Concepts

This study delivers 1 primary concept and 4 secondary concepts.

Primary concept: Habitat Suitability and Adaptation (SC-KS1-C036)

Type: Knowledge | Teaching weight: 3/6

The understanding that living things are suited to the habitats in which they live - they possess features and behaviours that allow them to survive in that habitat's specific conditions. For example, polar bears are suited to cold Arctic habitats (thick fur, fat layer); camels are suited to hot deserts (hump for fat storage, wide feet for sand). At KS1 this is introduced as a descriptive observation; causal explanation through natural selection is not expected until Year 6.

Teaching guidance: Use photographs of animals in their natural habitats and discuss how the animal is suited to its environment. Focus on observable features (thick fur in cold animals, streamlined shape in swimming animals). Avoid asserting that animals 'chose' their features or that adaptations were deliberately acquired. Key vocabulary: suited, adapted, feature, habitat, survive, conditions, suited to, environment Common misconceptions: Children often think animals actively chose or developed their adaptations (intentional fallacy). Some think all animals could survive in all habitats if they wanted to. Children may think adaptation happens within a single animal's lifetime rather than over many generations.

Differentiation

Model response (Entry): Its webbed feet help it paddle through the water.

Model response (Developing): A rabbit has long ears to listen for predators like foxes. It has strong back legs for running away quickly. Its brown fur helps it blend in with the grass and soil.

Model response (Expected): A cactus has thick, waxy stems that store water inside so it can survive long periods without rain. Instead of big leaves, it has spines which lose much less water to evaporation and protect it from animals trying to eat it for the water inside. Both features help the cactus cope with the desert's extreme heat and lack of water.

Model response (Greater Depth): A seal has thick blubber (fat) under its skin to keep warm, smooth fur that is waterproof, and flippers for swimming fast. A penguin has a thick layer of overlapping feathers that trap air for insulation, a layer of fat, and flipper-like wings for swimming. Both have a layer of insulation (blubber/feathers) to survive the cold, and both have streamlined bodies for swimming. Even though one is a mammal and one is a bird, they have similar solutions to the same problem — staying warm and catching fish in freezing water.

Secondary concept: Pattern Recognition in Science (SC-KS1-C007)

Type: Process | Teaching weight: 2/6

Noticing regularities, relationships and trends in observations or data. At KS1, pattern recognition includes seeing that things change in predictable ways (seasons, plant growth) and that groups of things share common characteristics. Recognising patterns is central to all scientific disciplines and leads to generalisation and the formation of scientific laws and principles.

Differentiation

Secondary concept: Using Secondary Sources (SC-KS1-C008)

Type: Skill | Teaching weight: 1/6

Finding scientific information from books, photographs, videos, internet resources and by asking knowledgeable people. At KS1, pupils learn that some questions cannot be answered by observation or investigation alone, and that scientists build on the knowledge and work of others. This is an important habit of scientific inquiry.

Differentiation

Secondary concept: Interdependence in Habitats (SC-KS1-C037)

Type: Knowledge | Teaching weight: 3/6

The understanding that plants and animals in a habitat depend on each other for survival. Plants produce food and oxygen that animals need; animals may pollinate plants or disperse seeds; predators control prey populations; decomposers recycle nutrients. At KS1 this is introduced simply: pupils recognise that if a key organism is removed, others are affected. This concept develops into understanding of food webs and ecosystems in KS2.

Differentiation

Secondary concept: Simple Food Chains (SC-KS1-C038)

Type: Knowledge | Teaching weight: 3/6

A food chain is a sequence showing who eats whom, starting always with a producer (a green plant that makes its own food through photosynthesis) and showing the flow of energy through herbivores, omnivores and carnivores. At KS1 pupils construct and read simple linear food chains (3-4 organisms) from their local habitat. The concept of energy transfer from food is not formally introduced until KS2.

Thinking lens: Patterns (primary)

Key question: What patterns can I notice here, and what do they allow me to predict? Why this lens fits: Data from repeated investigations reveals patterns that allow pupils to generalise their findings beyond the specific test conditions. Question stems for KS1:

What is the same about these?

