The NCERT Class 7 Social Science Chapter “Changes Around Us: Physical and Chemical” helps students explore how materials and substances change in our surroundings. It explains the difference between physical changes (like melting, freezing, or dissolving) and chemical changes (such as rusting, burning, or cooking).
Through real-life examples and experiments, students understand the scientific principles behind these transformations. The chapter builds awareness about natural and man-made changes and their impact on the environment. It encourages observation, analysis, and appreciation of everyday science.
