B.Ed. Mantra -b.ed lesson plan pdf

TOPIC: Physical and Chemical Changes GRADE: 7^th

TIME ALLOTED: 25 Minute SUB TOPIC: Physical Change

TYPE OF LESSON PLAN: Simulation Lesson Plan

BRIEF OVERVIEW:

In this chapter we will study about the changes that are happening around us and their various effects and types. This will immensely help in learning the changes that are based on these similarities. This chapter also explains about the different activities that can help us to classify the changes that are irreversible or reversible in nature. We can clearly understand about two different types of changes i.e. Physical and chemical change, Crystallisation, Rusting of Iron.

Content to be taught:

a. Physical change

b. Characterstics of Physical Change.

TOPIC: Physical and Chemical Changes GRADE: 7^th

TIME ALLOTED: 25 Minute SUB TOPIC: Physical Change

TYPE OF LESSON PLAN: Simulation Lesson Plan

Specific Objectives:

By the end of the lesson pupil will be able to:

Knowledge: define various changes around us.

Understanding: explain:

(i) Physical changes

(ii) Characterstics of Physical Changes

Application: illustrate characterstics of different knid of changes by providing examples.

Affective Domain: approve the concept of Physical change in daily life.

Pyschomotor Domain: demonstrate activities for better understanding of physical change and its characterstics.

CONCEPT MAP

MIND MAP

TEACHING METHOD:

Inquiry Method: For previous knowledge , defining term change.

Lecture cum Demonstration Method: By showing various gif and videos PT will explain characterstics of physical change.

Teaching Aid:

Powerpoint Presentation

Digital Flip Book

Animated videos

Linking with previous knowledge including daily life experiences:

In order to link with previous knowledge and to further motivate the students the pupil teacher will show one video where several day to day life changes will take place:

Day to Night

Sunrise and Sunset

Then PT will show one gif where someone is making a paper boat and then pupil teacher will ask students that what they have noticed.

“The student will say that the shape of the paper has changed.”(Expected)

Now, pupil teacher will ask what type of change is this? (Problematic)

The pupil teacher and students will discuss the answer.

Announcement of the Topic:

Finding the students unable to give proper answer the Pt will say

“Well Students, in today’s class we will learn about the types of changes.”

The Pupil teacher write down the name of the topic on the blackboard.

TEACHING LEARNING PROCESS

Teaching Learning Point: Define term changes

Learning Process : Inquiry Approach

Teaching Learning Process : PT will first show one video and ask students to observe carefully and infer what you understand. Then PT will ask students to share their observation. After getting responses PT will explain in this video we saw changes that takes place in our day to day life.

PT will explain Changes is a universal phenomenon and it occurs continuously.

Skill Develop: Inquiry skill

Multimedia used:

Teaching Learning Point: Explain physical change

Learning Process : Inquiry Approach

Teaching Learning Process: PT will show one image of paper then show one video where paper folding takes place to convert it into boat.

Ask students to infer the result. After getting several responses.

PT will play one song and ask students to listen it carefully and note down the important points. PT will ask students, try to frame define of physical change. After getting responses PT will conclude the define of Physical Change on the board.

“The change in which only physical properties of a substance get changed and no new substance is formed.”

Skill Develop: Auditory skills

Multimedia used:

Teaching Learning Point: Illustrate characterstics of physical change

Learning Process: Lecture cum Demonstration method

Teaching Learning Process: To further motivate the students PT will show gif of stretching rubber band and tearing of paper and ask to student to frame hypothesis what you observe.

Then PT will explain When we stretch a rubber band only its shape and size will change this shows change takes place only in their physical aspect.

This is our first characterstics 1:

“in Physical change only some of the physical properties like shape , size, colour and no new substance is formed.

PT will show one more video of wrapping the aluminium foil and ask students what do you observe here. Some will say crushing of foil whereas some will say change in the shape of foil. After appreciating the responses of students.

PT will start explaining and write the same on the blackboard.

Characterstics 2:

In physical change, Chemical composition of a substance remains same during a physical change.

We can say No change in chemical composition will takes place.

Characterstics:

To make class more interesting and to explain next property PT will show 2 images where one is of boiling water and 2^nd is of melting of icecream.

PT will ask students to keenly observe and tell what do you infer from this?

After getting responses PT will further explain:

Characterstics 3:

Expansion and contraction of substances on heating and cooling.

Energy is used to change the state of substance only.

Characterstics 4:

By giving several examples like stretching of rubber.

Evaporation of water etc.

PT will explain 4^th characterstics:

Physical changes are reversible in nature.

Recapitulation:

PT will show a digital flip book to the students. She will provide some images to the students and ask them one by one to find out which characterstics of physical change suits this situation.
