Natural Science (Requirements for growth (Sunlight (Too little sunlight:…

- - - - Distance between leaves and attachment to stems is wide
      - Fewer flower buds and flowers
      - Stems are lanky
      - Plant leans towards light source
    - - Flower petals dry out
      - Leaf edges look burnt or dry
      - Flower colour is faded or washed out
      - Entire plant stem is weaker and droops
  - - - Lower leaves are yellow
      - Plant looks wilted
      - Roots will rot or be stunted
      - No new growth
      - Young leaves turn brown
      - Soil will appear green (algae)
  - - - Foliage: leaves
    - - Will grow short and thin, instead of tall and thick
  - - - Increased growth rate problems
      - Weakened plants more susceptible to pests
      - Wilting vs. Browning
    - - Chilling vs. Freezing
      - Hardening
      - Wilting
  - - - 6-8 days: sprout
      - 4 - 6 weeks: Emerging process, 8 - 12 leaves completely unfolded
      - 8 weeks after emerging: Leaves already unfolded and corn plant is fully grown
- - - - Fins
      - Legs
      - Arms
  - - - Mouth
      - Nose
      - Eyes
      - Ears
- - - - Animals and plants need protection from predators (animals that will eat them)
      - Shelter provides protection by providing them with a place to escape to
      - Plants have adaptations that protect them from being destroyed by predators
        
        Adaptations: Characteristics that they have developed over time
        
        Some have thorns
        
        others grow in thick bushes, outer leaves are eaten to protect inner leaves
      - Some animals use camouflage to protect themselves and catch their prey
        
        Prey: animals predators will eat
        
        Camouflage: animal does something to blend itself into it's surroundings. Other animals can't see it.
        
        Some animals change their colour (Chameleons)
        
        Some animals look similar to their habitat (Stick insects)
        
        Animals like lions and giraffes are of a similar colour to their habitat to blend in
    - - Animals and plants need to live in a place with enough food and water
      - Animals get their food from plants or other animals (lion eats a zebra)
      - Plants make their own food but still need nutrients in the soil
      - Animals can move out of an area to get food or water, plants cannot, they will die
      - In a good habitat, plants will thrive and scatter new seeds and bear fruit
    - - Animals
        
        Plants and animals need shelter from danger and weather conditions like excessive cold, heat, rain or wind
        
        Some dig burrows (moles)
        
        Some find shelter in bushes and trees (small mammals, birds)
        
        Caves (bats)
        
        Holes in the ground (spiders, earthworms)
        
        The habitat must be suitable for the animal to live in
        
        Some animals build nests (birds, squirrels)
      - Plants
        
        Some plants grow around big rocks and boulders that shelter them from wind and weather
        
        Some grow at the foot of trees
        
        Some plants grow next to each other forming thick bushes that provide shelter
    - - Animals and plants must live in a place where they can breed offspring and raise them to adulthood
        
        Offspring: Babies
      - Some fish lay their eggs in sheltered reefs away from currents
      - Some small animals raise their young in burrows where they will be same until they're older
      - Some plants use animals to disperse their seeds to new areas where they can grow into healthy strong plants
- - - - All living things move
      - Even if that movement is slow
    - - Process involved in the exchange of oxygen and carbon dioxide between an organism and the environment
    - - process by which an organism takes food and uses it for growth, maintenance and energy
    - - Excretion is when an organism gets rid of waste products which may poison the cell
      - All living things excrete.
    - - Seen in all living things
      - involves using food to produce new cells
      - The permanent increase in cell number and size is called growth.
    - - All living things have the ability to produce offspring
    - - All organisms detect and respond to select external stimuli.
      - It must be able to detect the properties of it's environment and act appropriately.
      - A living thing must respond to changes in their environment
  - - - Seeds germinate into plants.
      - Eggs hatch into birds.
      - Yeast begins to grow
