1. What body system did you pick to build as a working model?

Nicholas, Luke, and I chose to build a working model of the respiratory system.

2. Why have you decided to build this body system as a working model?

We chose the respiratory system because we displayed a curiosity towards it and found it extremely intriguing and interesting. Similarly, the model will be based on simpler principles than other systems, for example an enlaced chamber with a rubber sheet acting as a diaphragm and a balloon as the lung.

3. What materials are you going to need to complete your build?

Materials:

– 1 Watson’s water 2 litter bottle

– 1 meter of 1cm diameter of plastic tubing.

– One 1 cm diameter Y-connecter.

– 2 small balloons

– 3 large balloons
