Case Studies

DNA fingerprinting case

This case study explores how DNA fingerprinting is used in real-life crime investigations and paternity disputes in India. Students analyze a forensic scenario involving DNA samples and learn how unique DNA patterns help scientists identify individuals, solve legal cases, and establish biological relationships.

Heredity in family traits

This case study explains how family traits such as eye colour, dimples, or attached earlobes are passed from parents to children. Using a real-life family example, it helps Class 10 students understand heredity, dominant and recessive traits, and how genes influence observable characteristics.

Environment conservation project

This case study explores how students participate in an environment conservation project through activities like tree plantation, waste management, and biodiversity awareness. It highlights real-life school initiatives in India and connects them with ecological concepts such as sustainable resource use, biodiversity protection, and environmental responsibility.

Power generation in thermal plant

This case study explains how electricity is generated in thermal power plants using coal, steam turbines, and generators. Through a real-life Indian power plant scenario, students explore energy conversion, electromagnetic induction, and electricity distribution, connecting physics concepts with large-scale electricity production.

Electric short circuit case

This case study explores how an electric short circuit occurs in household wiring and why safety devices like fuses and circuit breakers are essential. Through a real-life scenario in an Indian home, students analyze the causes, risks, and preventive measures related to excessive current flow.

Magnetic effects in electric motor

This case study explains how electric motors work using the magnetic effects of electric current. Through real-life examples such as electric fans and water pumps commonly used in Indian households, students explore how current-carrying conductors interact with magnetic fields to produce motion.
