This activity explains the acidic, basic or neutral nature of different substances using pH paper. pH paper changes its colour when comes in contact with different substances.
This activity teaches us that particles of matter are in constant motion. The speed of
movement of particles depends upon their physical state whether they are solid or liquid or gaseous.In the previous activity 1.2, we have discussed
This activity helps us to understand the physical properties of solid substances or materials. The activity has been taken from the chapter 1 Matter in Our Surroundings Class 9 Science.
This activity explains the movement of particles of different substances in same medium and helps to understand how diffusion takes place at different rates.
