Case Studies

Photosynthesis in greenhouse

This case study explores how greenhouse farming improves photosynthesis by controlling factors such as light, temperature, humidity, and carbon dioxide. Through a real-life example of modern Indian agriculture, students understand how environmental conditions influence plant growth and crop yield.

Refraction in spectacles

This case study explains how refraction in spectacle lenses helps correct common vision defects such as myopia and hypermetropia. Through a real-life scenario of students using spectacles, it connects the physics concept of refraction with the functioning of concave and convex lenses in everyday life.

Dialysis machine functioning

This case study explains how a dialysis machine works when kidneys fail to filter blood properly. Using a real-life hospital scenario, students learn how diffusion through a semi-permeable membrane removes waste products such as urea from blood, demonstrating the role of excretion and artificial kidney technology in human health.

Life processes in marathon runner

This case study explores how life processes such as respiration, circulation, and energy release support a marathon runner during a long-distance race. Through a real-life sports scenario, students understand how oxygen supply, glucose metabolism, and muscle activity help the body maintain energy and endurance during intense physical activity.

Corrosion in iron bridge

This case study explains how corrosion affects iron bridges in real life. Through a practical Indian scenario, students explore the chemistry behind rust formation, factors that accelerate corrosion, and preventive measures used in engineering. It connects chemical reactions with infrastructure safety and environmental conditions.

Antacid working in stomach

This case study explains how antacid tablets relieve acidity by neutralizing excess stomach acid. Through a real-life scenario of indigestion after eating spicy food, students analyze the chemistry of acid–base neutralization, chemical reactions of antacids, and decision-making related to dosage and effectiveness.
