Today we are learning

I can deliver my defense in the format I chose, answer at least one panelist question, and name one thing about my AI use I would change next time.

What today is about

First defense of the year. The room is on your side.

Due at the start of this block: Dossier + AI Documentation

Dossier and AI Documentation due at the start of this block, in Google Classroom. Defenses run for the rest of the period. Submit to "S - Unit 0 Source Dossier", which stays open until Tuesday 1 September. Use the Dossier Assembly Checklist as your cover sheet: it is in Classroom.

Submit via Google Classroom (link posted in August)

Today is the first of the eight defenses you'll give across the year. 5-minute pitch + 2-minute Q&A; 8–10 students defend live; the rest submit the written essay defense, which Ms. Jayanthi/Mr. Ignash reviews after class. The point isn't perfection; it's the rep, one practice round of many. Seven more defenses follow this one. Use today to learn what you sound like under questioning.

The unit closes with a reflection on what you learned about how you think (not what you learned about contested topics) and a preview of Unit 1. Unit 1 will use the OPVL muscle you just built: same framework, applied to planetary science sources.

Before you start the work

Start with the Watch: projected at the start for everyone. The Read is there if you want to settle nerves before going up.

Watch (~3 min)
There is no sample from a previous class: you are the first group to do this. What we film this year (with your permission) becomes next year's example.
Read (~5 min)
The Rubric: quick-reference for the C strand (Communication). Defenses are scored against the rubric's clarity + responsiveness criteria.

Today's work: the defenses themselves

No choice board today. The block runs on a roster: 8–10 students defend live; everyone else either delivers in alt format (asynchronous review) or sits as panelist-observer for at least one live defense.

Learning Intention: I can deliver my defense in the format I chose, answer at least one panelist question, and name one thing about my AI use I would change next time.
A
Live defense (5-min pitch + 2-min Q&A)
You're on the roster for today. Set up, deliver, answer questions. Panelists are 2-3 peers + Ms. Jayanthi/Mr. Ignash. Stay on the panel after for at least one other student's defense.
Solo · Live
B
Panelist-observer
If you're not delivering live today, sit as a panelist for at least one defense. Use the observation guide to give the speaker specific, rubric-aligned feedback. This counts as participation.

C
Written defense finalization
If you are submitting the written essay defense, today is the day to finalize it. Read it aloud once to yourself before you submit: the five parts were built to be spoken, and anything you stumble over reading is usually a sentence worth rewriting. Quiet corner is available.

Open your Class Notebook and type today's entry header as Heading 2:

What you're submitting today

Two things, on top of the dossier that came in at the start of the block: the defense itself and a one-paragraph AI Doc reflection.

Defense delivered + AI Doc reflection paragraph

The defense (live recording or written response) is captured by end of class. The AI Doc reflection (one paragraph: "what would I do differently next time I use AI on a dossier-scale task?") gets appended to your dossier.

Submit via Google Classroom (link posted in August)

Rubric link: Today is the C strand score for the Source Dossier: clarity + responsiveness under questioning. See the rubric.

One question before you leave

Three to five minutes. Your answer is saved to your reflection journal, where you can read back everything you have written this year.

Unit-close reflection. This one matters: it's about how YOU think, not about the topic.

Today's reflection is in Google Classroom, under Reflection Journal.

Where we go next

Unit 1 asks: what makes a planet habitable? Same OPVL muscle, applied to planetary-science sources (NASA data, exoplanet detection papers, atmospheric chemistry textbook chapters). You'll write the Goldilocks Report and defend your habitability framework against a NASA-committee panel. Same defense format you just survived, just with a new topic and slightly more technical sources.

The framework you built this unit (OPVL + AI Documentation Protocol) doesn't get retaught. It gets used. Lovelock (1965) (the life-detection paper you OPVL'd in Blocks 2 + 3) is also still relevant: U1 Block 1 picks it up again as the bridge into habitability work, because "how would we recognize life elsewhere?" is the same question as "what makes a planet habitable?" If something feels shaky from Unit 0, the Foundations pages stay live all year.
