Agent-based model of desk water bottle policies vs. hall pass disruptions across 45-minute lesson blocks.
Current Policy: Desk Bottle Permitted (Covered Caps)
Instructional Impact: Low out-of-class movement, minimal micro-distractions caused by bottle cap unscrewing and minor drops.
Recommendation: Covered cap policy preserves 18.5 lost instructional minutes per week compared to 42.0 minutes under Hall Pass routines, maintaining 92.5% hydration compliance.
