Why Do Huge Ships Float?
Ages 3–9
Key Insight
Ships float because they push away a lot of water, and the water pushes back up!🚢
📖 Explanation
🧒 For Ages 3-5 (Simple Words)
Even though big ships are heavy, they are full of air like a balloon! The water pushes the ship up and keeps it safe on the surface.🌊
🎒 For Ages 6-9 (Science Talk)
Archimedes' Principle
An object floats when it displaces an amount of water equal to its own weight. Because ships are hollow and wide, they push away a lot of water, creating enough upward force (buoyancy) to stay afloat.
