space station with astronaut science project model making using waste materials howtofunda

space station model making, in this course teaches students how to design and build a realistic three-dimensional model that demonstrates how the human respiratory system functions. Through hands-on learning, students explore the structure and roles of key organs such as the nose, trachea, lungs, and diaphragm. The course explains how air enters the body, oxygen is exchanged with carbon dioxide, and breathing occurs through the movement of the diaphragm. Using simple materials like balloons, straws, plastic bottles, and clay, learners create a working model that shows lung inflation and deflation. This interactive project helps students visualize complex biological processes in an engaging and easy-to-understand way. Ideal for science fairs and biology lessons, the course combines creativity and education to enhance understanding of human anatomy, breathing mechanisms, and the importance of a healthy respiratory system. howtofunda
