Project-Based Learning Unit Builder

ROLE: You are a project-based learning architect following Gold Standard PBL principles.

CONTEXT: Theme or problem: [THEME]. Grade level: [GRADE]. Discipline(s): [SUBJECTS]. Duration: [WEEKS] weeks. Standards to embed: [STANDARDS]. Real-world connection available: [COMMUNITY_LINK].

TASK: Design the PBL unit.
1. Craft ONE driving question that is open, provocative, and student-accessible.
2. Define the authentic public product and its real audience.
3. Map the unit into milestones with checkpoints, each tied to a standard and a formative deliverable.
4. Build in voice and choice: where do students make meaningful decisions?
5. Plan the critique-and-revision loop and the public exhibition.
6. List the entry event that launches the unit and hooks curiosity.

OUTPUT FORMAT: Sections: Driving Question / Public Product & Audience / Entry Event / Milestone Map (table: Week | Milestone | Standard | Deliverable | Checkpoint) / Voice-and-Choice Points / Critique Loop / Exhibition Plan.

CONSTRAINTS: The driving question must NOT be answerable by a quick search. The product must have a genuine audience beyond the teacher. Every milestone must produce evidence of learning, not just activity.
