Parts of a Submarine for a 3-year-old — Simple Kid-Friendly Guide

Hello! A submarine is a big, boat-like vehicle that can go under the water. Here are its parts:

• Hull (body) — The big, strong body that keeps water out.
• Sail (top) — The little tower on top where people look out.
• Periscope — A long eye that pops up to see above the water.
• Propeller (back fan) — The spinning fan at the back that pushes the submarine along.
• Rudder and fins — Tail pieces that help it turn and move up or down.
• Ballast tanks — Tanks that fill with water to sink and empty to float.
• Hatch (door) — The door where people get in and out.
• Control room — The place where people steer and watch the instruments.
• Engine (motor) — The thing that makes the submarine move.
• Sonar (listening ear) — Like an ear that listens under the water to know what is around.

That's it! A submarine is like a secret underwater house that can swim. Would you like a simple picture to look at next?
