Animal cell: nucleus, cell membrane, cytoplasm
Plant cell: nucleus, cell membrane, cytoplasm, cell wall, chloroplast

Nucleus: control all activities, contains information, one generation to another
Cell membrane: controls movement, materials/substances, moving in and out of cell, semi-permeable
Cytoplasm: jelly-like substance, contains other cell parts
Cell wall: protects, holds
Chloroplast: green, chlorophyll, photosynthesis
Air and living things
http://www.sclerodermasociety.co.uk/userfiles/lungs.jpg

Air: mixture of gases

Plants and air: stomata, life processes, oxygen, carbon dioxide, respiration, photosynthesis

Fish and air: gills, gill filament, dissolved oxygen, carbon dioxide

Respiratory system: nose, windpipe, lungs, air sacs, oxygen, blood, other part of body, carbon dioxide, water vapour

Circulatory system: heart, blood, blood vessels, pump
-          Heart receives OXYGENATED/OXYGEN-RICH blood from lungs and pumps to rest of the body.
-          Heart receives OXYGEN POOR blood from rest of the body and pumps to lungs to be expelled.
WHAT IS THE LINK BETWEEN THE RESPIRATORY AND CIRCULATORY SYSTEM??
http://www.bbc.co.uk/schools/gcsebitesize/science/images/addgateway_plant_stem.gifPlant transport system

Food-carrying tubes: transport, food, leaves, all parts of the plant
Water-carrying tubes: transport, water, mineral salts, roots, all part of the plant

Root: anchor, ground, store food, absorb water and mineral salts
Stem: hold, upright, spread out leaves, store food
Leaf: make food, photosynthesis, exchange of gases, stomata
Flower: reproduce, pollination
Fruit: protect seeds
Electrical systems
http://www.villageofschillerpark.com/assets/1/news/Light_Bulb_Image.gif
Sources of electricity: Power station, batteries, renewable, non-renewable

Electrical circuits: switch, wire, bulb, metal casing, metal tip, battery, positive/negative terminal, open/closed circuit, complete, bulbs in series/parallel, batteries in series/parallel, brightness

Factors affecting brightness of a bulb:
-          Number of batteries
-          Arrangement of batteries (series/parallel)
-          Number of bulbs

Conductors: allow electricity to pass through, metal
Insulators: do not allow electricity to pass through, non-metals, protect from electric shock/ electrocuted
P4 CYCLES
Life cycle of plants and animals
http://www.fi.edu/fellows/fellow9/jun99/images/lifecycle.jpg
Ensures survival, prevents extinction

Animal life cycle:
3 stages – egg, young/nymph, adult
4 stages – egg, larva (moults), pupa, adult

Plant life cycle: seed, seedling/young plant, adult plant
seed-germinationGermination – suitable conditions, air, water, warmth, seed leaf (stored food), seedling





Growing from other plant parts:
-          Root (carrot, radish)
-          Underground stem (onion, potato, ginger)
-          Leaf (begonia)
P4 ENERGY
http://www.give2thetroops.org/images/heat_injury.jpgHeat


Sources of heat: sun, burning fuel, hair dryer

Heat: amount of thermal energy
Temperature: how hot/cold object is

To measure heat: thermometer, data logger

How heat if transferred: from HOTTER to COOLER object, gain heat, lose heat
Heat gain à object EXPAND, ice MELT, water EVAPORATES
Heat lost à object CONTRACT, water FREEZES, water vapour CONDENSES

Conductors: pass through, good, bad
Light

Energy: the ability to do work

Sources of light
Natural light: sunlight
Artificial light: torchlight, like bulbs

Properties:
-          Light travels in a straight line
-          Allows us to see when it reflects off the object and into our eyes

Shadow: formed when object blocks light path
Changing distance between light source and object:
-          Object CLOSER to torch, shadow BIGGER
-          Object FURTHER from touch, shadow SMALLER

Changing position of light source à shadow can change shape

Transparency:
Transparent – light can pass through
Translucent – partially
Opaque – cannot pass through
(the LIGHTER the shadow, the MORE light has passed through)

Materials
http://celebrateanddecorate.com/wp-content/uploads/2012/05/wine-glass.jpg

Living things, non-living things

Properties of different materials: suitable
-          Float/sink
-          Flexibility
-          Strength
-          hardness
Body systems
http://www.go-symmetry.com/images/HumanBody.jpg
Body systems: work together, 2 or more parts, energy, move, take in air

Organ + organ = organ system

Respiratory system:
Mouth, nose, windpipe, lungs, exchange of gases, oxygen, remove carbon dioxide

Circulatory system:
Heart, blood, blood vessels, nutrients, oxygen, carries waste and carbon dioxide AWAY from all parts of body


Skeletal system:
Bones, work together, protect, hold up body, give shape

Muscular system:
Muscles, allow movement

Digestive system:
Teeth, tongue, mouth, saliva, gullet, stomach, small and large intestines, anus, break down, small pieces, digestion, digestive juices, absorbed

HOW DO DIFFERENT SYSTEMS WORK TOGETHER FOR OUR BODY TO FUNCTION WELL??
Magnets
http://ed101.bu.edu/StudentDoc/current/ED101fa10/kyliherz/Images/magnetalone.jpg
Properties:
-          Attract magnetic materials
-          Force strongest at poles
-          Opposite poles attract
-          Like poles repel
-          Magnet aligns at N-S direction when allowed to turn freely

Magnetic materials: iron, steel, nickel, cobalt
Non-magnetic materials: copper, silver, gold, aluminium, lead, rubber, wood, plastic, glass

Making magnets: electricity, electromagnet, stroke
‘Stroke’ method: same direction, iron nail, attract, iron filiings, number of times
Electrical method: coil, electric wire, iron nail, number of times

Using magnets: magnetic strip, store information, make images/sounds, compass
