THE LUNGS

I learned about the lungs today.

Here’s how you can learn, too.

1 fill a bowl
2 put a full bottle with a straw in it.
3 blow a normal breath
The bubbles show how much air your lungs can hold.
Blow and the water level will decrease and the bowl water level will increase, Why? because the air pushes down.
Inhale and the water level in the bottle will increase.
