A lighthouse is like a giant flashlight on top of a cliff or island. When it shines, ships can see it from far away and know where to go. The light moves in circles or flashes so sailors can tell how far away the lighthouse is, just like when you wave your hand in front of a light and it makes shadows that move.
Examples
- A child playing with a flashlight at night can see it from across the room, just like how sailors see a lighthouse from far out at sea.
- When you turn on a spinning disco ball, the lights move around the room in patterns, this is similar to how some lighthouses flash light in rhythmic patterns.
- A dog running on a beach uses landmarks to find its way home, a sailor uses a lighthouse as their landmark at sea.
