Respiratory System
Project Proposal:
Description
BREATHING
We have a gallon water jug with the bottom cut off. There is a cut balloon attached to the bottom of the bottle to represent the flow of the air in and out. A strip of tape with an air-tight seal will have a straw attached in it. At the end of the straw, inside the jug, there will be two balloons that will inflate and deflate due to the balloon creating more air and less air inside the jug.
DIFFUSION
We will have a filter system to represent the diffusion of the oxygen from the muscles into the cells. We will use a filter and a DYE and water solution to show this.
Construction
BREATHING
DIFFUSION
Functions
BREATHING
The first model will represent the contracting and expanding of the lungs when a person breathes.
DIFFUSION
To represent the filtering of oxygen and carbon dioxide.
Materials
BREATHING
3 gallon bottle
Duct tape
plastic tubing
T tube
Large Balloons
DIFFUSION
Filter system
Filter
DYE
Water
Biology/Physics/Chemistry Principles
BREATHING
The expansion and the contracting of the balloons demonstrates the conservation law of gas. Instead of pressure building up in the bottle the air releases out of the straw into the air.
DIFFUSION
The dialysis paper will expel the waste (dye). This happens by the separation of colloidal particles from dissolved molecules.

Construction
BREATHING
- Attach Balloons to T tube with duct tape Airtight
- Cut 30 cm of plastic tubing
- Cut bottom off the 3 gallon bottle
- Slide tube through hole of cap and create air tight seal
- Cut neck of 1 large balloon, place over bottom of bottle and tape
DIFFUSION
- Place filter in the filter system
- Fill with water
- Put DYE in water
