In this video, we explain Activity 1.7 from Class 9 Science – Matter in Our Surroundings.
In this activity, we take an iron nail, a piece of chalk, and a rubber band and try breaking them by hammering, cutting, or stretching. Through this experiment, we understand that particles of matter have a force of attraction between them.
👉 Iron nail is difficult to break because its particles are held together with greater force.
👉 Chalk breaks easily, so its particles have less force compared to iron.
👉 Rubber band can stretch, showing flexibility in particle arrangement.
This activity helps us understand that the strength of force of attraction varies in different substances.
📚 Perfect for Class 9 students preparing for exams.
