  Class 6 Science Chapter 9 – Methods of Separation in Everyday Life NCERT Curiosity 2026-27 | Detailed Notes, NCERT Questions & Answers, Important Questions, MCQs & Worksheet Chapter Overview In everyday life, we often find two or more substances mixed together. We separate them when we need to remove an unwanted component or when we want to collect useful components separately. The method of separation is selected according to the properties in which the components differ. 📘 1. Why Do We Separate Substances? A mixture contains two or more substances together. In many situations, the components of a mixture have to be separated. Separation may be needed to remove an unwanted or harmful substance, or to obtain useful components separately. Removing unwanted material, such as stones from rice or pulses. Obtaining useful products separately, such as butter from curd. Cleaning materials before use, such as removing unwanted particles from water. Key Idea...

  Class 6 Science Chapter 8 – A Journey through States of Water NCERT Curiosity | Class 6 Science | Chapter 8 | NCERT Solutions | 2026–27 📘 Previous Chapter Class 6 Science Chapter 7 – Temperature and its Measurement 💧 CHAPTER IDEA Water exists as solid, liquid and gas. Heating and cooling can change water from one state to another. Clean Notes – A Journey through States of Water 1. Three States of Water Water is the same substance in different states. Solid → Ice   |   Liquid → Water   |   Gas → Water Vapour Ice has a fixed shape. Liquid water flows and takes the shape of its container. Water vapour spreads through available space. 2. Melting and Freezing Melting: Solid → Liquid on heating. Freezing: Liquid → Solid on cooling. 3. Evaporation Evaporation is the change of liquid water into water vapour. It can happen even below the boiling point. Liquid water → Water vapour 4. Factors That Affect Evaporation Larger exposed surface area → faster evap...

  Class 6 Science Chapter 7 – Temperature and its Measurement NCERT Curiosity | Class 6 Science | Chapter 7 | NCERT Solutions | 2026–27 📘 Previous Chapter Read: Class 6 Science Chapter 6 – Materials Around Us CHAPTER IDEA Temperature tells us how hot or cold a body is. A thermometer gives a reliable way to measure temperature. 🌡️ Clean Notes – Temperature and its Measurement 1. Hot or Cold? Our sense of touch cannot always tell us correctly whether something is hot or cold. The same water may feel different to different hands after they have been exposed to warm or cold water. Key Idea: We cannot always rely on touch to judge temperature accurately. 2. Temperature Temperature is a reliable measure of the hotness or coldness of a body. A hotter body has a higher temperature than a colder body. Higher temperature → Hotter   |   Lower temperature → Cooler 3. Thermometer A thermometer is a device used to measure temperature. Two common types...

Class 6 Science Chapter 6 – Materials Around Us NCERT Curiosity | Class 6 Science | Chapter 6 | 2026–27 📘 Previous Chapter Read: Class 6 Science Chapter 5 – Measurement of Length and Motion CHAPTER IDEA Everything around us is made of materials. Different materials have different properties, and these properties help us choose the right material for a particular use. 1. Objects and Materials An object is something that we use or see. The material is the substance from which an object is made. Example: Chair → Object Wood, plastic or metal → Material The same object can be made from different materials. Similarly, one material can be used to make many different objects. 2. Why Do We Group Materials? There are many materials around us. We group them according to their similarities and differences . It makes materials easier to study. It helps us compare materials. It helps us choose the right material for a particular use. 3. Important Properties...

CHAPTER IDEA We use measurement to describe length and distance. We use reference points to describe whether an object is at rest or in motion. 1. How Do We Measure? Measurement means comparing an unknown quantity with a known unit. A measurement is written using a number and a unit. NUMBER + UNIT Example: 13 handspans → 13 is the number and handspan is the unit. In earlier times, people used body-based units such as handspan, foot, finger width, arm length and stride. These were not uniform because body sizes differ. WHY STANDARD UNITS? A standard unit gives the same measure of th...
