Egg
This is the day I was laid:

Eating
You may wonder where i take my nutrients from...
This is how it looks inside here!
My egg contains albumen or “egg white” and a yolk. I develop within the yolk and feed off of it and the white. Inside here I have shelter, food, almost everything i need... except, it seems, a little fresh air.
You may wonder how I can breathe inside this egg... but if we zoom in the egg shell under the microscope you will find an interesting surprise...
Breathing
Pores on the egg’s shell!

Zoom
Pores on the surface of the egg shell not only allow for gas exchange but also for the exchange of water between the embryo and the environment.
So now you know how i get my nutrients and the oxygen i need to grow...another very important variable is the temperature. I need to be kept warm in order to survive... I can’t control my body temperature when I’m inside here so i need to be incubated.
Incubation
Did you know?
When a material can’t isolate the heat,
We call it a heat conductor?
When a material can’t isolate the heat,
We call it a heat conductor?
How can we tell if a material is a good insulator?
Thermal insulators are bad at transferring heat. Materials can transfer heat when molecules that had absorbed heat(energy) bump into colder molecules.
My mother and my father will carefully select the nest materials. These materials should be good insulators to prevent the heat from escaping!
There’s a property of the material that tells us how good the material can transfer/conduct heat. It’s called the thermal conductivity.
Big thermal conductivity
Material is good thermal conductor
Small thermal conductivity
Material is good thermal insulator
Thermal conductivity of some insulators
Thermal conductivity of some metals
So...although my parents never learned about thermal conductivity, if you observe the materials from which my nest is built, you will soon discover that a lot of insulating materials were picked...
