Nature of Matter: Elements, Compounds, and Mixtures | Class 8 Science | Chapter 8 | CBSE

This module introduces secondary students to the fundamental classification of matter into elements, compounds, and mixtures. It explores how substances interact physically and chemically, using everyday examples and laboratory experiments to distinguish between uniform mixtures, pure substances, and chemical compounds. We recommend you to watch the resource and microlearning videos links below for a deeper understanding of this topic. They are carefully selected to support your learning journey.
