I-95 BRIDGE EXPANSION — TEACHER QUICK GUIDE
MeMe JJ & Friends • Career-Infused Learning (CIL)
Grades 6–8 | Free simulation | Facilitator reference

GOAL
Students make evidence-based decisions inside four connected professions, rather than learning school subjects apart from the work in which those subjects are used.

STATION SEQUENCE
1. Surveyor — record at least three observations and calculate proposed additional deck width.
2. Civil Engineer — calculate width increase and percentage; select the responsible structural-testing recommendation; write a missing-evidence handoff note.
3. Architect — manipulate the proposed support position, compare Option A and B, calculate a drawing-scale conversion, and justify constraints in writing.
4. Software Developer — detect a flawed sample analysis export, reconcile the illustrative equipment reaction, and explain why the engineer needs revalidation.
5. Project portfolio — select the evidence-based recommendation, write the final cross-profession reflection, and download the student record.

FACILITATOR CHECKPOINTS / EXPECTED VALUES
• Surveyor: existing deck 48 ft, proposed deck 72 ft, additional width 24 ft. At least 3 observation buttons must be recorded.
• Civil Engineer: 24-ft increase; 50% of the original 48-ft width. Responsible decision: request structural load and support testing before approval. Students must write a structural evidence question.
• Architect: 40 ft at 1 inch = 10 ft converts to 4 inches on the drawing. Option A / B are evaluated for tradeoffs rather than certified. Writing rubric looks for dimensions, evidence, comparison, constraints, and sufficient explanation; teacher judgment is required.
• Software Developer: deliberately inconsistent example shows construction equipment input 260 kN vs reaction 26 kN, and reported reaction sum 626 kN vs input total 860 kN. Correct the classroom consistency check to 260 kN, explain mapping/units checks and need for a fresh, verified engineering export.
• Final: continue coordinated review; no construction approval. Final reflection requires 35+ characters connecting professional evidence.

USE IN CLASS
• Allow one device/browser per student or pair.
• Have learners explain why field measurements are necessary but insufficient for structural approval.
• Ask who must receive which evidence, and what each profession is NOT authorized to certify.
• Use Download student portfolio (.txt) or Print project record for assessment; each learner's answers appear in the portfolio.
• Progress is stored locally if browser settings permit. Restart simulation clears recorded progress on that browser.

IMPORTANT SCOPE
Simplified fictional values and a deliberately invalid software export illustrate professional habits of verification. This is not true CATIA output, a full paid engineering lab, a structural report, professional engineering software, or AI coaching. No actual I-95 bridge or structure is assessed. Teacher review is necessary for written reasoning.
