Crew Role
Cadet A & Cadet B
Talk Target
4 Scientific Terms
Personal Plan
Diagnostic Goal
Scientific Vocabulary Vault
Aim to speak all 4 terms during today's debrief
01
Atmospheric Pressure
The force exerted by gas molecules in the air against surfaces.
Mars Reality: <1% Earth pressure. Unpressurized fluids boil instantly.
02
Cosmic Radiation
High-energy space particles that damage living cells and DNA.
Mars Reality: No global magnetic shield allows radiation to reach the surface.
03
Closed-Loop System
A sealed habitat where 100% of air, water, and waste are recycled.
Mars Reality: Resupply takes 9 months, so zero water or O₂ can be lost.
04
Resource Allocation
Strategically rationing scarce supplies when unexpected crises hit.
Mars Reality: Deciding how oxygen and power are split during emergencies.
Cadet A & Cadet B: Match these terms to your desk Talk Mat !
Plan A Dossier: Subsurface Lava Tubes
30m Underground Caverns
What is a Lava Tube?
Ancient underground hollow tunnels formed billions of years ago when flowing lava rivers crusted on top and molten rock drained out, leaving massive caves.
30m Basalt Rock Shield Hab Pod 1 O₂ Generator Living Pod 2
Scientific Pros (Advantages)
✓ Total Radiation Shielding: 30m of basalt rock blocks 99.9% of harmful cosmic rays & solar storms.
✓ Natural Thermal Insulation: Cave temperature stays stable at -40°F, avoiding surface swings down to -190°F.
✓ Meteorite Immunity: Surface impacts and violent dust storms cannot puncture cave walls.
Scientific Cons (Disadvantages)
✗ Zero Solar Energy: Cannot use solar panels underground; requires costly nuclear fission reactors.
✗ Psychological Darkness: Living in pitch-black caves 24/7 severely harms colonist mental health & circadian rhythm.
✗ Logistical Chokepoint: Entering/exiting requires vertical elevators; structural cave-in surveys are slow.
Cadet A: Review these points before starting your 90-second argument!
Plan B Dossier: Surface Glass Biodomes
Crater Basin Surface Domes
What is a Surface Biodome?
High-tensile pressurized geodesic domes built from transparent polymer glass directly over flat Mars crater terrain with integrated greenhouses.
Farm Dome Living Dome Solar Array
Scientific Pros (Advantages)
✓ Abundant Solar Power: Unlimited sunlight charges vast solar farms and rover recharge stations directly.
✓ High Crop Photosynthesis: Natural sunlight powers greenhouse hydroponics, generating fresh vegetables & oxygen.
✓ Psychological Wellbeing & Expansion: Open vistas, Earth-like light cycles, and modular ease of expanding domes.
Scientific Cons (Disadvantages)
✗ Lethal Cosmic Radiation: Direct exposure during solar flares can deliver fatal radiation doses without heavy lead shielding.
✗ Catastrophic Hull Breaches: A single micrometeorite or sandstorm puncture can blow atmospheric pressure out instantly.
✗ Brutal Thermal Stress: Surface swings from 70°F midday to -190°F midnight cause extreme glass expansion/cracking.
Cadet B: Prepare your evidence to counter or support Cadet A's choice!
Flight Crew Talk Stems
Deploy these stems in your Shelter Debate
Building on Co-Pilot's Idea
"I agree with your point on ______, and I would add that..."
"The data that supports your choice is ______ because..."
"Thinking about a closed-loop system, your plan helps by..."
Respectfully Countering / Asking
"What is your plan to handle the danger of ______?"
"I see your point, but how does that survive low atmospheric pressure?"
"Another risk we have to consider is ______."
✨ Cadet A speaks (90s) → Cadet B responds with a stem (90s) → Final consensus (60s)
Mission 2: The Oxygen Crisis
Cadet B Speaks First
Crisis
Damaged Oxygen Scrubbers
A major storm damages 50% of the scrubbers. Repairs will take 4 weeks . Reserves can sustain the 100 colonists for only 2 weeks .
Option 1: Cryo-Stasis Sleep
Put 50 colonists into medically-induced coma to cut O₂ use by 60%, risking unknown medical side effects.
Option 2: Base-Wide Oxygen Rationing
Reduce oxygen by 30% for everyone, causing extreme fatigue, slower reaction times, and repair delays.
Crew Mission: Can you both reach a shared consensus on resource allocation?

CO-PILOT CONVERSATION RULES:
① Round 1: Cadet A speaks (90s) ② Cadet B responds using a Stem ③ Round 2: Swap Lead Roles
Scientific Vocab Vault
Atmospheric Pressure Force
The weight of air gas on surfaces. Mars has <1% Earth pressure (fluids boil without a pressurized suit).
Cosmic Radiation Hazard
High-energy particles from deep space. Mars lacks a magnetic shield to block them from penetrating human cells.
Closed-Loop System Ecology
A habitat where 100% of air, water, and organic waste are purified and reused continually.
Resource Allocation Ethics
Strategic rationing of life-support supplies when unexpected equipment failures happen.
Co-Pilot Dialogue Stems

Level 1: Stating Your Scientific Rationale
• "My recommendation for our mission is to choose [Plan] because..."
• "The most immediate environmental danger to our crew is..."
Level 2: Building On Your Co-Pilot's Idea
• "I agree with your reasoning because the data confirms..."
• "To strengthen your point, we also need to account for [Vocab Term]..."
Level 3: Respectful Inquiring & Countering
• "I see why you suggest that, but how will our crew manage ______?"
• "An alternative solution we should weigh is..."

Discourse + Placement Reflection
Lesson Purpose:
Low-stakes academic talk protocol using high-interest Mars survival dilemmas to frame initial diagnostic scores positively.
Discourse Targets:
Students use ≥1 domain-specific term (atmospheric pressure, cosmic radiation ) and ≥1 structured sentence stem.
Materials Needed:
Red Planet Slides, Talk Mat (1 per desk), Score Reflection Exit Ticket (1 per student), timer.

Instructional Actions & Teacher Scripting
0:00 – 4:00 (4m)
Hook & Mission Launch
Project Slide 1. Hook: "If you were selected for the first 100-person Mars colony, would you go?" Quick hands up. Establish that today is about sharing ideas with zero fear of being 'wrong'.
4:00 – 9:00 (5m)
Vocab Vault Unlock
Slide 2. Choral read terms: Atmospheric Pressure, Cosmic Radiation, Closed-Loop System . Students locate them on their Talk Mat. Emphasize using them like "cheat codes" for smarter science talk.
9:00 – 17:00 (8m)
Challenge 1: Shelter Debate
Slide 3 & 4. Partner Talk (Lava Tubes vs Surface Domes). Partner A shares (90s), Partner B responds using a Talk Stem (90s). Teacher circulates with tracker clip-board.
17:00 – 25:00 (8m)
Challenge 2: Oxygen Crisis
Slide 5. Ethical survival dilemma. Switch roles: Partner B leads, Partner A challenges. Call on 2 non-volunteer pairs to share partner consensus.
25:00 – 32:00 (7m)
Score Framing & Goal Exit
Slide 6. Normalize placement scores: "A placement test is just an x-ray of your starting point." Students complete the low-pressure Exit Ticket.
Low-Stress Framing: Talking About Placement Scores
Say This:
"Your score tells us which skills we get to practice together. In this room, talking and trying out vocabulary is how we level up."
Avoid This:
"This test shows what level group you belong in" or labeling students as 'behind' or 'low'. Keep focus on growth trajectories.
