2.1Survival of Animal
Species
Examples animals that take care of their eggs and youngs.
how animals take care of their eggs and youngs.
Why animals take care of their eggs and youngs?
Bird - Eggs with shell coveringFrog - Eggs are thick, slimy and having bad smellSpider - kept in a bag underneath its bodyFish - keep their young in their mouthsSnake, Tiger - attack in order to protect their eggs Turtle - hide their eggsKangaroo - carry their young in their pouches Elephant - stay in herds
2.3Importance
Shortage of food resource
Animals and plants species may face extinction.
Bird, Frog, Spider, Fish, Snake,turtle, Kangaroo, Elephant

3.1 Food Chain
Animals and the food they eat
Classify animals into herbivore, carnivore
and omnivore.Producer Consumer Construct food chain
Green plant obtain energy from
the sun to make food. Green
Plant as a producer
Herbivore :Animals that eat plants only.
e.g.: cow, goat, deer
Carnivore:Animals that eat other animals.
e.g.: tiger, lion
Omnivore:Animals that eat plants and
other animals
Animals that eat plantor other animals
are called consumers.
The food relationshipamong living things
can be shown bya food chain.
To construct food chain It must start
with plant as a producer.
In a food chainthe arrow
means ‘eaten by’
All living things need food to survive.
Green plant can make theirown food. However
animals cannot make their own make
their own food.
3.2 Synthesizing food chainto construct food web.
Food web
What will happenIf there is a change in population of a certainspecies in a food web
Foodweb of different
habitats
What will happento a certain species
of animals if theyeat only one type
of food
Paddy field
garden
A change in the populationof a certain species
will effect the Population of other species
They will face difficultyto survive – if the
source of food runs out

INVESTIGATING FORCE AND ENERGY
ENERGY 1.1 The Uses of Energy
Why energy is needed?
- by living things to carry out life processes. Ex : moving, breathing, growing
The Sources of Energy
Sun
- main source of energy- produces light and heat
Food
- food contains stored energy
Wind
- Moving air- Used to pump water, drive small sawmills
- to move, boil, melt, or bounce non-living things
FuelBatteries
- coal, petroleum, natural gas
- device that generates electrical energy from chemical energy
Water
- moving or falling water produce energy
INVESTIGATING FORCE AND ENERGY
ENERGY 1.2 Energy can be transformed from one form to another
Form of energySound energy
Heat energy
Light energy Electrical energy Kinetic energy
Chemical energy
Potential energy
Energy can betransformed
a) lighting a candle Chemical energy → light energy + heat energy
b) Kicking a ball Chemical energy → kinetic energy
Example of appliance that make use of energy transform
a) Electric iron Electrical energy → heat energy
b) Radio Electrical energy → sound energy
c) Television Electrical energy → light energy + sound energy
INVESTIGATING FORCE AND ENERGY
ENERGY
1.3 Renewable and Non-renewable Energy
Renewable energy
Energy that cannot be replaced
Resources –solar, wind,biomass fuel,water
Non-renewable energy
Energy that be replenished when it is used up
Resources –natural gas,petroleum,coal
Why use energy wiselyHow to use energy
Some energyresources cannotbe replenishedwhen used up
To savecost
Avoid wastage
Reducepollution
Turn off thetelevision whenno onewatching it
Switch off thelights beforegoing to leavethe room

Precautions
Differences
The bulb in the parallel circuit is brighter than the bulb in the series circuit
Danger of mishandling electrical appliances
Fire Burn
Electric shock Electrocution
Safety precautions to be taken when using
appliances
Do not touch electrical appliances with wet hand
Do not repair electrical appliances on your own
Light
Can be reflected
How ?
Uses of reflection
Side mirror of a car
Periscope Kaleidoscope
Travel in a straight line
How shadow is formed
When light is completely or partially blocked by an opaque
object
The light that falls on objects ‘bounces off’ the objects and comes to your eyes

How to measure temperature using the correct technique
The effects of heat on matter
Matter expands when heated
Matter contracts when cooled
