Summary

• Description:

  The MS Word document comprises Grade 8 Integrated Science Paper 2 Mid Term 2 2026 Exam with Marking Scheme. The PDF version is also available upon your request. The marking scheme is in a different document.

  This is a practical-based exam that assesses Grade 8 Integrated Science learners on hands-on investigations involving diffusion, osmosis, electrical circuits, and acid-base indicators — evaluating experimental skills, observation, and scientific reasoning as required under the KJSEA Junior School curriculum.

  • Month Administered: June 2026
  • Duration: 1 Hour 40 Minutes
  • Total Marks: 30 (Task 1: 14 marks; Task 2: 16 marks)
  • Structure:
    • Task 1 (14 marks) — Three practical activities: diffusion (10 marks), osmosis (embedded in diffusion task), electrical circuit (10 marks), and acid-base indicator testing (10 marks)
    • Task 2 (16 marks) — Extended practical questions based on experimental results

  It covers the following topics:

  • Practical Activity 1: Diffusion and Osmosis
    • Diffusion — observing ink spreading in water; naming the process; defining diffusion; factors affecting diffusion (temperature, concentration gradient)
    • Osmosis — potato strips in salt solution vs. distilled water; identifying the process; observations in each beaker
  • Practical Activity 2: Electrical Circuits
    • Drawing a labeled simple electrical circuit (dry cells, bulb, switch, voltmeter, connecting wires)
    • Instrument for measuring voltage; SI unit of voltage
    • Connecting a voltmeter in a circuit (in parallel)
    • Safety precautions when working with electrical circuits
    • Effect of an open circuit on a bulb
  • Practical Activity 3: Acid-Base Indicators
    • Definition of an acid-base indicator; common indicators in school laboratories
    • Testing four solutions (A, B, C, D) with red and blue litmus papers; recording observations and nature of each solution
    • Identifying acidic and alkaline solutions from results
