Start Class 9 Science Chapter 5 — Exploring Mixtures and Their Separations — from the new NCERT Exploration book (2026-27). This lecture covers what mixtures are, homogeneous vs heterogeneous mixtures, Activity 5.1, and the Tyndall effect with a clear comparison of solution, colloid, and suspension. ___________________________________________ ✅ WHAT YOU'LL LEARN IN THIS LECTURE: What is a mixture? Definition and examples (salt + water, milk + water, bhujia) Types of mixtures — homogeneous vs heterogeneous: meaning of uniform vs non-uniform composition Activity 5.1 — three beakers experiment: salt water, chalk powder water, milk water Four observations: particle visibility, filter paper separation, settling with time, light path Tyndall effect: scattering of light by particles — which mixtures show it and which don't True solution, colloid, and suspension — full comparison with properties and examples Particle size ranges: true solution ( Less than 1 nm), colloid (1–1000 nm), suspension ( More than 1000 nm) ___________________________________________ 📚 This lecture is for Class 9 students of CBSE, UP Board, Haryana Board, Bihar Board, MP Board, and all state boards following the new NCERT Exploration book for Session 2026-27. Chapter 5 of Exploration corresponds to Chemistry Chapter 1. ___________________________________________ 👨‍🏫 ABOUT THE TEACHER: Tarif Bhayana brings Class 9 and Class 10 Science to life with clear, engaging explanations in Hindi.
