The Skeletal System

Our skeleton is like a skyscraper

Imagine a giant skyscraper reaching up into the sky. Up at the very top there are hundreds of workers busy doing their jobs. No matter what the weather is like outside, these workers feel safe, because they know that the building was built very strong. Even on windy days, the building will not fall over.


The framework of a building provides it with strength

What gives buildings their super strength? The secret is in their bones. Well, sort of.Buildings are built around a steel framework. This framework holds the weight and allows the builders to go as high as they want.

Your body is similar to a skyscraper. A small ant might look up at you and think “wow, what keeps that large animal from falling over?” The secret to your strength lies in your bones.


Just like a skyscraper, your body is built around a hard and strong framework. Instead of steel and concrete, your bones are made out of very hard materials that we will explore later.

In a building, workers use nails, bolts, glue and concrete to hold the building to the framework. Your body has similar materials, such as ligaments and muscles, which hold everything together.
