What to do if absent- CER:
- Claim, Evidence, Reasoning: make a claim, back it with evidence, explain your reasoning.
- SOP:
- Standard Operating Procedure, the exact steps to follow (especially in a lab).
- Tracker:
- Your PLTW progress log where you record completed evidence.
- myPLTW:
- The PLTW course site where you do the online activities. Find it in Clever with your Microsoft sign-in, right next to Schoology.
Week overview - Validating Your Prototype: literature review, decision matrices, and metrics
Run a focused , build a to choose a design, and define the metrics you will use to prove your prototype works.
- 1Open your design notebook and write the one problem your prototype is meant to solve in a single sentence.
- 2Find three credible sources on your topic and write one fact from each, noting whether the source was peer reviewed.
- 3Build a with your top design options as rows and your criteria as columns, then score each cell 1 to 5.
- 4Circle the option with the highest total and write one sentence on why the matrix supports that choice.
- 5List two measurable validation metrics (a number you can record) that would show your prototype is working.
- 6Draft a simple : what you will measure, how many trials, and what result would count as success.
- • You will be able to summarize credible sources and tell peer-reviewed work from opinion.
- • You will be able to use a to justify a design choice.
- • You will be able to define measurable validation metrics for a prototype test.
Open any day for its full lesson, the work due that day, and guided notes.
Validation plan with prototype claim, two measurable metrics with units and pass/fail thresholds, a control, a test procedure, and one error-reduction step.
One-sentence evidence-based statement on who bears responsibility for unequal pollutant exposure and why.
Detection-limit : the claim you predicted, the concentration of every tube in the series, the color call for each, the positive and results named as such, the detection limit stated with units, the coded unknown result, one sentence comparing your detection limit to the assigned EPA drinking-water limit, and one named limitation of reading this test by eye.
Mitigation notes with two strategies (source-side and -side), dose-reduction predictions, feasibility tradeoffs, and a justified recommendation.
- Hook: real innovators do not guess whether their idea works, they measure it, and this week you learn how.
- Today's goal: turn a pile of ideas into one defensible design with a behind it.
- Monday bioethics debate ties in: is it ethical to cite a source you never actually read?
- Reminder: your graded and validation plan are submitted on the class site.
Do this: Advance your PLTW innovation benchmark by completing the and for your prototype in the online course shell.
- • A gathers and summarizes credible prior work before you design.
- • A scores options against weighted criteria to support a choice.
- • Distinguish peer-reviewed evidence from unreviewed claims.
- • Define measurable validation metrics for a prototype.

Fiction. There is no such student. The lessons, labs and dates are the real planned course; the student, the classmates and the conversations are invented.
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.
