostasis loop diagram with each part labeled.
You'll be able to
  • • You can tell whether a statement describes anatomy or physiology.
  • • You can label every stage of a negative-feedback loop.
Know by the end
  • • Anatomy describes structure; physiology describes function. Both are required to understand disease (pathophysiology).
  • • Homeostasis is the maintenance of a stable internal environment; negative feedback is the primary mechanism.
  • • The feedback loop components are: stimulus, receptor/sensor, control center, effector, and response.

Day 2 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.

Do this: Return to Lesson 1.1 Beginning with Bones in myPLTW and complete the homeostasis and levels-of-organization online task; work through all required screens during class.

Complete

Mark the homeostasis task complete in myPLTW before submitting your labeled negative-feedback loop diagram.

How far to get

You finished the course-launch task Monday; by end of today the homeostasis task should also show complete in your progress bar.

Upload as evidence

myPLTW completion status visible to teacher, plus your dated notebook diagram.

All PLTW activities are completed inside the PLTW course environment — this page only gives direction. Submit producibles on Schoology.

The plan

Today's PLTW tracker

Check things off as you work, then submit. This tells Mr. Mendoza how you're doing so he can help the class. It does not replace turning in your producible on Schoology.

Today's PLTW target

Course Launch: PLTW access, BioDigital/Maniken routines, lab notebook, PPE/SDS, anatomy language, measurement norms. · Anatomy vs physiology, homeostasis

Return to Lesson 1.1 Beginning with Bones in myPLTW and complete the homeostasis and levels-of-organization online task; work through all required screens during class.

You finished the course-launch task Monday; by end of today the homeostasis task should also show complete in your progress bar.

This is how Mr. Mendoza sees the class keeping pace with PLTW. Be honest, it only helps if it is accurate.

1 · What you do today

🎯 Distinguish anatomy from physiology and explain homeostasis using a feedback example.

  • Read the teacher background notes on anatomy (structure) versus physiology (function).

  • Work the PLTW online task introducing homeostasis and the levels of organization.
  • Sketch how body temperature is corrected when you get too hot.
  • Submit your homeostasis loop diagram with each part labeled.

What to do if you were absent

If YOU are absent

Today is individual PLTW work, so do exactly what we did in class, from home: complete the same PLTW target above, then submit your Notebook check.

Open Schoology (CMSD) and keep going

How to get there: open the CMSD website, click Clever, sign in with your Microsoft (district) account, then open Schoology from Clever.

If MR. MENDOZA is absent
