Facts:
*Material system made up of two or more
different substances mixed, and are not
combined chemically are called mixtures.
*Saline water is an example for mixture.
*Black ink is a combination of many
colours.
*Ammonia is manufactured by combining
nitrogen and hydrogen.
Concepts: *Separation is a method to
achieve any mass transfer phenomenon
that converts a mixture of substance into
two or more distinct products.
*Magnetic process is a process used to
separate the magnetic substance from a
mixture using magnetic property of the
substance.
*Distillation is the process used in
separating mixtures having a substantial
difference between the boiling points of
the two component liquids.
*Fractional distillation is the process of
separation of a mixture of completely
miscible liquids having a small difference
in their boiling point.
*Filtration is the process of separating the
components of mixture on the basis of the
size of the particles.
* Evaporation is a type of vaporization
of a liquid that occurs from the surface
of a liquid into a gaseous phase
Learning outcomes
The pupil;
1. Recognizes the concept separation of
mixtures.
2. Recalls the concept separation of
mixtures.
3. Explains the concept separation.
4. Uses the concept separation in new
unfamiliar situations.
5. Focuses the idea; different separation
techniques for the separation of
mixtures.s
6. Judges the concept separation of
mixtures and its separation techniques.
7. Suggests examples for separation of
mixtures.
Pre-requisites
The pupil already knows about mixtures
and its separations.
Teaching-learning resources:
Chart (concept mapping-separation
techniques), pictures.
Classroom interaction procedure
Introduction: Teacher started the class by
Introducing day today life problems related to
Mixtures and separation by showing a picture
Expected
pupil responses
Students
observing the
picture.
Why is the paddy winnowed after
The reaped stalk bundles are
Threshed?
Then teacher posed a thought
When the bundiles
are threshed there
will be plenty of
chaff mixed with
paddy.
Provoking question to the class;
When paddy is de-husked what
By winnowing
We get is rice mixed with bran;
How are these separated?
Very good; what this material
System called?
Yes these are called mixtures.
mixtures
Can you now clear it out
What the term mixture
Material system
made up of two or
more different
substances mixed
together.
Meant for?
Very good; Many of the
Substances which we use
In our daily life are found
In the form of mixtures.
Does all they can be
Separated by winnowing?
Yes; good, you are right.
There are different
Separation techniques
No;
There are different
separation.
Can you name?
Yes; evaporation
,filteration,vapou
risation.
Good; shall we learn different
Separation techniques in a
yes
new way.
Teacher then presented a
Planned concept mapping
Including different separation
techniques in it. Teacher then
Explains;
This called a concept mapping
Method of study. This helps
You to learn effectively by
Focusing to the main concepts
And sub concepts using linking
Lines and connecting words.
students listening
to the teacher.
Students
