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 works.
- 1Open your design notebook and write the one problem your 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 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 test.
Open any day for its full lesson, the work due that day, and guided notes.
Validation plan with 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.
Culturing record: your coded sample letter, the dilution scheme (1/10, 1/100 and 1/1,000), the volume plated (0.1 mL), the label on every plate, a completed sterile-technique checklist, your prediction of which dilution will give 30 to 300 colonies with the arithmetic behind it, and both controls named. Results stay pending until the plates are read on April 9.
Mitigation notes with a plate-count record (colonies on your 30 to 300 plate or the C2 practice data, per mL with the calculation shown, and one sentence on why LB growth is not a coliform test), 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 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 .

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.
