Summary

• Description:

  The PDF document comprises the Grade 9 Integrated Science Paper 2 End Term 3 2025 KJSEA Prediction Exam with Marking Scheme. The marking scheme is provided towards the end of the document.

  This practical exam paper contains two main tasks, is marked out of a total of 30 marks, and should be completed by learners within a duration of 2 hours.

  The paper assesses practical skills in Chemistry and Biology through the following tasks:

  • Task 1: Water Hardness (15 Marks)
    • An experimental task where learners test different water samples (distilled, tap, and four unknown solutions) to determine if they are hard or soft.
    • Learners are required to add a soap solution to each sample and record their conclusions based on the formation of lather or scum.
    • This task also assesses knowledge of basic science skills, required laboratory apparatus, alternative water sources, and safety precautions.
  • Task 2: Field Study of an Ecosystem (15 Marks)
    • A scenario-based task where learners analyze observations from a field study (e.g., grass, insects, birds, water, stones).
    • Learners must classify the observed items as biotic or abiotic.
    • They are also required to construct a simple food chain, explain ecological interdependencies (e.g., the role of water, effects of pesticides), and list safety rules for fieldwork.
