The respiratory system allows us to breathe by taking in oxygen and releasing carbon dioxide. It has different parts such as the nose, lungs, trachea, and diaphragm. For students, learning about this system is very important in biology and health education.
Making a project on the respiratory system is a great way to understand how it works. Whether you’re in class 5 or class 12, there are many fun and easy ideas you can try at home or for a science fair.
In this blog, you will find 100 creative and unique respiratory system project ideas. These are divided into different categories like models, working experiments, group activities, and more. Let’s explore!
