Learning Goals
Students will be able to model particle motion, spacing, and energy in scuba tanks and underwater gear to explain how heating and cooling change pressure and volume.
Students will be able to calculate scuba air needs using pressure, temperature, volume, and quantity relationships to plan a safe dive.
Students will be able to estimate heat loss and warming-device effectiveness using simple calorimetric calculations and energy conservation.
Students will be able to develop and revise a low-tech warming-device prototype for a diver based on test data and feedback.
Students will be able to communicate an evidence-based dive safety briefing that justifies air-supply and warming decisions with calculations, models, and test results.
Products
Individual Dive Air-and-Warmth Research Brief with Testable Prototype Sketch
Each student creates a research brief that uses firsthand evidence from stations, calculations, and models to explain air needs and heat loss for a short scuba mission. The brief also includes a labeled low-tech prototype sketch for a diver-warming device and a short rationale tied to user safety.
Coast Guard Dive Safety Board and Tested Warming-Device Prototype
Teams produce a shared dive safety board with a route map, checklist, air calculations, particle models, and a collaboratively refined warming-device prototype. They present it to an authentic audience and explain how user feedback and science evidence shaped the final design.
