  • Explains neuroplasticity: repeated neural pathways become stronger and faster — this is the biological mechanism of learning and skill development

• How the Lungs Work

  Explain how the respiratory system works in detail: air travels through the nose/mouth, down the trachea, into bronchi and bronchioles, reaching tiny air sacs (alveoli) in the lungs where oxygen passes into the blood and carbon dioxide passes out

  • Trace the air pathway: nose/mouth → trachea → bronchi → bronchioles → alveoli

  • Explain why there is no single simple solution to rainforest protection
  • Suggest how different groups (governments, businesses, consumers, scientists) can each contribute to a better outcome

• Rainforests & Global Climate

  Understand the connection between rainforests and global climate — rainforests absorb carbon dioxide and release oxygen through photosynthesis, store enormous amounts of carbon in their biomass, and generate rainfall through transpiration; when forests are burned or cleared, stored carbon is released as CO₂, accelerating climate change and disrupting regional rainfall patterns

  • Explain that rainforests absorb CO₂ and store carbon in their trees, acting as a carbon sink
  • Describe how deforestation releases stored carbon back into the atmosphere, accelerating climate change
  • Explain that transpiration from rainforest trees generates rainfall, and losing trees disrupts rain patterns

• Deforestation Causes & Scale

  • Explain why this concentration of species makes rainforests a conservation priority
  • Give specific examples of rainforest biodiversity, such as one hectare containing more tree species than all of northern Europe

• Nutrient Cycling in Thin Soil

  Understand the paradox of nutrient cycling in rainforests — despite lush growth, rainforest soil is typically thin and nutrient-poor because most nutrients are locked in living organisms, not the soil; decomposition is rapid in the warm, wet conditions, and nutrients released from dead material are immediately absorbed by plant roots and fungi, creating a fast, closed-loop recycling system

  • Explain that rainforest soil is thin and nutrient-poor despite the lush growth above
  • Describe the rapid decomposition cycle: dead material → decomposers → nutrients released → immediately absorbed by roots
  • Explain why clearing rainforest for farming fails after a few years — once the trees are gone, the nutrients are lost

Insects & Minibeasts

• Insects in ecosystems

  Insects in ecosystems: the many roles insects play. Pollinators (bees, butterflies, hoverflies), decomposers (dung beetles, fly larvae), food source for birds, bats, fish, and frogs, and pest controllers (ladybirds eating aphids). The thought experiment: what would happen if all insects disappeared?

• The most successful animals on Earth

  The most successful animals on Earth: there are roughly one million described insect species, and scientists estimate 5–10 million may exist. More insect species than all other animal groups combined. Why so many? Small body size means less food needed, fast reproduction with many offspring, flight allows reaching new habitats, and the exoskeleton is incredibly versatile.

  • Give at least two reasons why insects are so successful such as small size, fast reproduction, or flight
  • Compare insect diversity to another animal group, explaining that there are far more insect species than mammals or birds

  • Name at least three threats to insect populations such as habitat loss, pesticides, and light pollution
  • Explain why declining bee populations are a problem for humans and the food we eat
  • Suggest at least two actions that children or families can take to help insects such as planting wildflowers or joining a butterfly count

• Insect Adaptations

  Adaptation and evolution in insects: peppered moths as a famous example of natural selection (dark moths survived better on soot-covered trees during the Industrial Revolution). Stick insects evolved to look like twigs. Ant-mimicking spiders evolved to fool predators. How small changes over many generations lead to remarkable disguises.

  • Retell the peppered moth story and explain how the environment changed which colour moth survived best
  • Describe how a stick insect's body shape is an adaptation that helps it avoid being eaten
  • Explain that adaptations develop over many generations through natural selection, not during one insect's lifetime

  • Explain what information a bee conveys through its waggle dance, including direction and distance to flowers
  • Describe the monarch butterfly migration and explain why it is remarkable in terms of distance and navigation

• Types of Metamorphosis

  Complete vs incomplete metamorphosis. Complete: egg → larva → pupa → adult (butterflies, beetles, flies). Incomplete: egg → nymph → adult — the nymph looks like a small version of the adult and moults as it grows (grasshoppers, dragonflies, crickets). Why do some insects transform completely while others grow gradually?

  • Compare complete and incomplete metamorphosis by describing the stages of each on a diagram
  • Classify at least three insects into the correct metamorphosis type such as butterfly (complete) and grasshopper (incomplete)
  • Explain that nymphs resemble adults while larvae look completely different from their adult form

• Insect anatomy in depth

  Insect anatomy in depth: compound eyes made of thousands of tiny lenses, spiracles (breathing holes along the body), diverse mouthparts (chewing mandibles in beetles, sucking proboscis in butterflies, sponging pad in flies), and moulting the exoskeleton to grow. Biomimicry — how engineers copy insect designs.

  • Describe at least two specialised insect structures such as compound eyes or spiracles and explain their function

  Develop a model to describe ways the geosphere, biosphere, hydrosphere, and atmosphere interact as connected Earth systems

  • Name the four Earth systems: geosphere (rock/land), hydrosphere (water), atmosphere (air), biosphere (living things)
  • Describe at least two interactions between different Earth systems with examples
