The NCERT Class 7 Science Chapter “Changes Around Us: Physical and Chemical” helps students understand the difference between physical changes and chemical changes that occur in everyday life. It explains how physical changes, like melting ice or tearing paper, do not form new substances, while chemical changes, such as rusting of iron or burning wood, result in new materials.
This chapter encourages students to observe and analyze changes happening around them, making science more practical and engaging. It builds a strong base for understanding key chemistry concepts in higher classes.
