Case Studies

Biotechnology in agriculture

This case study explores how biotechnology is transforming modern agriculture through genetically modified crops and improved farming practices. Using the example of Bt cotton cultivation in India, students analyze how genetic engineering helps farmers control pests, increase crop productivity, and reduce pesticide usage while raising ecological and economic considerations.

Ecosystem imbalance case

This case study explores how disturbances in an ecosystem can create ecological imbalance through changes in food chains and biodiversity. Using an Indian river ecosystem example, students analyze how pollution, species decline, and human activities disrupt ecological stability and affect producers, consumers, and decomposers.

Human reproduction hormonal case

This case study analyzes how hormones regulate human reproduction through a real-life medical consultation scenario. It explores the coordinated role of the hypothalamus, pituitary gland, and reproductive organs in controlling ovulation, menstrual cycles, and pregnancy using hormones like FSH, LH, estrogen, and progesterone.

Photoelectric effect experiment

This case study explores the photoelectric effect through a laboratory experiment conducted by physics students studying modern physics. It explains how light of different frequencies causes electron emission from a metal surface, highlighting concepts such as threshold frequency, stopping potential, photon energy, and Einstein’s photoelectric equation.

AC vs DC supply

This advanced case study analyzes the practical differences between Alternating Current (AC) and Direct Current (DC) in modern power systems. Using examples from India’s electricity grid and long-distance transmission projects, students evaluate efficiency, transmission losses, and technological choices behind AC and HVDC systems.

Nationalism in India movement

This case study explores how different movements like Non-Cooperation and Civil Disobedience helped unite Indians against British rule. Through a realistic classroom investigation of historical events, students analyze how mass participation, boycotts, and non-violent protest strengthened the nationalist movement in India.
