Initial design and shaping of lung model
Description:
My partner and I began the project by brainstorming and planning the basic structure of the lung model. We worked together to shape modeling clay into a rough lung form while discussing how we would eventually create a hollow interior. At this stage, we focused on establishing the overall design and identifying where the airway would be placed.
PLTW STEP:
Imorove Prototype
Outcome:
A basic lung shape was created through teamwork, but it was still solid and needed modifications to become functional.

Creating airway pathway
Description:
My partner and I worked on adding an airway system using a straw to represent the trachea. We carefully inserted and adjusted the straw to ensure it was positioned correctly within the clay structure. Together, we tested how stable it was and discussed how airflow would be demonstrated through the model.
PLTW STEP:
Develop Solution
Outcome:
The airway was successfully integrated, but the clay remained soft and unstable around the structure.

Attempting hollow structure
Description:
We focused on creating a hollow interior to better represent lung function. My partner and I carefully removed clay from the inside while trying to maintain the outer shape. We tested airflow through the straw and observed how the structure responded to changes. The process required coordination to avoid collapsing the model.
PLTW STEP:
Test and Evaluate
Outcome:
The testing helped us identify improvements we can make on the model and it ended up failing

Silicone testing on lung model
Description:
We experimented with silicone as a flexible outer layer for the lung model. My partner and I applied silicone to parts of the 3D structure to test how it would hold shape and simulate lung expansion. We observed how the materials interacted and noted issues with uneven coverage and soft structural support.
PLTW STEP:
Design Improvement
Outcome:
Silicone showed potential for flexibility, but the 3D base made application inconsistent.

Improving structure stability
Description:
My partner and I focused on reinforcing the lung model to improve durability and prevent collapse. We thickened parts of the clay walls and repositioned the straw to create better support for airflow. These adjustments improved stability slightly, but further refinement was still needed.
PLTW STEP:
Evaluate
Outcome:
The model became more stable overall, but still required additional structural improvements.
