Hello friends,
Today we will build a small Lungs Working Model for School Science Project. This is a creative idea for a school science project. It is very easy to make. To make it you will need drinking straw, Plastic bottle and balloon.
Anyone can make it for a science or school project.
The lungs serve as the respiratory organs for humans and many other animals. They extract oxygen from the air and transfer it to the bloodstream. They also expel carbon dioxide. In this experiment, the balloons on the straws act as the lungs, the straws act as the trachea, the bottle serves as the chest, and the balloon at the bottom of the bottle is the diaphragm. When the diaphragm is pulled, the pressure in the bottle becomes lower than atmospheric pressure, and the balloon “lungs” inflate. When the diaphragm is pressed, the processes reverse. Real lungs work similarly: when the diaphragm contracts, the volume of the chest cavity increases and air fills the lungs. Please note that this is a simplified model of the lungs and does not take into account the movement of the intercostal muscles.
