Matter is anything that has mass and occupies space. Learn about its properties, the particulate nature of matter, diffusion, states of matter, and how temperature and pressure affect its behavior through simple experiments.
Chapter 1- A Detailed Guide to “Matter and Its Properties” Activities for Class 9 Students Read MoreLearn how gas particles move and mix through this simple activity using an incense stick. Observe how its smell spreads in the air.
Class 9 Science- Chapter 1- Matter In Our Surroundings – Activity 1.3: Observing Diffusion of Incense Stick Smell in Air Read MoreThis experiment demonstrates that matter is made up of tiny particles. By diluting potassium permanganate or Dettol in water, observe how the particles spread evenly even after repeated dilution.
Class 9 Science- Chapter 1- Matter In Our Surroundings – Dilution Experiment: Demonstrating the Small Size of Matter Particles Read MoreCompare evaporation rates under different conditions like wind, enclosed spaces, and rainy days. Learn how surface area, temperature, and humidity affect evaporation.
Class 9 Science- Chapter 1- Matter In Our Surroundings – Activity 1.14: Exploring Evaporation Rates Under Different Conditions Read MoreStudy sublimation by heating camphor. Observe how a solid changes directly to a gas without becoming liquid, and notice the crystalline deposits on cooling.
Class 9 Science- Chapter 1- Matter In Our Surroundings – Activity 1.13: Sublimation Experiment with Camphor Read MoreIdentify solids, liquids, and gases in your surroundings. Observe their properties, like fixed shape and volume in solids, fluidity in liquids, and compressibility in gases.
Class 9 Science- Chapter 1- Matter In Our Surroundings – Activity 1.11: Observing States of Matter in Daily Life Scenarios Read MoreObserve how liquids flow and maintain a fixed volume by pouring them into different-shaped containers like glasses or bowls.
Class 9 Science- Chapter 1- Matter In Our Surroundings – Activity 1.10: Investigating the Fluidity and Volume Retention of Liquids Read MoreInvestigate solids’ properties like definite shape, fixed volume, and incompressibility using everyday objects like a book or pen.
Class 9 Science- Chapter 1- Matter In Our Surroundings – Activity 1.9: Investigating the Properties of Solids Like Definite Shape and Incompressibility Read MoreObserve surface tension by gently pressing water with your fingers. Learn how cohesive forces create a thin “film” on water’s surface.
Class 9 Science- Chapter 1- Matter In Our Surroundings – Activity 1.8: Testing the Surface Tension of Water Using Fingers Read MoreTest the strength of solids like an iron nail, chalk, and rubber band. Learn how bond strength affects their properties.
Class 9 Science- Chapter 1- Matter In Our Surroundings -Activity 1.7: Testing the Strength of Bonds in Different Solids Read More
