TOPIC: CLASSIFICATION OF MATTER
CONTENT 1: States of matter
State of Matter:
Matter can be classified into the following group:
- Living and non-living things
- Using state of matter
- Using physical criteria like size, weight, texture, shape, color, smell, taste.
There are three states of matter which are solid, liquid and gas.
SOLID:
The particles of solid are arranged in an orderly manner. A strong inter-molecular force holds the particles together. The particles are very much close together. Solids have definite shapes, volume and fixed mass. Examples of solid are salt,glass, metal, rock, wood, sugar, ice-block; stone e.t.c. solid undergoes transnational motion and oscillatory motion
.
LIQUID:
The particles of a liquid are not very close together. Liquid particles are a bit free to move about because of the moderate intermolecular force between particles. Liquid does not have a definite shape but takes the shape of the container. Liquid are fluid which flows or diffuse in all directions. Examples are water, blood, ink, urine. Liquid have definite volume, fixed mass. Liquid cannot be compressed or squeezed into a smaller space. Liquids undergo three kinds of motion, vibration, rotational and translational.
GAS:
The particles of gas are very far apart because of the very weak intermolecular force holding the particles. They move about freely at great speed. Gases have no definite shape, volume but have fixed mass. Gases can be compressed. Examples of gases are air, ammonia, steam, oxygen e.t.c.
Change of state
When solid water [ice] is heated, its particles move faster and break away from the ordered arrangement. The solid melts to become a liquid. The melting point of a substance is the temperature at which solid changes to liquid. The boiling point of a substance is the temperature at which liquid changes to gas
Presentation
The topic is presented step by step
Step 1:
The class teacher revises the previous topics
Step 2.
He introduces the new topic
Step 3:
The class teacher allows the pupils to give their own examples and he corrects them when the needs arise
Evaluation:
- List all the states of matter you know
- How will you identify matter?
- Differentiate between solid and liquid.
- How can we change a solid to liquid?
- What is boiling point?
- List three properties each of solids liquids and gases.
Conclusion :
The class teacher does the necessary corrections and he or she goes round to mark .
Assignment:
- Explain the season of the year in your country.
- Write the names of the nine planets in order of their average distance from the sun.
- List all the states of matter you know
- How will you identify matter?
- Differentiate between solid and liquid.
- How can we change a solid to liquid.
