2. “MONEY IS NOT THE POWER TO WIN.
KNOWLEDGE IS THE POWER TO WIN.”
Money is not the way to win. As you
know, from money we cannot succeed in
a life. Do you heard the proverb
“Knowledge is power”? This means you
should read books. For that the SREE
Companies is providing book called SREE
SCIENCE KNOWLEDGE for 5th standard.

19. ENOUGH FOR BORING
Is it very boring when you always
study. So for that R. SREERAJ MENON is
presenting a video clip on the topic
‘Resources’.

21. OOM… A STORY
Here is our Rosy to tell a story about
resources. This is a story of Achu that
he understand the importance of
resources. Let us read the story now.

22. THE WAY ACHU UNDERSTAND THE
IMPORTANCE OF RESOURCE
Achu is brushing and the water goes through the tap. He is wasting water. When he, Pinky, and
Smiley bus going to their house by the narrow way he throw the water in the bottle. He didn’t
switch of fans & the television and go to play.
One day Pinky asked him “ why are you wasting resources?”. His answer was “don’t worry! We
have enough of them”.
But that night had a bad dream. When he was bathing there is no water, when he go to school
there was no food. When the is doing the homework there was no electricity and candle has finish
up. He suddenly wake up and thought we should not save our resources.
The next day, Pinky & Smiley were waiting for school bus. Neel was upset at that time. Pinky asked
“ Why are you sad? Cheer up!”
In the bus he said the bad dream happened yesterday. Smiley said that it may be happen, when all
the resources are finished….. And we will be left nothing to use. When the Smiley is saying she
interrupt and asked a question “How will I see TV then? Smiley said you can watch TV an hour.
Then he was back to speech. He said so we need to save them for feature use also.
The next day Achu give the left water in bottle to plants. And when the mother give him food he ate
full & he is now saving electricity also. From that day Achu started to save resources.
This is how Achu understand the importance of the resource.

24. AN INTRODUCTION
You must have seen plants being
grown in gardens and in fields.
Why do people grow them? This
is because we get lot of things
from plants.
Growing plants is important as
our life depends largely on
them.

25. GROWING PLANTS
FROM SEED
If you eat an apple or an orange
you will find seeds inside. New
plants can grow from these
seeds.

26. PARTS OF A SEED
Seed leaves or cotyledons
store food for the baby
plant.
An outer covering called the
seed coat protects the baby
plant inside.

27. GROWING PLANTS
FROM SEED
Not all seeds grow into new plants.
Some plants are eaten up by birds
and insects; some get destroyed by
rain or wind; while some seeds do
not get sufficient air, water or
warmth to grow. If the seed survives
and gets right amount of water, air,
warmth (from the sun), it will produce
a baby plant or seedling

28. GERMINATION
The process by which a seed
produces a baby plant or
seedling is called
germination.
One Minute Please
Do you know that beans grow
from seeds.

29. GERMINATION
i). The seed gets water air and warmth.
ii). The seed coat breaks and the baby plant emerges.
iii). The baby plant develops roots and a shoot.
iv). As the plant grows in size it develops leaves. The
cotyledons shrink and appear

30. THE IMPORTANCE OF
SOIL
During the early stages of germination, the seedling
gets the food required for its growth from the
cotyledons. Can you tell from where the seedling get
its food from after the food stored in the cotyledons
has been used up? The reply is soil. The seedling
absorbs water and nutrients from soil with the help of
its roots. it build up with leaves and grow into a plant.
Also, air (which is necessary for germination)
reaches the seed through pores in the soil. This is
why soil is so important for plant growth.

31. IF PLANTS LIVE TOGETHER
IN ONE AREA WHAT WILL
OCCUR?
If plants live together in one place it is
dangerous for that plants because
they will struggle for air, water,
sunlight, nutrients and space to
grow. Many of them would die. In
nature, many plants scatter their
seeds in order to ensure that they do
not grow too close to one another.

32. DISPERSAL
The process by which the seeds
are scattered away from the
mother plant is called
dispersal.
Nature has its own way of
dispersal of seeds.

33. DISPERSAL BY
WIND
Seeds of certain plants are very
light and have wings or hair on
them. These seeds are easily
carried away by wind.

34. One Minute Please
Dandelion seeds have hair that act like
a parachute. Wind carries these seeds
far away from the parent plant. The fluff
around the cotton seed helps it to float
away with wind.

35. DISPERSAL BY
ANIMALS
Animals and human beings eat
some fruits and throw away the
seeds, which grow into new
plants. Certain seeds have
hooks, stiff hair, or spines,
which help them in dispersal.

