Create a functional 3D respiratory system model demonstrating inhalation and exhalation processes using simple materials like plastic bottles and balloons
Explain the structure and function of key respiratory components such as lungs, trachea, and diaphragm through hands-on model building
Illustrate the mechanics of breathing, including diaphragm movement and gas exchange, with a practical, visual model
Apply knowledge of respiratory health, oxygen intake, and carbon dioxide release to educational or science fair presentations
Respiratory system working model 3d making,
in this course introduces students to the structure and function of the human respiratory system through a hands-on, creative science project. In this course, learners will explore how breathing works by designing and building a 3D working model that demonstrates inhalation and exhalation. Using simple materials such as plastic bottles, balloons, straws, and clay, students will recreate key components like the lungs, trachea, and diaphragm. The model helps illustrate how the diaphragm’s movement causes air to enter and exit the lungs, making the process of gas exchange more understandable. Alongside practical construction, the course provides clear explanations of the importance of oxygen intake and carbon dioxide release in sustaining life. It also highlights the role of the respiratory system in maintaining energy and overall health. By the end of the course, learners will not only have a solid understanding of respiratory biology but also a functional 3D model suitable for classrooms, science fairs, or home-based learning. howtofunda
