Summary
This study presents a cost-effective method for creating public health education models, including septic tank and oncometer models, using wire frames and plaster of Paris. These durable, waterproof models are ideal for health education in diverse communities.
Area of Science:
- Biomedical Engineering
- Public Health Education
Background:
- Effective health education requires accessible and durable teaching tools.
- Rural and suburban communities often face resource limitations for educational materials.
Purpose of the Study:
- To describe a simple and economical method for constructing educational models.
- To create models for teaching public health concepts (septic tanks) and physiological demonstrations (oncometers).
Main Methods:
- Utilizing a wire frame as a base structure.
- Covering the wire frame with plaster of Paris to form the model.
- Rendering models impervious to air and water using paraffin, varnish, or brushing lacquer.
Main Results:
- Successfully constructed functional models of septic tanks and oncometers.
- Demonstrated the models' durability and resistance to environmental factors after waterproofing.
- Highlighted the adaptability of the method for various educational needs.
Conclusions:
- The described method offers a practical and affordable approach to creating essential health education models.
- These models can significantly enhance public health outreach and physiological education, particularly in underserved areas.
- The waterproofing technique ensures longevity and usability in diverse settings.
