Case Studies

Fossil fuel depletion

This case study examines the growing problem of fossil fuel depletion and its environmental impact. Using real examples from India’s energy consumption, students analyze how excessive use of coal, petroleum, and natural gas leads to resource exhaustion, pollution, and the urgent need for sustainable energy alternatives.

Nuclear energy advantages

This case study explains the advantages of nuclear energy using real examples from power generation systems. Students explore how nuclear power plants produce large amounts of electricity with low carbon emissions, helping countries like India meet energy demands while reducing environmental pollution.

Waste management system

This case study explores how an effective waste management system helps maintain environmental health and reduce pollution. Using an Indian city example, students analyze waste segregation, recycling, composting, and landfill systems to understand how communities manage biodegradable and non-biodegradable waste sustainably.

Food preservation chemicals

This case study explains how chemical preservatives help increase the shelf life of food products. Using examples from Indian households and food industries, students analyze the role of chemicals like sodium benzoate, salt, and potassium metabisulphite in preventing microbial growth and reducing food spoilage.

Sustainable agriculture model

This case study explains how sustainable agriculture models help farmers maintain soil fertility, conserve water, and improve crop productivity. Using an Indian village farming example, students analyze practices such as crop rotation, organic fertilizers, and mixed cropping that support environmentally friendly and long-term agricultural development.

Domestic electric wiring

This case study explores how domestic electric wiring safely distributes electricity in homes. Using a real-life Indian household example, students learn about live, neutral, and earth wires, parallel circuits, and safety devices like fuses and MCBs that protect homes from electrical hazards.
