Case Studies

Water purification plant process

This case study explains how a municipal water purification plant treats river water before supplying it to homes. It connects real-life water treatment steps with physical processes like sedimentation, filtration, and chlorination, helping Class 9 students understand separation techniques and their practical applications.

LPG cylinder leakage and diffusion

This case study explores how LPG spreads in a kitchen due to diffusion when a cylinder leaks. It connects real-life domestic safety with scientific concepts like diffusion, density of gases, and rate of mixing, helping students understand how physics applies to everyday life.
