The document contains a micro lesson plan presented by teacher trainee Vimla K on the topic of physical and chemical changes. The lesson begins with an introduction that engages students by relating changes to preparing lemon juice. The teacher then explains the difference between physical and chemical changes, providing examples such as water changing state through heating and cooling, and rust forming on iron. Throughout the lesson, the teacher uses techniques such as comparing and contrasting the two types of changes, asking questions to check understanding, and providing illustrations. At the end, the teacher summarizes the key differences between physical and chemical changes, and thanks the students.

Introduction.
change
Good morning students.
How are you all?
Today we will going to learn about a
physical and chemical change.
What is change?
We see various types of changes
everyday around us.
When you help your mother
preparing a glass of lemon juice for a
guest the water becomes sour and
also sweet if you add sugar or honey
in it.
Good morning madam.
Fine madam.
Students are carefully
listening.

Physical
change
This is a change.
Changes can be of two types:
1) Physical Change
2) Chemical Change
It is clear to you all.
Physical change
Before we learn about physical
Changes, we must know about
Physical properties.
Properties such as size, shape,
Color and state are known as
Physical change.
In a physical change the
Substance undergoes a change
in its physical properties.
Yes madam.
Students are
carefully listening
and are trying to
understand.
Clarity of
concept.

Physical
change
In general physical changes are
reversible.
For example:
When you heat bowl of water, the
water becomes steam. If you collect
the steam in a cold plate by holding
the plate over the steam ,you see
the vapour turning into water and
forming tiny droplets. Again if you
put the water in refrigerator it turns
into ice and when you take it out it
melts and becomes water again.
In all these physical changes, the
substance that is the water changes
in state.
Student listen
attentively.
Compare and
contrast.

Chemical
change
Chemical change
Chemical changes are those changes in
which a substance undergoes changes
that are generally irreversible.
These means that one a chemical
change has occurred it forms a
completely new substance with new
chemical and physical properties.
For Examples:
The mot common changes that we see
around us is rusting of iron . If we leave
an iron nail in a place full of moisture.
We see a brown color rust on it. The rust
is a new substance and its properties
are not same as the properties of iron.
Iron get attracted to magnets. But if you
collect some rust and bring near it ,will
it be attracted to the Magnet?
Students
listen silently.

Questions
NO.
Because there was a chemical
change in the iron and a new
substance is formed, which is rust.
Chemical reaction find widespread
use in and around us.
Useful material such as medicines,
plastics, nylons, detergents etc. are
synthesized after a chain of
chemical reaction.
What is physical change?
Student observe.
Substance
undergoes
change in its
physical
properties are
known as physical
change.

Concluding
statement
Give an example?
Give an example of chemical
change?
So today we studied about physical
and chemical change.
In physical change the substance
undergoes change in it physical
properties where as in chemical
change , the substance undergoes
change in chemical and physical
properties.
Physical change is reversible and
chemical change is irreversible
change.
Stretching of
rubber band.
Cooking of food,
rusting of iron.

In physical changes energy is neither
generated nor observed whereas in
chemical change energy is either
generated or observed.
Ok thank you rest of the things we will
see later.