36. One Minute Please
Squirrels bury seeds and nuts
for eating them during winter.
Sometimes squirrels forget
where they had buried their
seeds. These seeds often
germinate and grow into new
plant.
One Minute Please
Some seeds have spines or
hooks. These seeds stick to the
bodies of animal and birds and
are carried away from the parent
plant. Birds and animals also eat
fruits. Seed pass through their
digestive system undigested and
are dispersed to other areas.

37. DISPERSAL BY WATER
Seeds of some plants such as
lotus and coconut are spongy or
have a fibrous covering, which
helps them to float on water.
Water transports these seeds
from one place to another.

38. One Minute Please
Coconuts can travel several
thousand kilometers across
oceans. The coconut palms on
the South Sea Islands grew from
coconuts carried by there by
ocean currents.

39. DISPERSAL BY
EXPLOSION
Fruits of certain plant such as
poppy, pea and bean burst open
when they are ripe, scattering
the seeds in all directions. This
mechanism of seed dispersal is
called explosion

40. One Minute Please
When the seeds of the pea plant are
ripe, the pod bursts open. The peas
are scattered away from the plant.

41. ROOTS THAT CAN
GROW INTO NEW
PLANTS
Carrot, radish, turnip and
beetroot are some of the
examples whose roots can grow
into new plants

42. STEM THAT CAN GROW
INTO NEW PLANTS
Potato and onion
are stems that
can grow into
new plants.
One Minute Please
Onion is a special kind of stem. It will
grow leaves if you plant one in the
ground.

43. GROWING PLANTS
FROM LEAVES
Young Plants
arise the
edges of
Bryophyllum
leaves.
One Minute Please
Do you know about J.C Bose? He is an
Indian scientist who proved through
experiments that plants have life. He also
invented several instruments to study
about plants. The most wonderful
instrument was the Crescograph, used to
measure the rate of growth plant.

44. One Minute Please
Venus fly- trap has two lobes to eat food.
Don’t you understand? This means this
is a carnivore plant. When any animal
come and get inside the lobe, the lobe
suddenly close and the plant get food.
Complete
plants can be
grown from
these leaves
if they are
placed in
moist soil.

45. GROWING PLANTS
FROM SPORE
Some plants do not have seeds.
They grow with the help of tiny
structures called spore. Fungi
and ferns are examples of such
as plants. Mushrooms and other
fungi, and ferns reproduce with
the help of spores.

46. Puffball mushroom releasing spores.

47. AGRICULTURE
Imagine that you have a small
kitchen garden where you grow
fruits and vegetables. The fruits
and vegetables may be enough
for you and your family, but can
you grow enough fruit in kitchen
garden to feed thousand
people? No.

48. AGRICULTURE
In order to feed the entire
population, plants are grown on
a large scale.
The practice of growing plants on
a large scale is called
agriculture.

49. AGRICULTURE-CROPS
The plants that are grown in large
quantities in a particular area or
region at a particular season
are called crops.

50. STAGES OF
AGRICULTURE
(1) Field is ploughed (2) Manure is added to the
soil.
(3) Seeds are sown (We are very sorry to you because there is no
image for “Seeds are sown.”)

51. STAGES OF
AGRICULTURE
(4) Fields are
irrigated ( “How this
field is irrigated?”
look at side.)
One Minute Please
Drawing Water from a Canal
A farmer arranges siphons to draw
water from an irrigation canal and send
it down furrows in his field. The furrows
are narrow, relatively shallow trenches
designed to carry water as far down a
crop row as possible. One
disadvantage of the furrow method of
irrigation is that plants nearer the water
source may receive much more water
than those further away.

52. STAGES OF
AGRICULTURE
(5) Pesticides are sprayed
to protect crops.
One Minute Please
(An important case)
People in Tamil Nadu are using a
pesticide called Endosulfan to protect the
crops. Do you know that Endosulfan is
very dangerous to us. In Kasargode the
farms has sprayed Endosulfan and they
are now patients in hospital because of
the acid in Endosulfan. Some have the
heads big and other all are small, some
have one leg or one arm small others are
big. This accident took place on 2010th
before October. For your safety I am
reporting that it is not good to buy and eat
fruits from Tamil Nadu & Kasargode.

53. STAGES OF
AGRICULTURE
(6) The crops are harvested.

54. STAGES OF
AGRICULTURE
i). The field is ploughed.
ii). Manure is added to the soil.
iii). Seeds are sown.
iv). The crops are watered or
irrigated.
v). Pesticides are sprayed to
protect the crops.
vi). Crops are harvested.

