What is an egg made of, from the yolk to the shell?
An egg is a complete packed lunch for a growing chick. The yolk is full of fat and protein for food. The clear, thick white around it holds water and cushions the yolk. Thin skins called membranes lie inside the hard shell, which is made mostly of calcium. The shell protects everything and lets air in. Together, the parts give a chick everything it needs to grow.

The Big Idea
An egg is a packed lunch for a chick! Every part has a job. What is an egg made of?
The Yolk
Step one: The Yolk. The yolk is full of fat and protein. It is food for the growing chick.
The White
Step two: The White. The clear, thick white around the yolk holds water. It also cushions the yolk, like a soft pillow.
Membranes and Shell
Step three: Membranes and Shell. Thin skins called membranes lie inside the hard shell. The shell is made mostly of calcium. It protects everything and lets air in.
A Closer Look
Let's take a closer look! Food. Water and cushion. Thin skins. Mostly calcium.
Quick Facts
Quick facts! A bird egg is a tiny life-support system. Eggshells are mostly calcium. Yolks are full of fat and protein. Shells let air in.
Think Like a Scientist
Now, think like a scientist! With a grown-up, crack a raw egg into a clear bowl. Find the yolk. Find the clear white and the thin skin inside the shell. Don't taste the raw egg. Wash your hands with soap afterward.
