2.4 Life processes plants undergoplants respond to stimuli.water, sunlight, touch, gravity.

why plants need to reproduceto ensure the survival of the species.

various ways plants reproducethroughseeds, spores, suckers, stem cutting, leaves, underground stem.

what will happen to the world if plants do not reproduce.

no food supply.

Special characteristics of animals that protect them from danger.special behaviour of animals that protect them from danger. The special characteristics and behaviour of animals help to protect them from danger.3.1 animals have specific characteristics and behaviour to protect themselvesThick and hard skinTo prevent their enemies from injuringHard shellSnails and tortoise retract their headAnd legs into the shell when the areAttacked by enemiesHard scalesPangolins and crocodiles have hard scales To protect their bodies from injuriesSpinesRaise the sharp spines when the enemies Advance towards themHorns Use their horn to attack enemies.Sharp clawsTo protect themselves and their Young from the enemies- lion ,cat,Bears, and eagle.Spray black inkDark surrounding helps the animal not to been seen by enemies e.g: octopus, squidPoisonous sting or fangsCan hurt and kill enemies-e.g..: scorpion, centipede snake , bee.CamouflageHas body colour or patterns that that are Similar to the surroundingPretend to deadTo trick their enemies e.g.: beetle

3.2/3.3 Animals have specific characteristics and behaviour to protect themselves from extreme weather and survive

how specific characteristics and behavior of animals help to protect them from very hot or cold weather.specific characteristics and behavior of animals that protect them from very hot and cold weather.Hot weatherCold weatherWrinkled SkinElephant ,hippopotamuses and buffaloes lose body heat through wrinkled skinsWallowingElephant, hippopotamuses and buffaloes keep their body cool by wallowing in mud holesHumpsCamels store food and water in the formOf fats in the humps on their back.Thick FurPolar bears have thick fur to prevent the body From losing heat to cold surroundings.Fat Layers Under The SkinsPenguins, seals, and whales have fat layers under their skin to keep their bodies warmSmall EarsSeals and Walruses have small ears to prevent Heat loss from their bodies.HibernatePolar bears hibernates during extreme cold Weather

3.4 Plants havespecific characteristics to protectthemselves from enemyThe specific characteristics of plants that protect them from enemies How the specificcharacteristics of plants help to protect them from enemies.

characteristics that protect plants.

Have thorns

poisonous

Have fine hairs Produces latex

Close leaflets when touch

3.5 Plants have specific characteristics to protect themselves from dry region and strong wind

strong wind

dry region

Eg : cactus

.

Long roots to absorb waterSucculent stem can store waterThorn can can prevent the excessive loss of water

Eg: Coconut tree, bamboo tree, mangrove tree

Have stems that bend easily Have buttress rootsHave separated leavesNeedle- shaped leaves

INVESTIGATING FORCE AND ENERGY

Volume MEASUREMENT1.1 Length1.2 Area1.5 Mass1.6 Time1.7 Standard units1.3 Solid1.4 Liquid

1.1LengthTerminology- The distance between two points/place/positionWays to measureMeasuring tape CubitArm spanStringRulerStandard ToolsMeasuring tape Ruler UnitmmcmmkmCorrect technique- The eye must be directly above the end of object

1.2 Area- Area is the amount of Space taken up by the surface of an object. Terminology- Using square card with a sides of 1 centimetreStandard unit- Square millimetre (mm2)- Square centimetre (cm2)- Square metre (m2)- Square kilometre (km2)- Using formulaArea = length X width

1cm 1cmDifferent ways to measure area

2cm 4cm = 4cm X 2 cm = 8cm2

3cm 3cm

1.5 Mass

Terminology- Amount of matter in an object

ToolsElectronic balanceSimple balanceBeam balanceKitchen scaleBathroom scaleLever balance

Correct technique

1.6 Time

Terminology- Duration between two event

Way to measure- Sundial , sand clock , candle clockProcess that repeats uniformly can be used to measure time Swinging pendulum Pulse rate candlewater drippingChanging day and night

Tool

Standard unit- Second , minute , hour- Digital clock , watch , wrist watch , clock

Old clock

Events can be used measuring time

1.7 The Importance of Standard Units- for accuracy and consistency- easy to communicate and understanding
