Summary

• Description:

  The MS Word document comprises the Grade 9 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 70 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.
    • Questions cover a broad range of topics from Biology, Chemistry, and Physics.
    • Biology topics include: The cell as the basic unit of life, human digestive system (absorption), differences between plant and animal cells (presence of chloroplasts), viral diseases (HIV/AIDS), prevention of waterborne diseases, plant anatomy (root function), and photosynthesis (products).
    • Chemistry topics include: Electron arrangement (e.g., Chlorine), chemical formulas (e.g., H₂O), physical vs. chemical changes, indicators of chemical reactions, acids and bases (alkaline substances), element symbols (e.g., Sodium), separation techniques for mixtures (e.g., evaporation), changes of state (evaporation), acid-base reactions and their products (salt), and physical properties of substances (e.g., density).
    • Physics topics include: Greenhouse gases, forces (friction), simple machines (pulleys), energy transformations (solar panels), units of physical quantities (electric current - Ampere), series circuits, electrical conductors, magnetic fields, sources of light energy (the Sun), the speed of sound in different media, renewable energy sources (geothermal energy), and boiling point of water.
  • SECTION B (40 marks)
    • This section consists of 10 short, structured questions (numbered 31 to 40), with marks allocated as indicated in the paper.
    • Question 31 (Chemistry): Definition of an atom, chemical symbols (Potassium, Iron, Oxygen), and the difference between an element and a compound.
    • Question 32 (Physics): Analysis of a simple electric circuit diagram (switch state, bulb behavior), definition of pressure, comparison of pressure exerted (e.g., high heel vs. elephant foot), and calculation of weight and minimum pressure exerted by a block.
    • Question 33 (Biology): Definition of reproduction, labeling parts of the human male reproductive system, and explaining functions of a specified part of the human female reproductive system.
    • Question 34 (Physics): Stating the law of conservation of energy, describing energy transformations (e.g., in a torch, a falling stone), and explaining heat transfer mechanisms (conduction, convection, radiation).
    • Question 35 (Biology/Chemistry): Identifying the process of diffusion (e.g., ink in water), stating factors affecting the rate of osmosis, and giving the importance of osmosis in living things.
    • Question 36 (Chemistry): Definition of a mixture, describing a method to separate a mixture (e.g., sand and iron filings), and giving differences between a mixture and a compound.
    • Question 37 (Biology): Naming parts of a flower from a diagram and stating characteristics of insect-pollinated flowers.
    • Question 38 (Biology): Stating reproductive parts in a flower, differences between wind-pollinated and insect-pollinated flowers, and mentioning modes of seed dispersal.
    • Question 39 (Chemistry): Naming parts of an atom from a diagram (electron, energy level, proton, neutron) and identifying the atomic number of an element from a diagram.
    • Question 40 (Physics): Definition of force, stating the SI unit of force, giving effects of force on an object, and calculating work done.
