Thinking About The Question
How do you inhale and exhale with your lungs?
How can you inhale and exhale with your lungs?
To investigate this question, you are going to use a model.
Have you every made a paper airplane or played with a toy car or doll? These are models, which in some way resemble their real counterparts. Have you ever used a flight simulator? Again, this is a model made to help people learn how to fly an aircraft. Often scientists make models, picking and choosing what aspects are most important to include in the model.
Look at the paper airplane below. How does this model resemble or behave like the real thing?
How does it differ from a real airplane?
Look at the list below and indicate whether or not the item listed is a model.
| Matchbox car | ||||
| Guitar | ||||
| Soccer video game | ||||
| Area of rectangle = length x width | ||||
| Clock | ||||
| Pen | ||||
| Tree | ||||
Get together with the other members on your team and write a list of as many types of models as you can. Include your list below.
To investigate how you inhale and exhale, we are going to make a model of a lung. With this model, we will be able to see how one of your lungs work, and measure air pressure changes to better understand how it works.
