Dear Students,

For your next assignment, you need to create a 3D model of the respiratory system. Please research different ideas and methods online to get inspiration. You can use materials like balloons, clay, pipe cleaners, paper, or recycled items.

Make sure your model shows the main parts: trachea, bronchi, bronchioles, lungs, alveoli, and diaphragm. Be creative and think about ways to make it interactive, like showing how the lungs expand and contract.

Start your research and bring your ideas to class.

Silver: What happens in the alveoli?

Gold: How do circulatory and respiratory systems help maintain homeostasis?

Platinum: Predict what could happen to athletes at high altitudes.
