OBSERVE: Pull down slowly on the stretched balloon. What happens to the balloon inside the cup? The balloon inside fills with air and gets bigger

Push up on the stretched balloon. What happens inside the cup? The little balloon inside of the cup deflates.

EVALUATE: Is there more or less space inside the cup when you pull down on the large balloon? There is more space inside of the cup when you pull down the large balloon.

IDENTIFY: When you pull the large balloon down, what fills the extra space in the cup? The cups empty space is filled by the little balloon inflaiting

COMPARE: How is the air pressure in the balloon similar to the air pressure in your lungs? Write down what you think happens when you breathe air into your lungs. When you inhale you your lung fills with air like the little balloon in side of the cup it fills with air.

Good job, Nick. You made good observations. I would encourage you to think further about what is really filling the empty space in the cup when you pull the large balloon down. What made the little balloon inflate? You forgot to answer the questions about how the air pressure in the balloon is similar to that of your lungs. Mrs. Escue
