NAME OF CONCEPT
: Renewable and non-renewable resource
OBJECTIVES :
Ø Pupil develops observation skills
Ø Identification of different type of renewable
and non-renewable resources
Ø Generalization about property of renewable and
non-renewable resources
Ø Pupil develops hypothesis predicting result
PHASE 1: DATA
CATEGORISATION
T
: What is the common property of petrol, kerosene and
wood?
S
: They are all fuels.
T :
Can you name some other fuels that we use in our daily life?
S
: Diesel, CNG, biogas, biomass, gober gas, cow
dung cake, LPG.
T
: Can you group them based on their similarity?
|
A
|
B
|
|
Biogas
Wood
Cow
dung cake
|
Petrol
CNG
LPG
|
PHASE 2: INTERPRETATION
OF DATA
T
: Now let us analyze the above mentioned
examples. How did you classify them?
S : Items in group A can be
produced at home. But in B can’t.
T
: Very good. Anything else?
S
: Items in group B are easy to handle.
T
: Yes. Are there any more
differences?
S
: Group A items are
easily available in nature and can be replaced once they are used.
T
: Absolutely right. Can you
name them?
S
: No teacher.
T
: They are renewable and
non-renewable resources. Non-renewable resources are those resources that can’t
be replaced once they are used up. Renewable resources are those resources that
can be replaced as they are used up.
PHASE 3:
APPLICATION TO GENERALISATION
T
: Now I will give
you some examples. Identify them-sunlight
S
: Renewable.
T
: Right. Why is it
renewable?
S
: Because it can be
replaced once they are used up.
T
: Yes. Then coal.
S
:
Non-renewable.
T
: Very good.
Air
S
: Renewable.
T
: Yes. So renewable resources are those
resources that can be replaced as they are used. Non-renewable resources
are those resources that can’t be replaces once they are used up.
