Summary

• Description:

  The MS Word document comprises the Grade 8 Integrated Science Paper 1 (Theory) Mid Term 2 Exam 2025 with Marking Scheme. The PDF version is also available upon your request.

  The exam paper, titled "INTEGRATED SCIENCE (Theory) PAPER 1," is divided into two sections, A and B. The total time allocated for the paper is 1 hour 40 minutes. The exam is marked out of a total of 80 marks (Section A: 30 marks, Section B: 50 marks).

  The structure and content of the exam are as follows:

  • SECTION A (30 marks)
    • This section consists of 30 multiple-choice questions, each worth 1 mark.
    • Topics covered span Biology, Chemistry, and Physics:
      • Safety: Classes of fire (e.g., Class B for flammable liquids).
      • Biology: Human digestive system (absorption in the small intestine), human respiratory system (lungs), blood components and functions (red blood cells transporting oxygen), disease transmission (e.g., malaria by mosquitoes), cell biology (parts of plant and animal cells, reason for staining specimens).
      • Chemistry: States of matter and changes of state (sublimation, melting, effect of impurities on boiling point), mixtures and solutions (e.g., salt solution), separation techniques (filtration, decantation), composition of air (most abundant gas: Nitrogen), the carbon cycle (role of photosynthesis), atomic structure (protons, neutrons, electrons), elements and symbols (e.g., Copper - Cu), chemical reactions and products (e.g., formation of sodium chloride), laboratory apparatus (measuring cylinder and its use), density (definition and calculation), physical vs. chemical changes.
      • Physics: Units of measurement (force - Newton), concepts of energy (definition, chemical energy in food), the fire triangle (fuel, heat, oxygen), firefighting methods (smothering), electrical conductors (copper), kinetic theory of matter.
      • General Processes: Osmosis and diffusion.
  • SECTION B (50 marks)
    • This section consists of 10 short, structured questions with varying mark allocations.
    • Biology Topics:
      • Characteristics of living organisms; the human excretory system (kidney products, importance of excretion).
      • The human circulatory system (main organ, functions of arteries and veins, importance, common diseases).
      • Osmosis (experimental observation, factors affecting rate, importance in plants).
      • Human reproduction (female reproductive system parts, fertilization, gestation period).
      • Human growth and development (physical and socio-emotional changes during adolescence, menstruation).
    • Chemistry Topics:
      • Definition of matter, properties of solids, determining the volume of irregular objects (water displacement method).
      • Laboratory apparatus: Identifying a Bunsen burner, its handling and care, and labeling its parts.
      • Differences between elements and compounds; examples of elements and compounds in different states; explaining the difficulty in separating compounds by physical means.
    • Physics Topics:
      • Pressure (definition, SI unit, application - sharp vs. blunt knife, calculation).
      • Simple electric circuits (identifying components from symbols, differentiating open and closed circuits and their effects, function of a switch).
