Week overview - Master the Morgue: body systems, tissues, and toxicology evidence

Sep 28–Oct 2

Examine samples under the microscope, connect organ systems to , and read toxicology evidence to reason about a .

Week arc
  1. 1Open the Unit 1.2 task in your PLTW shell to see what evidence is graded.

Get oriented

Quick intro to the week

  • The morgue is where the body's own systems become the evidence, and reading is a skill real pathologists train for years to master.
  • Today's goal: use and toxicology data together to reason carefully about how a death happened.
  • Monday's bioethics debate connects here: who should be allowed to decide that an is performed, and does the family get a say?
  • Your graded evidence table is submitted on the class site.
Do the work

Do this: Advance the PLTW PBS Unit 1.2 benchmark by analyzing microscopy and toxicology evidence in the online course shell.

Know when done
  • is the body's maintenance of stable internal conditions across organ systems.
  • is the microscopic study of tissues, which differ by structure and function.
  • Toxicology evidence compares measured levels against a .
Be able to do
  • Identify types using a microscope.
  • Interpret toxicology results relative to a .

What to do when absent

If YOU are absent

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 myPLTW

Sign 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.

Was today a lab or a group activity?

You can't do those from home: do this instead: Teacher-posted data/model packet, same objective. Supplemental: Khan: human body systems; visible body/ references if district approved.

If MR. MENDOZA is absent

Class still runs. A substitute will post today's plan: complete the online activity above; it's built to be self-guided. Need the concept taught without a teacher? Use this authoritative explainer:
