States of Matter lesson plan- Class IX NCERT with pdf

In this post we are providing pdf of complete Integrated Lesson plan of Topic States of matter’ for Pupil teacher of Bachelor of Education from Science class 9th of NCERT textbook. This lesson plan is suitable for both microteaching as well as macro-teaching.

#### General Aims

1. To develop interest of students in physical science.
2. To develop an inquiry spirit in the students.
3. To help students to see the physical science in relation to the rest of the culture.
4. To develop interest in questioning.
5. To develop critical thinking and scientific attitude.
6. To develop supervisory ability in students.
7. To develop problem solving skills in students.
8. To make the students aware about inventions in the field of physical science and acquaint them with the knowledge of different streams of physical science.

#### Specific Objectives

1. Students will be able to define matter.
2. Students will be able to describe various states of matter.
3. Students will be able to compare different states of matter.

#### Teaching Aids

Chart, Roller board, pointer and other useful classroom equipments.

#### Introductory Questions

 PUPIL-TEACHER ACTIVITY STUDENT’s RESPONSE Q1. How can you define matter? matter is something that has some mass & occupies some space. Q2. In how many states does it exists? three states Q3. Name the fourth state of matter. Plasma (problematic)

#### Statement of Aim

So, today we are going to study the topic ‘states of matter’.

#### Presentation

##### Teaching Point 1: THE SOLID STATE
• Matters existing in solid state have definite shape, distinct boundaries and fixed volumes.
• They have negligible compressibility.
• Solids have tendency to maintain their shape when an external force is applied.

Exception-

• Rubber band- A rubber band changes its shape under force and regains the same shape when the force is removed. If excessive force is applied it breaks.
• Sponge- It is a solid yet we are able to compress it because sponge has minute holes, in which air is trapped, when we press it air is expelled out and we are able to compress it.
##### Teaching Point 2: THE LIQUID STATE

Matters existing in liquid state have no fixed shape but have fixed volume.

• The take up the shape of container in which they are kept.
• Liquid flow and change shape, so they are not rigid but fluid.
• Solid, liquid and gas can diffuse into liquids. The rate of diffusion of liquids is higher than that of solids, because particles in liquid state move freely and have greater space between each other as compared to particles in the solid state.
##### Teaching Point 3: THE GASEOUS STATE
• Gases are highly compressible and have large spaces between them as compared to solids and liquids.
• The liquefied petroleum gas (LPG) cylinder in our home or oxygen cylinders in hospitals is compressed gas.
• Compressed natural gas (CNG) is used as fuel these days.
• Due to high compressibility of gases, large volumes of gas can be compressed into a small cylinder and transported easily.
• In gaseous state, particles move randomly at high speed.
• Matters exist in two more forms: plasma and Bose-Einstein condensate.
• Plasma state-This state consists of super energetic and super excited particles. These particles are in the form of ionized gases. g. FLourescent tube, neon sign bulbs.
• Bose-Einstein condensate- This state is formed by cooling a gas of extremely low density.

#### Blackboard Summary

• Matter exists in 5 states.
• Solids have definite shape, distinct boundaries and fixed volumes.
• Rubber band and sponge are exceptional cases of solids.
• Liquids have no fixed shape but have fixed volume.
• Gases are highly compressible and have large spaces between them.

#### Classroom Supervision

Pupil-teacher will supervise the problem of the students and solve it.
