CONCEPTS:METHOD OF SEPARATION
-- Handpicking :- This is method of separation of substances with help of
hand.
-- This method is used when size of materials is large & also
-- The quality is limited also.
-- SEIVING:-This is method of Separation o substances from mixture with the
help of sieve.
-- This method is used when size of substance is small &
-- components of mixture have different sizes
PREVIOUS KNOWLEDGE:--Day today activities like separation of tea powder from Tea, removal of
stone or husk from slice.
-- The student should know to separate different substances.
INTRUCTIONAL MATERIALS:SET INDUCTION:ACTIVITY -I :-Rice ,husk, wheat flour, stones, Masoordal, Groundnuts -worksheet-I
DEVELOPMENT:ACTIVITY -II :- Sand, stones, onion, potato, Dal, wheat flour, Groundnut,
Grams. worksheet-II
ACTIVITY -III :- Wheat flour,
worksheet-III
Small stones, Rava, Rice, Sand & stones
SEQUENTIAL TEACHING LEANING
EXPECTED BEHAVIOURAL
ACTIVITIES
OUTCOME
SET INDUCTION :Teacher greets the students
Students also greets teacher
Tr,. :- Good Morning student
ss:- Good Morning teacher
Activity -I :Material required :- Rice, Husk, Wheat flour,
stones, Groundnuts & its coverings.
-- Teacher makes pair of students as one
group
-- Teacher gives following instruction to
students
I will give mixture to each group . Do Not
eat the substances given to you from this
mixture.
I want each group to have individual
substances.
-- Teacher gives worksheet to each group.
-- Observe given mixture substances is
useful or not.
--Teacher ask following questions based on
activity
Tr:- Group I :- Which mixture was given to
ss:- Rice & husk
you?
Tr:- What you have done with this
ss:- Separation
mixture?
Tr:, which all thing you have separated?
ss:- Husk from Rice
Tr:- Which substance is useful to us?
ss:- Rice
Tr:- Why there is need of separation of
ss:- husk is an unwanted thing
husk from rice?
Tr:- So you have done separation for
ss:- Wheat flour & stones
removing unwanted substance from mixture
.
Tr:- Group II :- Which mixture was given to
ss:- separation
you ?
Tr:- What you have done with this mixture?
ss:- stones from wheat flour
Tr:- what substance you have separated?
ss:-
Tr:- why there is need for separation of
ss:- stones is an unwanted thing
stones from wheat flour?
Tr:- so why you have done separation?
ss:- To remove unwanted things
from useful once.
Tr:- Group III:- which mixture was given to
ss:- Ground nut and their
you?
coverings
Tr:- what you have done with this mixture
ss:- separation
Tr:- which is useful components in your
ss:- Groundnut
mixture?
Tr:- covering is non useful component?
This activity shown that
you have separated mixtures into
individuals
components based on whether the
substances are useful or not and
To remove unwanted things from useful
once.
STATEMENT OF TOPIC:so today in this class we are going to learn
about “ METHODS OF SEPARATION”
(Tr. write on C.B.)
DEVELOPMENT OF LESSON :ACTIVITY-II:Material required:- Sand, stones,Dal,.
wheatflour,Groundnut,Grams,Onion,Potato.
-Teacher divides class & make pair student
as I group
- Teacher gives following instructing to
students
I will give mixture to each of group you
have to
seperated this substances
-Teacher give each packet of mixture to
each group
- Teacher gives one worksheet to each
students separate the mixture
group
into individual components
Teacher ask following question to students.
Tr:- What you have done with mixture?
ss:- separation
Tr:- How you have done separation?
ss:- with the help of hand
Tr:- what is the size of these substances?
ss:- Big
Tr:- Is the amount of mixture is large or
ss:- small
small?
Tr:- Group -II what is given to you?
ss:- Mixture of sand & stones
Tr:- what you have done with mixture ?
ss:- separation
Tr:- which substances you have separated ? ss:-stones from sand
Tr:- Is amount of mixture is large small?
ss:-small
Tr:- How you have done separation ?
ss:- with the help of hand
Tr:- Group -III:- what is given to you?
ss:- mixture of potato & onion.
Tr:- what you have done with mixture?
ss:- separation
Tr:- which substance you have separated?
ss:- potato from onion
Tr:- what is the size of these substances?
ss:- big
Tr:- How you have done separation?
ss:- with the help of hand.
Tr:- In all above mixtures you have seen
that these can be easily separated by hand
& all these substances are bigger in size &
smaller in quality?
:. This activity shows that
- The method of separation of substances
with help of hand is called as hand picking.
- This method is used when size of
materials larger or big.
- This method is used if quantity is small.
-Tr:- If you have to separate a whole bag of ss:- No
wheat flour mixed with stones can you use
handpicking method?
Tr:- when quantity is large we can use
other method.
Tr:- you will require hours to separate
stones from wheat flour you have top adopt
certain other way for separation.
ACTIVITY-III:Material required :- different types of sieve,
wheat flour, small stones, Rava, Rice, Sand
& Stones.
-- Teacher makes pair of student as one
group
- Teacher gives following instructions to
students listen to instructions
students observe the mixture carefully &
teacher
-Teachers gives worksheets of each group
you have to put tick mark in correct box.
- Teacher tells one by one group to come
Student select appropriate sieve
forward& separate mixture.
require for separation of their
mixture.
- Teachers tells to note down which sieve
they are using& mark on worksheet.
- Teachers asks following Questions based
on activity.
Tr:- what is given to you?
ss:- Mixture of wheat flour &
stones.
Tr:- How you have separated this mixture?
ss;- with the help of sieve.
Tr:- what is the size of this substances?
ss;- small
Tr:- which sieve you have used for
ss;- sieve. A
separation?
Tr:- why you have not used for other 2
ss;- size of pores of sieve B was
sieve ?
big.
Tr:- what will happen if you use other
ss;- Mixture will not get
sieve?
separated
Tr:- why mixture will not get separated?
ss;- size of pores Big
Teacher ask similar Questions as above to
Group II & Group III
Tr:- So we can say that method of
separation with the help of sieve is called as
sieving.
If quantity is large & size of substances is
small this effective method of separation.
This activity shown that
-The method of separation with help of
sieve is called as sieving.
-This is used for separation when
components have different size.
Tr:- Let us summaries what we have learnt
today. Teacher uses concept map &
summaries what we have learnt today.
