Introduction
Hi, this webquest will allow you to learn about how the lungs work.
The lesson will be introduced with video entitled Lungs/Anatomy of Lungs/Lung Song
https://www.youtube.com/watch?v=-plG8W8JZ0o&list=RD-plG8W8JZ0o
Task
1. Watch a video entitled "Lungs/Anatomy of Lungs/Lung Song"
2. Identify the functions of the lungs in our bodies.
3.Create a model of the lungs.
Process
1.Go to the following site and watch the video https://www.youtube.com/watch?v=-plG8W8JZ0o&list=RD-plG8W8JZ0o
After watching the video you will ask various questions about the video. These includes:
Where does air goes after it enters the mouth before it reaches the lungs?
Identify some parts of the lungs.
2. Identify the functions of the lungs in our bodies.
3. Working collaboratively in groups , you will create a model of the lungs. The steps are as follows:
- 1 clear plastic bottle
1 large balloon
2 small balloons
clay or play dough
1 plastic straw
2 rubber bands
1. Cut the bottom off of the bottle, leaving a portion of the bottom edge on.
2. Cut the top part of a large balloon and discard. Tie the stem of the balloon in a knot and slip the open end over the bottom of the bottle.
3. Attach the small balloons to the straw with a rubber band and insert the straw, balloon-side down into the bottle.
4. Seal the top around the straw with clay or play dough.
5. Let the children experiment by pulling down on the knotted balloon. The
small balloons will inflate the same as when you expand your chest and
inhale air through the nose.

Conclusion
That breathing is a mechanical process by which there is an interaction
between the organism and the surrounding air; the lungs and other parts
of the respiratory system perform this mechanical process; that we
breathe air (a mixture of gases composed of oxygen, nitrogen, and a
minute amount of carbon dioxide); oxygen, the gas the body needs, comes
from the air; the lungs and other parts of the respiratory system remove
carbon dioxide from the blood as a waste product and that this excess
carbon dioxide is exhaled.
