Grade 5 Natural Sciences and Technology builds on Grade 4 content and extends learners' scientific understanding across the four knowledge strands: Life and Living, Matter and Materials, Energy and Change, and Planet Earth and Beyond. Learners conduct increasingly independent investigations, make predictions, record data in tables and draw basic graphs. The Technology component develops design thinking — learners identify a problem, plan a solution, build a prototype and evaluate it. Grade 5 introduces the human body, food webs and ecosystems, as well as electrical and mechanical systems.
- Classification of animals: vertebrates and invertebrates
- Vertebrates: fish, amphibians, reptiles, birds, mammals — characteristics
- Food chains and food webs — producer, consumer, predator, prey
- Ecosystems: biotic and abiotic components
- Human impact on ecosystems: pollution, habitat destruction, conservation
- Adaptation: how animals are suited to their environment
- Technology: design a simple model to reduce environmental impact
- Investigation: classify local animals using identification keys
- Mixtures: homogeneous and heterogeneous mixtures
- Solutions: solute, solvent, solution — examples in daily life
- Separating mixtures: filtering, evaporation, sieving, decanting, magnetism
- Dissolving: factors affecting rate of dissolving — temperature, stirring, particle size
- Conservation of mass when mixing materials
- Chemical change vs physical change — introduction
- Technology: design a water filtration device
- Investigation: test factors affecting how quickly sugar dissolves
- Electric circuits: series and parallel circuits
- Circuit diagrams: symbols for battery, wire, bulb, switch, resistor
- Conductors and insulators — revision and extension
- Effect of adding more batteries or bulbs to a circuit
- Magnets and electromagnetism — introduction
- Sound energy: vibration, pitch, volume, reflection
- Technology: build and modify a simple circuit
- Investigation: compare brightness of bulbs in series vs parallel
- The water cycle: evaporation, condensation, precipitation, collection
- Weather: cloud types, rainfall, temperature, wind — reading weather maps
- Climate vs weather — difference and South African examples
- Rocks and minerals: properties and uses in technology
- Fossils: formation and what they tell us about the past
- Our solar system: planets, moons, asteroids, comets
- Technology: build a model of the water cycle
- Investigation: collect and analyse local weather data
Understand the fair test process. In tests you are often asked to describe or design a fair test. Remember: change only ONE variable, keep everything else the same, and observe what happens.
Use labelled diagrams — they earn marks. Labelled diagrams of plants, animals, circuits, the water cycle or the solar system are worth marks. Practise drawing and labelling them from memory.
Learn the key vocabulary. Natural Sciences uses precise technical vocabulary. Words like 'photosynthesis', 'vertebrate', 'conductor' and 'decomposer' have specific meanings — use them correctly.
Connect science to real life. The best way to remember content is to connect it to real examples. When you study the water cycle, think of rain. When you study food webs, think of your local environment.
Know the difference between physical and chemical change. Physical change is reversible (cutting, dissolving). Chemical change is irreversible (burning, rusting). This distinction appears in almost every Grade 5 and 6 NST test.
