Mind map year 4

  1. 1. 1.1 Understanding that humans have basic needs Give energy To breathe Grow Stay healthy Food Air Basic Needs Of Human Water Shelter Drinks Grow To protect from • danger Stay healthy • extreme weather • sun & rain
  2. 2. 1.2 Understanding that animals have basic needs Give energy To breathe Grow Stay healthy Food Air Types : Basic Needs • holes Of Animals • cave • nest • beehive Water Shelter Drinks Grow To protect from • danger Stay healthy • extreme weather • sun & rain
  3. 3. 1.3 Understanding that plants have basic needs Plants Have Basic Needs Air Water Sunlight With : Without : • grow healthy • wilted • grow well • Turn yellow • not wilted • Die
  4. 4. 2.1 Analysing life processes that humans undergo Inhale – take in air Nose/Mouth Wind-pipe Lungs Exhale – give out air Organs Purpose : • avoid danger Breathing Rate of breath • avoid getting hurt Number of chest movement • avoid getting injured In a period of time • to survive Respond To Analysing Life Processes That Human Undergo Reproduce Stimuli A process to produce Organs Excrete Defecate Their young or offspring Eyes - Sight Nose - Smell Lungs Faeces ( Carbon dioxide Tongue - Taste + water vapour ) Ears - Sound Kidney ( urine + mineral salt ) Skin - Touch Skin ( Sweat + mineral salt )
  5. 5. 2.2 Being aware that certain behaviour can disturb life processes Behaviour That Can Disturb Life Processes Smoking Drinking Alcohol Taking Drug Effects • Lung cancer Effects • Coughing • Delay respond to stimuli • Lose ability to walk in straight line • Can cause accidents How to avoid Participate in a campaign Discourage among their peers
  6. 6. 2.3 Analysing the life processes that animals undergo Animals Life Processes Excrete Defecate Breathing Reproduce To get rid of waste product Organs Lay Eggs Give Birth from their bodies cat butterfly tiger bird bat whale Lungs Gills Lung-book Moist Trachea • monkey • fish • crab Skin Structure • bird • prawn • frog • insects • whale • earthworm
  7. 7. Science Year 4INVESTIGATING LIVING THINGS2. Living Things Undergo Life Processes the part of plant that responds plants respond to stimuli. to water water, sunlight, touch, gravity.various ways plants reproduce Rootsthrough…seeds, spores, suckers, stem cutting,leaves, underground stem. the part of plant that responds to gravity. 2.4 Roots Life processes plants undergo the part of plant that responds to sunlight. what will happen to the world if plants do not reproduce. Shoot no food supply. plants reproduce. Seeds – balsam, corn, durian the part of plant that responds Spores – fern, mushroom to touch. Suckers – banana, pineapple why plants need to reproduce Stem cutting – hibiscus, rose, tapioca Leaves – bryophyllum, begonia to ensure the survival of the species. Stem – potato, onion, ginger and lily
  8. 8. 3.1 animals have specific characteristics and behaviour to protect themselves Special characteristics The special characteristics and special behaviour of animals that protect them behaviour of animals help to of animals that protect them protect them from danger. from danger. from danger. Sharp claws Thick and hard skin To protect themselves and theirTo prevent their enemies from injuring Young from the enemies- lion ,cat, Eg. elephant Bears, and eagle. Hard shell Pretend to deadSnails and tortoise retract their head To trick their enemies –e.g.: beetleAnd legs into the shell when the are Attacked by enemies Camouflage Hard scales Has body colour or patterns that that are Pangolins and crocodiles have hard Similar to the surrounding scales To protect their bodies from injuries Spines Spray black ink Raise the sharp spines when Dark surrounding helps the animal not the enemies advance towards them to been seen by enemies Eg. porcupine – e.g: octopus, squid Horns Poisonous sting or fangs Use their horn to attack enemies. Can hurt and kill enemies-e.g..: scorpion, Eg. buffalo centipede snake , bee.
  9. 9. 3.2/3.3 Animals have specific characteristics and behaviour to protect themselves from extreme weather and survive specific characteristics and how specific characteristics and behaviour of animals that protect behaviour of animals help to protect them from very hot and cold weather. them from very hot or cold weather. Hot weather Cold weather Thick Fur Polar bears have thick fur to prevent the body Wrinkled Skin From losing heat to cold surroundings.Elephant ,hippopotamuses and buffaloes lose body heat through wrinkled skins Fat Layers Under The Skins Wallowing Penguins, seals, and whales have fat layers underElephant, hippopotamuses and buffaloes their skin to keep their bodies warm keep their body cool by wallowing in mud holes Small Ears Seals and Walruses have small ears to prevent Heat loss from their bodies. HumpsCamels store food and water in the form Hibernate Of fats in the humps on their back. Polar bears hibernates during extreme cold Weather
  10. 10. 3.4 Plants have specific characteristics to protect themselves from enemyThe specific characteristics How the specificof plants that protect them characteristics offrom enemies plants help to protect them from enemies.Produces characteristics that latex protect plants. Have thorns poisonous Have fine hairs Close leaflets when touch
  11. 11. 3.5 Plants have specific characteristics to protect themselves from dry region and strong wind strong wind dry region Eg: Coconut tree, bamboo tree, . Eg : cactus mangrove treea. Long roots to absorb waterb. Succulent stem can store a. Have stems that bend easily water b. Have buttress rootsc. Thorn can prevent c. Have separated leaves the excessive loss of d. Needle- shaped leaves water
