Solar Water Purification - Science Investigatory Project

Summary

In their investigative project, the team explores solar water purification systems, focusing on three hypotheses related to the effectiveness of disinfection methods and aluminum sheets in purifying water from a local school. The study reveals that while the purification system alone is ineffective, the integration of aluminum sheets significantly improves water quality, reducing bacterial counts. The project emphasizes the importance of using renewable energy and recyclable materials in water purification, showcasing innovative solutions to enhance access to clean water.

Q & A

What is the main focus of the investigation?

The investigation focuses on a solar water purification system and its effectiveness in purifying school water.

What are the three key problems addressed in the study?

The problems include the effectiveness of the disinfection system, the role of aluminum sheets in purification, and the overall impact of these systems on school water.

What are the three hypotheses proposed by the investigators?

The hypotheses are: 1) The purification system alone is effective in purifying school water; 2) The integration of solar power is effective; 3) The use of aluminum sheets enhances purification.

What materials were used in the investigation?

Materials included plain sheets, silicon gum, bended metal sheets, mirrors, and PET bottles.

How was the water sample collected for the study?

Samples of water were taken from ADI SMCS High School, specifically from areas where the water quality was poor.

What was the outcome of hypothesis 1 regarding the purification system alone?

Hypothesis 1 was rejected, as the results showed significant bacterial presence in the purified water.

What were the findings related to hypothesis 2 about solar power integration?

Hypothesis 2 was also rejected, showing that the solar power integration did not effectively purify the school water.

Was hypothesis 3 accepted, and what did it involve?

Yes, hypothesis 3 was accepted, indicating that the integration of aluminum sheets in the disinfection system improved water purification.

What were the total coliform counts reported in the study?

The total coliform counts reported were 1.1 for the purification system, 1.1 again for solar integration, and 1.1 for the aluminum sheet integration.

What recommendations were made at the end of the presentation?

The investigators recommended avoiding mistakes by conducting thorough research and using recyclable materials to save costs and promote sustainability.
