Holiday Ornament Buoyancy Density STEM Lab (XMAS04) | Middle School Christmas Physics

? Holiday Ornament Buoyancy Density STEM Lab (XMAS04)

Explore Archimedes' principle, fluid displacement, average density calculations, buoyant force vs. gravity, neutral buoyancy equilibrium, and ballast engineering! The Holiday Ornament Buoyancy Density STEM Lab (XMAS04) challenges middle school student teams to act as North Pole materials engineers, fine-tuning ornament mass and volume to suspend floating displays at precise water depths.

Students explore density physics, Archimedes' displacement, neutral buoyancy state balance, and mass-to-volume ratio math!
