Summary

• Description:

  The PDF document comprises the Grade 9 Integrated Science Paper 1 End Term 3 2025 KJSEA Prediction Exam with Marking Scheme. The marking scheme is provided towards the end of the document.

  The exam paper contains 29 questions divided into two sections, is marked out of a total of 50 marks, and should be completed by learners within a duration of 1 hour and 30 minutes.

  The paper assesses knowledge across the integrated science curriculum, including Biology, Chemistry, Physics, and Environmental Science:

  • Biology:
    • Cell Biology: Concepts of osmosis and diffusion, and the structure of a leaf (spongy mesophyll).
    • Plant and Animal Physiology: Photosynthesis and the conditions necessary for it, plant adaptations (xerophytes), reproduction in plants (pollination, seed formation), and reproduction in humans.
    • Ecology: Food chains and the classification of organisms.
    • Health: Identification of sexually transmitted diseases like Syphilis based on symptoms.
  • Chemistry:
    • Separation of Mixtures: Techniques such as simple distillation and filtration.
    • Properties of Matter: Water hardness and states of matter (freezing, condensation).
    • Metals and Reactions: Properties of metals like steel and copper, and chemical reactions such as a metal reacting with steam.
    • Atomic Structure: Electronic configuration and structure of elements.
  • Physics:
    • Forces and Pressure: Calculation of pressure in liquids and the procedure for measuring force using a spring balance.
  • Environmental Science and Safety:
    • Safety: Identification of laboratory safety symbols (e.g., toxic) and classes of fire.
    • Conservation: Water conservation methods like reusing water.
    • Waste Management: Classification of waste into biodegradable and non-biodegradable, and appropriate disposal methods like composting.
