human respiratory system working model 3d lung model for science fair project DIY howtofunda

Making respiratory system working model 3d, in this course offers students a hands-on approach to learning how the human body breathes and supplies oxygen. In this course, learners study the structure and function of the respiratory system, including the nose, trachea, lungs, and diaphragm. By designing and building a 3D working model, students can visualize how air enters the body, travels through the airways, and fills the lungs, while the diaphragm plays a key role in inhalation and exhalation. Using simple materials such as balloons, straws, and bottles, the model demonstrates the mechanics of breathing in an interactive way. This project makes complex biological processes tangible, helping students clearly understand oxygen intake, carbon dioxide removal, and the importance of healthy lungs. The activity also builds creativity, problem-solving, and presentation skills while reinforcing scientific knowledge. Perfect for science fairs, classroom experiments, and exhibitions, the course transforms anatomy into a fun and engaging learning experience. howtofunda
