Animal Classification Vocabulary hard
Using classification keys to name living things requires the classification group vocabulary
Grouping Living Things hard
Must understand grouping by features before using formal classification keys
- Animal Classification Vocabulary hard
  Grouping living things requires the classification vocabulary — vertebrate, invertebrate, mammal, etc.
- Not all minibeasts are insects soft
  Insect vs non-insect sorting enriches curriculum grouping-by-features
  - The insect body plan hard
    Must know the insect body plan (6 legs, 3 parts) to distinguish insects from non-insects
    - How minibeasts move soft
      Counting legs and observing movement prepares for formal body plan study

        Must recognise common minibeasts before comparing how they move
        
        What is a minibeast? hard
        Must understand what minibeasts are before learning to name specific ones
    - Common minibeasts: naming and recognising hard

  Marine animal classification benefits from curriculum grouping-living-things skill
  - Whales & Dolphins Are Mammals hard
    Classifying marine mammals vs fish builds on whale/dolphin are mammals concept
    - Ocean Animal Variety soft
      Mammals vs fish distinction benefits from knowing ocean animal variety
  - Ocean Animal Variety hard
    Classifying ocean animals builds on knowing the variety exists

  Classifying rainforest life enriches the curriculum grouping-by-features topic (exploratory age 7 -> curriculum age 8)
  - Rainforest Plants hard
    Must know rainforest plants before classifying them
    - Rainforest Layers hard
      Plants taught in context of layers (epiphytes in canopy, lianas climbing trunks)
      - What Is a Rainforest? hard
        Must know what a rainforest is before learning its four layers
  - Rainforest Animals hard
    Must know rainforest animals before classifying them into groups
    - Rainforest Layers hard
      Animals are taught in context of which layer they inhabit
      - What Is a Rainforest? hard
        Must know what a rainforest is before learning its four layers
- Local Plants & Animals hard
  Must identify organisms in habitats before grouping them by observable features
  - Habitats & Basic Needs hard
    Must understand habitats before identifying specific organisms in habitats and microhabitats
    - Where Are the Poles? soft
      Polar regions enrich the curriculum habitats topic (exploratory age 5 -> curriculum age 6)
    - Habitat Vocabulary hard
      Describing how habitats provide for basic needs requires habitat, environment, conditions, shelter vocabulary
    - What Is a Rainforest? soft
      Rainforest habitat knowledge enriches the curriculum habitats topic (exploratory age 5 -> curriculum age 6)
    - What Living Things Need hard
      Must know basic needs of organisms before understanding how habitats provide for those needs
      - Common Plants & Trees soft
        Knowing plants helps understand what they need
      - Living Things Vocabulary soft
        Describing what plants and animals need to survive uses life processes vocabulary: nutrition, growth, sensitivity
      - Naming Common Animals soft
        Knowing animals helps understand what they need
    - What Ocean Animals Need soft
      Ocean animal needs parallels curriculum habitats/basic needs concept
      - What Is the Ocean? soft
        Ocean animal needs are contextualised by knowing what the ocean is
    - Animal Homes soft
      Animal homes concept is enriched by curriculum habitats topic
      - Animals Everywhere hard
        Animal homes builds on knowing animals live everywhere
    - Living, Dead & Never Alive hard
      Must distinguish living from non-living before understanding habitats that support living things
      - Common Plants & Trees soft
        Knowing plant names helps distinguish living from non-living
      - Living Things Vocabulary hard
        Comparing living, dead, and never-been-alive things requires the life processes vocabulary to give reasons
      - Naming Common Animals soft
        Knowing animal groups helps distinguish living from non-living
    - Minibeast Habitats soft
      Exploratory micro-habitats knowledge enriches curriculum habitats topic
