Week overview - Forensics and Final Portfolio: chain of custody, claims, and the audit

Apr 27–May 3

Apply chain-of-custody basics, sharpen your independent research question and methods, and audit your final portfolio against the checklist.

Week arc
  1. 1In your notebook, write the chain-of-custody steps that keep evidence trustworthy from collection to court.
  2. 2State your independent research question in one clear, testable sentence.
  3. 3List the methods you will use and one limitation each method carries.
  4. 4Write one claim from your project and the evidence that supports it.
  5. 5Open the portfolio checklist and mark each required piece as done or missing.
  6. 6Make a short to-do list of the missing pieces and pick the first one to finish.
By week end
  • You will be able to explain why chain of custody protects evidence integrity.
  • You will be able to state a testable research question with methods and limitations.
  • You will be able to audit a portfolio against required criteria.

Get oriented

Quick intro to the week

  • Hook: whether in a courtroom or a research portfolio, evidence is only as strong as the record that tracks it.
  • Today's goal: tighten your project claim and confirm your portfolio is complete.
  • Monday bioethics debate closes the year: what does honest research owe to the people it studies?
  • Reminder: your graded portfolio audit is submitted in the PLTW course shell.
Do the work

Your PLTW coursework this week

Do this: Advance your PLTW independent project by completing your research-question refinement and final portfolio audit in the online course shell.

Know when done
  • Chain of custody documents who handled evidence and when to protect its integrity.
  • A strong claim is backed by evidence and names its limitations.
Be able to do
  • Write a testable research question with methods and limitations.
  • Audit a portfolio against required criteria.

📋 PLTW evidence due: a refined research question with methods and limitations, plus a completed final portfolio audit in the course shell.

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

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 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.

Was today a lab or a group activity?

You can't do those from home — do this instead: Portfolio checklist.

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:
