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 touch, mouse, or Tab and Enter. Fieldwork uses evidence and comparisons; Switchyard uses loading and routing; Connections uses swaps and flips; Model Works uses part exchanges or an experimental timeline. Dragging is optional. Puzzle moves and shipping efficiency are separate from concept accuracy.
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 per stage for play and feedback, plus about five minutes across the written checkpoints. Adjust the pace to your students; there is no countdown or speed penalty.

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.