55. THE TWO TYPES OF
CROPS DEPENDING ON
THE SEASON
A particular crop may grow well
in one season and may not grow
that well in another season.
This is why farmers grow
different crops in different
seasons. There are two types of
crops depending on the changes
of the season. They are Kharif
Crops & Rabi Crops.

56. KHARIF CROPS
Crops grown from June to October
are known as Kharif Crops. These
crops depend largely on the
monsoon rains. Examples rice and
maize.
Failed Maize Crop
Rice

57. RABI CROPS
Crops grow from November to
April are called Rabi Crops.
These crops do not depend on
monsoon rains. Examples are
wheat, beans and legumes
Soya beans

74. ENOUGH FOR BORING
Is it very boring when you always
study. So for that R. SREERAJ MENON
is presenting a video clip on the topic
‘Resources’.

76. OOM… A STORY
Here is our favourite Rosy to tell us a
story about plants.

77. THE USE OF TREE
Manu and Bolu are great friends. Once they travel
together to Sikhanpur. In the way they feel very
thirsty and hungry. They sat down in the tree shade.
At that time Bolu looked at the tree. Bolu asked to
Manu: “there is no fruits, no flowers in this tree, then
why this tree is living? The reply of Manu was “don’t
look the deficiency of tree. You said is correct. I
accepted. But this tree is giving shade to us.” Thus,
Bolu understand that don’t look the deficiency, look
how tree is useful.

78. BOAT
WATER
SO WE ARE GOING TO STUDY ABOUT:

79. AN INTRODUCTION
Matter is any substance that has mass
and occupies space. You have learnt in
your previous class that there are three
states of matter.
Can you name the 3 states of matter?
_____________________________
All matter is made up of small parts called
molecules. Molecules are made up of
atoms

80. PARTICLE ARRANGEMENT IN
SOLID
In solids, the particles are tightly packed
in a rigid pattern and so cannot move
away from one place to another.
Particle arrangement is solid

81. PARTICLE ARRANGEMENT IN
LIQUID
In liquids, the particles are not as tightly
pack in solids; so they can move and
slide over each other. This makes
liquids flow and take the shape of the
contained they are poured in.
Particle arrangement in liquids

82. PARTICLE ARRANGEMENT
IN GASES
In gases, the particles are far apart from
each other and can move freely. So,
gases can flow easily and take up all
the available space.
Particle arrangement in gases.

83. CHANGE OF STATE
You already know that matter can
change from one state to another, for
example, water (liquid) can become
steam (gas), and ice (solid) can melt
and become water (liquid). Let us
know the changes in the terms of the
movements in tiny particles.

84. EVAPORATION
When water gets heated, it evaporates,
or, it changes into water vapour. This
happens because on heating the
particles of water start vibrating or
moving faster. Finally, they break free
from their existing arrangement and
escape into the air. They become gas,
where the particles can move much
more freely.

85. CONDENSATION
Steam condenses to form water again. When the
freely flowing particles of steam touch a cold
surface, cooling happens. Cooling a substance
slows down the movement of this particles.
The particles thus become less free to move
and become loosely packed to change from gas
to water.

86. MELTING
Ice is a solid. The water particles in solid ice are
rigidly packed to give a fixed shape. When ice
is taken out of the refrigerator, it melts
gradually. This is because in a warm place, the
water particles in ice start vibrating faster and
finally break away from the rigid pattern. They
become loosely packed as in a liquid and form
water.

87. FREEZING
In freezing, when the water is cooled, its
particles start slowing down and pack
themselves into a rigid shape, thus forming
solid ice.
One Minute Please
You should not keep the
refrigerator door open for a long
time or open the door very often.
This lets the cold air flow out of
the refrigerator. Save electricity by
reducing the amount of time the
door is open!

88. EXPANSION
Heating a substance can make it expand. When a
substance is heated, the particles start vibrating
rapidly. Thus, each particle takes up more
space due to their increased movement, so, the
substance expands. The increase in size of
matter on heating is called expansion. This
explains why a tight metal lid of a jar can be
opened when dipped in hot water. The heat of
the water causes the lid to expand a little &
open out easily.

89. CONTRACTION
Cooling a substance can make it expand. When a
material is cooled, the particles slow down. They
take less space as their movement has decreased.
This is why the material contracts. So, cooling a
substance can make it contract. The decrease in
size of matter on cooling is called contraction. It
is due to the effects of heating and cooling that
electric cables hang loosely from poles in
summer and do not appear loose in winter
ONE MINUTE PLEASE
Do you know that ice occupies
more space than water.
in winter.

90. REVISION
