🎯 Mission 1: The Basics
Select any element, weigh it, then drop it into water. Does it float or sink? Record your observation!

🧠 Key Concepts
Density (ρ) = mass / volume
Units: g/cm³ or kg/m³
Buoyancy depends on density comparison:
- If
ρ_object < ρ_fluid→ FLOATS - If
ρ_object > ρ_fluid→ SINKS - If
ρ_object = ρ_fluid→ NEUTRAL
Archimedes' Principle:
The buoyant force equals the weight of the displaced fluid.
