Activity 2.11 Class 10 Science
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.
NCERT Class 9 Science Activity 1.3 Explanation
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
Activity 1.9 Class 9 Science
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.
Matter in Our Surroundings Activity 1.4 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.
Activity 1.7 Class 9 Science
This activity explains how strongly, particles of matter are held in different materials and comparison of strength of intermolecular force between them.
Activity 2.1 Class 10 Science Acids, Bases and Salts
Aim of the activity
To test the acid bases using different indicators and record the observation to understand the acidic and basic nature.
Activity 2.8 Class 10 Science Acids , Bases and Salts
The activity has been taken from the chapter 2 Acids, Bases and Salts class 10 science. We will discuss electrical conductivity of acids, bases and other organic compounds.
