1. Use after introducing the topic, or pause to explain unfamiliar ideas during play. These activities do not replace the course instruction.
2. Have students read the feedback and give a reason for a move. Correcting a mistake is part of the work.
3. Use the keyboard or on-screen controls to move. Clicking a person also walks the character to the conversation. Three leads and a main challenge lead to each new chapter.
4. Review the written checkpoints. The game checks that a note is present; it does not automatically grade the student’s reasoning.
5. Download a save for shared devices or another browser. Keep names and personal health details out of the notes.

Suggested play time: Allow about five minutes to enter the world, 10–15 minutes per chapter for exploring, testing, and writing, and another 10 minutes to compare explanations. This gives a 55–75 minute starting estimate; readers and discussion groups may need longer.

Model limits: An original fictional learning world. All characters, local events, numerical results, budgets, and point changes are simulated. The map is schematic. This activity practices selected College Board topic objectives and science practices; it is not an official College Board product, a clinical assessment, or evidence of mastery by itself. Allow 60–90 minutes including reading, revision, and written reflection; classroom duration has not been piloted.