What is different?

What comes next?

Can you sort these into groups?

Secondary lens: Cause and Effect — Fair testing and investigations are designed to isolate variables and establish causal relationships — the cognitive demand is reasoning from controlled evidence to causal claims.

Session structure: Research Enquiry

Research Enquiry

A structured approach to answering questions through secondary research. Pupils formulate a research question, select appropriate sources, take and organise notes, synthesise findings from multiple sources, and present their conclusions. Develops information literacy alongside subject knowledge.

question → source_selection → note_taking → synthesis → presentation Assessment: Research report or presentation that answers the original question using evidence from multiple sources, with evaluation of source reliability where appropriate.

Equipment and safety

Equipment:

food chain picture cards

non-fiction books about animals and habitats

video clips of animals feeding

arrow cards for building chains

large paper for class food chain display

Safety notes: No specific physical hazards. If using video clips of predation, preview to ensure content is age-appropriate and not distressing. (Hazard level: low)

---

Expected outcome

Children construct simple food chains (3-4 links) showing what eats what in a familiar habitat. They identify that plants are the starting point of most food chains (producers), that some animals eat plants (herbivores) and others eat animals (predators), and that the arrows show the direction of energy transfer.

Recording format: picture food chains, verbal descriptions

Enquiry type

Research Using Secondary Sources

An enquiry where pupils answer scientific questions using information from books, websites, databases, and other secondary sources rather than first-hand investigation. Used when the question cannot be answered by practical investigation in the classroom (e.g. space, evolution, body systems, historical scientific discoveries).

Question stems:

What does the evidence tell us about [topic]?

How do scientists explain [phenomenon]?

What do we know about [topic] and how do we know it?

Teacher scaffold:

What question are we trying to answer?

Where can we find reliable information about this?

What are the key facts and ideas from this source?

Do different sources agree? If not, why might they differ?

What is the answer to our question, based on the evidence?

Why this study matters

Research enquiry is the appropriate type here because food chains in wild habitats cannot be directly observed in a single lesson. Using picture cards to physically build food chains makes the abstract relationship (energy flows from plant to herbivore to predator) concrete and manipulable. Starting from the habitat explored in SE-KS1-008 connects the food chain concept to real organisms the children have already encountered.

---

Pitfalls to avoid

Children draw arrows pointing from predator to prey ('the fox eats the rabbit') rather than in the direction of energy transfer — teach the arrow as 'is eaten by' or 'gives energy to'

Food chains start with an animal rather than a plant — always ask 'Where does the energy come from first?' to establish plants as the starting point

Children confuse food chains with food preferences — food chains describe ecological relationships, not what animals like to eat

Sensitive content

Predation can be distressing for some young children — focus on the ecological relationship rather than graphic details of hunting

Cross-curricular opportunities

Working scientifically skills (KS1)

These disciplinary skills should be woven through teaching, not taught in isolation:

Asking questions — Posing simple questions about observations and recognising that different types of question require different approaches to find an answer, including tests, observations over time, and looking in books.

Identifying and classifying — Sorting and grouping objects, organisms or materials according to their observable characteristics, recognising that things can be classified in more than one way depending on which features are selected.

Evaluating evidence and understanding scientific knowledge development — Critically evaluating data for random and systematic error, and understanding how scientific methods and theories evolve as new evidence emerges — including the roles of publication, peer review and replication in establishing trustworthy scientific knowledge.

Recording data in varied formats — Presenting collected data and results in an appropriate range of formats — including scientific diagrams, labelled drawings, classification keys, tables, bar charts, line graphs and scatter graphs — selecting the format suited to the type of data.

Making systematic observations and measurements — Conducting careful, methodical observations and taking accurate measurements using standard units and a range of scientific equipment, including thermometers and data loggers, with Upper KS2 pupils also taking repeat readings to improve reliability.

Interpreting data and identifying patterns — Analysing observations and quantitative data to identify trends, correlations and patterns, and using these findings to draw evidence-based conclusions that go beyond a simple restatement of the results.
