lung+investigation

OBSERVE: Pull down slowly on the stretched balloon. What happens to the balloon inside the cup? __The balloon got puffed up and air went in it so it could do it.__ Kyle, which balloon puffed up? Push up on the stretched balloon. What happens inside the cup? It deflates complety so there is no air What deflates?

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

IDENTIFY: When you pull the large balloon down, what fills the extra space in the cup? Air in the cup and air goes in the balloon because there is more room. Where did the air come from?

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. i think it's similar because when there is more room in the lungs they fill up with air. What is your response to the second part of this (what you think happens...).

Kyle, I would encourage you to take more time and really think about the question and the answer prior to submitting your final responses. You're on the right track but need to be more clear. You're smart enough to do this! Mrs. Escue
