B.Ed Practicum (Sem-4) English Version, EVS~Visit To Polluted Sites And Preparation Of A Report,

Summary

This script outlines a report on the observation and analysis of a local water body, highlighting the scarcity of fresh water on Earth. It emphasizes the importance of addressing water pollution, detailing the methodology for data collection and analysis. The report includes observations of water quality parameters, nearby environmental factors, and their impact on the ecosystem. It concludes with a call for action to protect this vital resource.

Takeaways

• 📍 The importance of selecting a local water body as a site for pollution study due to its visibility and impact on the community.
• 💧 Freshwater is a limited resource, with only 2% of the Earth's water being accessible as groundwater, highlighting the scarcity of this vital resource.
• ❄️ The majority of the Earth's water is in the form of icebergs and frozen water in polar regions, which is not readily usable.
• 🔍 The objective of the study involves psychological observation, data collection, and regular monitoring of the water body by a named observer.
• 📊 Data is organized into tables focusing on economic specimens, plants, animals, pollutants, and soil conditions.
• 🌡️ Observations include the nature of the water, its temperature, color, pH levels, and the presence of various organisms and chemicals.
• 🏞️ The study also considers the regional pollution, habitat, agricultural fields, topography, soil, average rainfall, and temperature.
• 🏭 The influence of industries on the water body is noted as a significant factor in the study of water pollution.
• 📈 Data analysis involves the use of data tables and visualizations to understand the extent and nature of pollution.
• 📝 The report includes a reference section for further reading and an acknowledgment section to recognize contributions to the study.

Q & A

What is the significance of selecting a local water body as a site for pollution observation?

Local water bodies or tanks are often chosen as they are easily accessible public places that can serve as clear examples of local pollution.

What is the percentage of fresh water available on Earth, and where does it primarily exist?

Only 2% of the Earth's water is fresh, with most of it being groundwater. The remaining 1.5% exists as icebergs and frozen water in polar regions.

Why is it important to study the problem of water pollution?

Water is a limited resource, and studying water pollution helps in understanding its impact on this precious resource and aids in developing strategies for conservation and protection.

What are the objectives of the observation at nearby places mentioned in the script?

The objectives include data collection, identifying the name of the water body, the name of the organization responsible for regular filtration, and fulfilling the role of an observer.

What are the key parameters to be studied when observing the nature of water in a water body?

Key parameters include temperature, color, pH level, presence of organisms, floating and submerged plants, and biological oxygen demand.

What kind of information is gathered in Table 3 of the observation at nearby places?

Table 3 focuses on regional pollution, habitat, agricultural fields, topography, soil, average rainfall, average temperature, and industries.

How is the data collected during the observation analyzed?

The data is analyzed using data tableau, which helps in visualizing and understanding the patterns and trends in the collected data.

What is the purpose of the reference section in the report?

The reference section provides credibility to the report by citing sources of information and data used during the study.

What is the role of an observer in the water body observation process?

The observer is responsible for collecting data, noting observations, and ensuring the accuracy and reliability of the information gathered.

How can the information from the script be used to raise awareness about water pollution?

The detailed observations and data analysis can be used to create educational materials or presentations that raise public awareness about the issue of water pollution.
