Introduction: Students members of Class VIII of the Environment Club
recently conducted an exciting and educational experiment involving
solar stills. Solar stills are devices that utilize solar energy to
purify water by distillation, which is a critical process for producing
clean drinking water. The objective of this experiment was to understand
the principles of solar distillation, as well as its potential for
providing a sustainable source of fresh water. Students used the simple
apparatus to conduct this experiment |
|
- The students constructed a simple solar still using readily
available materials. They created a small pit in the ground and
placed a container at the center of it. A sheet of transparent
plastic was placed over the pit, ensuring that it covered the
container.
- Contaminated water was poured into the container, and the
plastic sheet was securely sealed to prevent any air from entering.
- Over the course of several days, the students documented
the condensation that formed on the underside of the plastic sheet.
They also kept track of the amount of pure, distilled water
collected in the container.
- The experiment was carried out on sunny days to maximize
the effectiveness of the solar still.

The Class VIII students' experiment with solar stills provided a
valuable hands-on learning experience. It reinforced the principles of
solar distillation and highlighted the potential of this method for
producing clean drinking water, particularly in areas with limited
access to clean water sources. The experiment also encouraged the
students to consider the importance of sustainable solutions (SDG-
SUSTAINABLE DEVELOPMENT GOAL) to address water scarcity issues.This
activity not only enriched the students' understanding of science and
environmental concepts but also instilled in them a sense of
responsibility toward addressing water-related challenges. It is an
excellent example of how practical, real-world experiments can foster
knowledge and awareness among young learners. |

The students concluded that solar stills offer a promising,
eco-friendly solution for producing clean water and may be especially
useful in arid regions where clean water sources are scarce. The
experiment was a resounding success, leaving the students eager to
explore more innovative ways to address environmental challenges in the
future. |
