Animal CommunicationUnderstand that animals communicate in many different ways — birds sing to attract mates and defend territory, whales call across vast ocean distances, bees…
Ages 7 to 9ConceptScience // Animals of the World
BiodiversityUnderstand that biodiversity — the variety of different species in an ecosystem — is essential for healthy ecosystems, and that keystone species (like wolves in…
Ages 9 to 11ConceptScience // Animals of the World
Protecting Endangered AnimalsKnow how people work to protect endangered animals — through national parks and marine reserves, captive breeding programmes (like those that saved the…
Ages 9 to 11ConceptScience // Animals of the World
Endangered & Extinct SpeciesUnderstand why some animal species become endangered or go extinct — habitat destruction, hunting/poaching, pollution, climate change, and invasive species…
Ages 9 to 11ConceptScience // Animals of the World
Invasive SpeciesUnderstand that invasive species are animals (or plants) that have been introduced to a place where they don't naturally belong — like grey squirrels…
Ages 9 to 11ConceptScience // Animals of the World
Structural AdaptationsUnderstand that animals have structural adaptations (body features like the giraffe's long neck, eagle's talons, dolphin's streamlined shape), behavioural…
Ages 9 to 11ConceptScience // Animals of the World
SymbiosisUnderstand symbiosis — close relationships between different species — including mutualism (both benefit, like clownfish and anemones), commensalism (one…
Ages 9 to 11ConceptScience // Animals of the World
Animal IntelligenceExplore animal intelligence and complex behaviour — chimpanzees and crows use tools, dolphins recognise themselves in mirrors, octopuses solve puzzles and…
Ages 9 to 11ConceptScience // Animals of the World
The Red Queen HypothesisIntroduce the Red Queen hypothesis — species must keep evolving just to maintain fitness relative to co-evolving partners; describe predator-prey arms races…
Ages 11 to 12ConceptScience // Animals of the World
The Biodiversity CrisisQuantify the current biodiversity crisis: extinction rates 100-1000x the background rate; explain methods for measuring biodiversity loss (species-area…
Ages 12 to 14ConceptScience // Animals of the World
Sexual SelectionExplain sexual selection as a form of natural selection: runaway selection for peacock tails, bird of paradise displays, and frog calls; explain kin selection…
Ages 12 to 13ConceptScience // Animals of the World
Deep-Sea SurvivalExplain how deep-sea animals cope with crushing pressure (no gas-filled spaces, flexible proteins, pressure-adapted enzymes); describe thermoregulation extremes…
Ages 12 to 13ConceptScience // Animals of the World
Grouping Species Using DNAExplain cladistics: organisms are grouped by shared derived characters, not just similarity; how phylogenetic trees are built using molecular data (DNA sequence…
Ages 13 to 14ConceptScience // Dinosaurs & Paleontology
Dinosaurs Were RealUnderstand that dinosaurs were real animals that lived on Earth a very long time ago and are now extinct — none are alive today
Ages 5 to 7ConceptScience // Dinosaurs & Paleontology
Fossils & PalaeontologistsUnderstand that fossils are the remains of ancient living things preserved in rock, and that scientists called palaeontologists study fossils to learn about…
Ages 5 to 7ConceptScience // Dinosaurs & Paleontology
Famous Dinosaur SpeciesRecognise and name common well-known dinosaur species: Tyrannosaurus rex, Triceratops, Stegosaurus, and Brachiosaurus/Diplodocus, describing a basic feature of…
Ages 5 to 7ConceptScience // Dinosaurs & Paleontology
Plant-Eaters vs Meat-EatersSort dinosaurs into plant-eaters (herbivores) and meat-eaters (carnivores) by looking at clues like tooth shape — flat teeth for plants, sharp teeth for meat
Ages 5 to 7ConceptScience // Dinosaurs & Paleontology
Dinosaur SizesCompare dinosaur sizes to familiar things — some dinosaurs were as tall as a house, others were as small as a chicken — and understand that dinosaurs came in a…
Ages 5 to 7ConceptScience // Dinosaurs & Paleontology
Real Dinosaurs vs FictionDistinguish real dinosaurs from fictional or commonly confused creatures — pterosaurs (flying reptiles) and plesiosaurs (marine reptiles) were not dinosaurs…
Ages 5 to 7ConceptScience // Dinosaurs & Paleontology
Fossils Reveal Ancient EnvironmentsUnderstand that fossils tell us not only about ancient animals but also about ancient environments — for example, marine fossils found on a mountaintop show…
Ages 7 to 9ConceptScience // Dinosaurs & Paleontology
How Fossils FormExplain in simple terms how fossils form: an organism dies and is quickly buried in sediment; over millions of years minerals replace the remains and the…
Ages 7 to 9ConceptScience // Dinosaurs & Paleontology
Fossilised Dinosaur DungDescribe what coprolites are (fossilised dinosaur dung) and how palaeontologists analyse them to discover what dinosaurs ate, including plant fragments, bones…
Ages 7 to 9ConceptScience // Dinosaurs & Paleontology
Types of FossilsDistinguish body fossils (preserved bones, teeth, shells) from trace fossils (footprints, trackways, eggs, burrows, coprolites) and explain what each type can…
Ages 7 to 9ConceptScience // Dinosaurs & Paleontology
The Mesozoic EraPlace the three periods of the Mesozoic Era — Triassic, Jurassic, and Cretaceous — in order and understand that different dinosaurs lived in different periods…
