Special characteristics

of animals that protect themfrom danger.

special behaviour

of animals that protect themfrom danger.

The special characteristics and

behaviour of animals help toprotect them from danger.

3.1 animals have specific characteristics and

behaviour to protect themselves

Thick and hard skin

To prevent their enemies from injuring

Hard shell

Snails and tortoise retract their head

And legs into the shell when the are

Attacked by enemies

Hard scales

Pangolins and crocodiles have hard

scales To protect their bodiesfrom injuries

Spines

Raise the sharp spines when

the enemies

Advance towards them

Horns

Use their horn to attack enemies.

Sharp claws

To protect themselves and their

Young from the enemies- lion ,cat,

Bears, and eagle.

Spray black ink

Dark surrounding helps the animal not

to been seen by enemies

Can hurt and kill enemies-e.g..: scorpion,

centipede snake , bee.

Camouflage

Has body colour or patterns that that are

Similar to the surrounding

Pretend to dead

To trick their enemiese.g.: beetle

specific characteristics and

behavior of animals that protect

them from very hot and cold weather.

Hot weather Cold weather

Wrinkled Skin

Elephant ,hippopotamuses and buffaloes

Wallowing

Elephant, hippopotamuses and buffaloes

keep their body cool by wallowing in

mud holes

Humps

Camels store food and water in the form

Of fats in the humps on their back.

Thick Fur

From losing heat to cold surroundings.

Fat Layers Under The Skins

Penguins, seals, and whales have fat layers under

their skin to keep their bodies warm

1.3Appreciating the perfect placement

of the planet Earth in the

Solar System

Why certain planets

are not conducive

for living things.EFFECTThe Earth is

the only planet in the

Solar System that

has living things.

The nearer a planet to the Sun is,

the hotter is the surface of the planet .

The farther a planet from the Sun is,

the colder is the surface of the planet.

Do not have enough air and water.

Earth is the third planet from the Sun, it receives enough light

and heat from the Sun.

It is not too hot or too cold.

The atmosphere of the Earth contains air and there is water

on Earth.

Much nearer :

The temperature on the Earth would rise.

Water on Earth would evaporate.

No water and the temperature would be

very hot.

Much farther :The temperature on the Earth would drop.

Water would freeze into ice.

All living things would die.

1.4 Analysing That Technology Can Benefit Mankind If Used Wisely

Advantages of Technology Disadvantages of Technology

CommunicationEnable human to learn more about

things happening around the world

Transportation

Enable human to travel

far away places in shorter time

AgricultureMachines make it easier to plants

and harvest their crops

Construction

Roads, highways, bridges and

building is easier and faster to build

Environmental pollution from increaseIn waste materials

Environmental destruction result from

excessive usage of natural resources

Social problem

Bad effects on health result from

environmental pollution and excessive

use of chemicals
