Experience directly the usefulness of UV rays as a possible means of disinfecting water in remote communities. It is important to note that the concepts of purifying, disinfecting, and filtering, among others, are different and complementary to reduce the chances of consuming contaminated water. In this activity, we will explore the SODIS (Solar Disinfection) method, a cost-effective and efficient way to treat water using solar energy and transparent bottles. By understanding how specific UV rays from sunlight inactivate harmful viruses and bacteria, you'll learn how to protect yourself and others by harnessing the sun's natural power. Become a champion of clean water and make a difference in your community!
Develop these Key Competencies:
- Critical Thinking: Analyze how solar energy and specific UV rays can be utilized for water treatment.
- Systems Thinking: Understand the impact of clean water on communities and the environment.
Materials needed
- Transparent bottle (preferably PET)
- Tap water
- Sunny outdoor area with direct sunlight
