Mixture- Complete Lesson Plan of Class 9th

In this post we are providing pdf of complete Integrated Lesson plan of Topic Mixturefor 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 mixture.
2. Students will be able to describe types of mixture.
3. Students will be able to distinguish between homogeneous and heterogeneous mixtures.

#### Teaching Aids

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

#### Introductory Questions

 PUPIL-TEACHER ACTIVITY STUDENT’s RESPONSE Q1. What do we get from cow? Milk Q2. Name the constituents of milk? Water, fat, proteins, etc. Q3. What is formed when more than one type of matter are combined? Mixture

#### Statement of Aim

So, today we are going to study the topic ‘Mixture’

#### Presentation

##### Teaching point 1: Definition of mixture

Mixtures are constituted by more than one kind of pure matter, known as substances.
In other words, Mixture contains more than one substance.

##### Teaching point 2: Types of mixtures

There are two types of mixtures on the basis of nature of the components that form a mixture:
1. Homogeneous mixture- Mixture which have uniform composition throughout, are called homogeneous mixtures.
They possess same properties and combination throughout their mass. E.g. Sugar in water
2. Heterogeneous mixture- Mixtures which contain physically distinct parts and have non-uniform combinations are called heterogeneous mixtures.
These mixtures possess different properties and combinations in various parts.
E.g. mixtures of salt & sulphur, oil & water etc.

##### Teaching point 3: Activity on types of mixtures
• Take two beakers.
• In first beaker, take 1 tsp of salt and add water to it. Mix it well and say this as group A.
• Fill second beaker with water and add 1 tsp oil into it. Say this as group B.
• You will notice that, group A mixture has obtained uniformity. Such mixtures are homogeneous mixtures.
• Mixture of group B is still non-uniform. You can clearly see both oil and water in different layers. Such mixtures are called heterogeneous mixtures.

#### Blackboard Summary

• Mixtures are made up of more than one substances.
• Mixtures are of two types- homogeneous and heterogeneous.
• Homogeneous mixtures have uniform composition.
• Heterogeneous mixtures are non-uniform in composition.
• Properties of homogeneous mixtures are same throughout their mass.

#### Evaluation Questions
