• Description:

  Download a printable Grade 4 Science and Technology Revision Topical Questions and Answers Booklet in PDF document format. Perfectly tailored for upper primary school teachers, learners, science tutors, and parents, this revision booklet offers rigorous topical coverage of the Grade 4 Science and Technology curriculum. Packed with observational tasks, experimental analyses, biological diagrams, and an extensive marking scheme, it is crafted to nurture scientific curiosity and practical competencies.

  The document is organized systematically, featuring all topical inquiry questions first, followed by a consolidated marking scheme at the end of the booklet. This structure empowers learners to carry out independent scientific reasoning, interpret experimental setups, and answer questions before consulting the marking guide for corrective review and feedback.

  The questions cover seven core strands incorporating life sciences, physical sciences, environmental health, and introductory technology:

  • Strand 1: Living Things:
    • Plants: 10 questions exploring characteristics of plants as living organisms (growth, reproduction, death), identifying protective safety gear when handling thorny or poisonous plants (gloves, gumboots, overcoats), illustrating eye safety wear, sorting specimens into living and non-living categories, identifying seedlings, and understanding environmental requirements for healthy plant growth.
    • Animals: 10 questions assessing characteristics of animals, classification into vertebrates and invertebrates using detailed anatomical illustrations (such as cobra, elephant, snail, and cat), safety equipment and handling tools like forceps, modes of animal reproduction (egg-laying vs. giving birth), and locomotion.
  • Strand 2: Human Body: 10 questions exploring the digestive system and dental structure. Learners identify digestive organs from a diagram (mouth/teeth, food pipe/esophagus, stomach, small intestine/ileum, large intestine/colon, and rectum), locate where digestion begins and ends, identify digestive juices, count incisor teeth, recognize dental roles in biting and cutting versus chewing and grinding, identify roots in premolars, and sketch a human molar tooth.
  • Strand 3: Environment:
    • Air Pollution: 10 questions defining air pollution, identifying common air pollutants (smoke from vehicles and factory chimneys, dust from unpaved roads, foul odors from uncleaned toilets), evaluating true/false statements regarding clean air needs, and examining negative health effects on animals and humans.
    • Water Pollution: 9 questions exploring pollutants, identifying homemade sand and charcoal water filtration systems from visual models, water purification methods such as boiling, waterborne diseases (cholera), and proper human waste disposal techniques.
  • Strand 4: Digital Technology: 7 questions focusing on everyday digital devices (desktop computers, smartphones, radios, television sets), identifying peripheral components and functions of monitors, keyboards, and the CPU, understanding coding fundamentals, solving 4x4 numerical Sudoku computational thinking puzzles, and observing electrical safety rules.
  • Strand 5: Matter:
    • States of Matter: 5 questions examining the three fundamental states of matter (solids, liquids, and gases), sorting household and environmental items (stones, air, cooking oil, pens, milk, steam, smoke) into a classification table, and evaluating shape and volume traits.
    • Properties of Matter: 10 questions investigating floating and sinking behaviors using experimental illustrations (stones submerged in water buckets, lifebuoy rings), classifying objects (feathers, coins, plastic rulers, candle wax, nails, bottle tops) into floaters and sinkers, and identifying determining factors such as shape, material type, and structural alterations.
  • Strand 6: Force and Energy:
    • Force and Its Effects: 4 main multi-part questions defining force as a push or a pull, identifying everyday applications through line drawings (pushing a wheelbarrow, lifting a box, pushing a car), and evaluating how force changes an object's speed, state of motion, shape, and direction.
    • Sound Energy: 7 questions assessing sound-producing musical instruments (flutes, guitars), modes of sound production (blowing, plucking, hitting), sound transmission in all directions, reflection of sound, and echoes in halls and large buildings.
    • Light Energy: 9 questions evaluating the rectilinear propagation of light (light traveling in a straight line through aligned cards), classifying materials into transparent, translucent, and opaque categories, and giving concrete examples of each.
    • Heat Energy: 7 questions covering thermal conduction through solid metal rods, interpreting wax-pinned pin-drop experiments, differentiating between good and poor thermal conductors, and identifying practical kitchen conductors (cooking pots/sufurias) and insulators.
  • Strand 7: Machines and Space:
    • Machines: 8 questions exploring simple levers, identifying parts of a lever (effort, load, fulcrum) on wheelbarrows and spades, recognizing how levers make work easier, and sketching beam balances.
    • Earth and Space: 8 questions covering daytime and nighttime skies (sun, moon, stars), sources of moonlight, cloud types (cumulus, nimbus, stratus), solar cardinal directions (rising in the east, setting in the west), and human agricultural activities suited for dry and windy weather conditions.

  The questions incorporate varied formats such as scientific diagrams, observational analysis, data classification tables, drawing prompts, and experimental reasoning items. These tasks challenge pupils to recall scientific facts, classify natural phenomena, and connect laboratory observations to everyday technology. It serves as an exceptional resource for teachers administering science practicals, conducting weekly revisions, or designing terminal examinations.
