The Design Gateway (Indiana NGSS MS-ETS1)
GATE-CODE: [ _ _ _ _ ]
Match each intercepted engineer field action to its official Design Process Step Number. The sequence of numbers from Log Alpha to Log Delta reveals your 4-digit access code.
The 6-Step Engineering Design Process:
1: Define a problem 2: Generate concepts 3: Design a solution 4: Build & Test 5: Evaluate solution 6: Present solution
LOG ALPHA (MS-ETS1-1):
"Our team surveyed school users, established budget limits ($35) and size limitations (200mm cube), and formulated our formal criteria and constraints."
Step #
LOG BRAVO (MS-ETS1-2):
"We held an open brainstorming session, sketched 15 thumbnail concepts, and ranked them on a decision matrix to pick our top competing approach."
Step #
LOG CHARLIE (MS-ETS1-4):
"We fabricated a working 3D-printed physical scale model and conducted load-bearing drop tests to collect empirical performance data."
Step #
LOG DELTA (MS-ETS1-3):
"We analyzed our drop test data graphs against our criteria, identified structural weak points, and determined necessary design revisions."

5-DIRECTION LOCK
To recalibrate the 3D optical cameras on your Chromebook, reconstruct the flight path around a prototype assembly using standard Tinkercad Navigation & Chromebook Gestures. Follow the vector trail and decode the 5-step directional combination (▲ UP, ▼ DOWN, ◄ LEFT, ► RIGHT).
ViewCube & Home Click faces/edges to snap views. Click Home (house) to return to default angle.
Chromebook Orbit & Pan Orbit: Alt + Click-drag (or two-finger tap-drag).
Pan: Shift + two-finger drag.
Zoom & Focus Key 'F' Two-finger scroll zooms in/out.
Press F to Fit/Focus camera directly on selection!
Vector Path Analysis (Read each maneuver carefully)
RECORD ARROW DIRECTION
NAV-1: You are currently looking at the FRONT face of the ViewCube. You click the top face arrow on the ViewCube to inspect the mounting screw holes from directly above.
Direction
NAV-2: From the front view, you need to view the right side motor housing. To pivot camera perspective toward the right face, the camera orbit rotates:
Direction
NAV-3: The assembly model drifted far off-screen. On your Chromebook, you hold Shift and drag two fingers downward along the trackpad to pan the view back down to the center.
Direction
NAV-4: From the Right side view, you want to inspect the Front face again. You click the rotational arrow on the ViewCube directing back toward the front:
Direction
NAV-5: To inspect the underside battery compartment below the workplane grid, the camera tilts directly downward to expose the BOTTOM face.
Direction
Directional Cipher Validation Rule: Use symbols: [ ▲ UP, ► RIGHT, ▼ DOWN, ◄ LEFT ]
Transfer the 5 arrow directions in order (NAV-1 through NAV-5) to input your Lock 2 directional security sequence.

Subsystem 03 CHROMEBOOK CAD COMPILER
LOCK 03: THE SHORTCUT MATRIX
5-LETTER WORD LOCK
The modeling engine's keystroke compiler has locked down all hotkeys. Below are 5 modeling operations essential to rapid CAD prototyping on Chromebooks. Match each operation with its exact Tinkercad Shortcut. Then, locate the assigned cipher letter for each correct key combination to spell out the 5-letter clearance word.
Chromebook CAD Hotkey Cipher Table MATCH SHORTCUT TO CIPHER LETTER
Ctrl + D Smart Duplicate Letter 'B'
Ctrl + G Group Shapes Letter 'U'
Key 'L' Align Tool Letter 'I'
Key 'W' Workplane Tool Letter 'L'
Key 'R' Ruler Tool Letter 'D'
Key 'D' Drop to Plane Letter 'M'
Ctrl+Shift+G Ungroup Letter 'P'
Key 'M' Mirror / Flip Letter 'T'
OPER-1:
You need to clone a gear tooth in place and repeat the rotation angle around a center axle without manually pasting each time.
Shortcut Ctrl + D
OPER-2:
You positioned a cylinder designated as a "Hole" inside a solid chassis block. You must fuse both shapes so the hole subtracts an opening.
Shortcut Ctrl + G
OPER-3:
Two robotic arm links are offset. You select both parts and press this single key to activate black alignment nodes to center them on the same axis.
Shortcut Key 'L'
OPER-4:
You need to place a sensor directly on an angled roof face. You press this key to snap a temporary building grid directly onto that slanted surface.
Shortcut Key 'W'
OPER-5:
To measure the exact distance between hole centers and ensure parts meet size constraints, you press this key to drop the measuring datum ruler.
Shortcut Key 'R'

6-LETTER OVERRIDE
The 3D printer queue halted because a prototype assembly failed validation. Connect the Engineering Design & Evaluation cycle with Tinkercad geometry troubleshooting to deduce the Master 6-Letter Override Keyword.
Prototype Failure Incident Report #91 STATUS: FAILED INSPECTION
"The mechanical latch prototype was 3D printed, but bound up and broke during testing. An evaluation showed: (1) Pivot pin was 0.5 mm too wide because clearance wasn't verified with the Ruler (R); (2) Holes were misaligned because Align (L) was omitted; (3) The team must now enter the design stage of revising and optimizing."

STATION 1 ANCHOR MS-ETS1 PROTOCOL
The 6-Step Engineering Loop
Keep this reference active at Station 1. Notice the subtle distinctions between early problem scoping and middle-stage prototype verification.
1. Define a problem (MS-ETS1-1)
Design brief, criteria (goals), constraints (limits: cost, time, size).
2. Generate concepts (MS-ETS1-2)
Brainstorming, thumbnail sketches, decision matrix to select best idea.
3. Design a solution
Detailed 3D CAD modeling in Tinkercad, technical drawings, precise dimensions.
4. Build & Test (MS-ETS1-4)
Working scale prototype, 3D printing, physical stress tests, data logs.
5. Evaluate solution (MS-ETS1-3)
Data analysis against criteria; recommendations for redesign & optimization.
6. Present solution
Formal showcase, documentation portfolio, project debrief & pitch.

HINT TOKEN 01 CONFIDENTIAL
Station 1 Scaffolding Cards
Fold or hand to teams only when they have spent 5+ minutes stuck on Lock 01.
Level 1 Hint:
Log Alpha explicitly mentions "criteria and constraints." That is always the very first step (Step 1: Define a problem).
Level 2 Hint:
Log Bravo uses a "decision matrix" to select among brainstormed concepts (Step 2). Log Charlie talks about physical test data (Step 4: Build & Test).
Level 3 Hint:
Log Delta involves evaluating drop test data against criteria to recommend revisions (Step 5). The four steps are in chronological order: 1, 2, 4, 5!
