Summary

• Description:

  The MS Word document comprises Grade 7 Integrated Science Paper 1 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 exam tests Grade 7 Integrated Science learners on laboratory safety, basic science skills, mixtures and separation methods, light, acids and bases, the microscope, levers, and density — assessing cross-disciplinary science knowledge as required under the KJSEA Junior School curriculum.

  • Month Administered: June 2026
  • Duration: 1 Hour 30 Minutes
  • Total Marks: 50 (Section A: 20 marks; Section B: 30 marks)
  • Structure:
    • Section A (20 marks) — Multiple-choice questions; all compulsory
    • Section B (30 marks) — Structured short-answer and calculation questions; all compulsory

  It covers the following topics:

  • Section A
    • Components of Integrated Science — Biology, Chemistry, Physics (Kiswahili excluded)
    • Laboratory safety — causes of accidents (electric shock wrongly linked to corrosive substances), first aid kit components, laboratory hazard symbols (oxidizer, flammable, corrosive, biohazard)
    • Basic science skills — manipulative skills, measuring volume with apparatus, basic quantities and SI units (electric current wrongly matched to Voltage)
    • Laboratory apparatus — identifying a voltmeter from diagrams
    • Light — reflection (light bounces off a surface), materials that cannot make a shadow (plane mirror)
    • Product packaging — information (manufacture date, quantity, storage instructions)
    • Reasons for studying Integrated Science — understanding nature and solving problems
    • Microscope — labeled parts (arm, diaphragm, stage, base), coarse adjustment knob for rough focus
    • Levers — crowbar and claw hammer in similar positions
    • Separation of mixtures — chromatography for coloured mixtures
    • Acids and bases — iodine is not an acid-base indicator; lemon juice, vinegar, orange juice as acids; pH scale (T=2 most acidic, R=14 strong base)
  • Section B
    • Laboratory hazards — definition, three common hazards, two reasons for laboratory safety
    • Mixtures — two types (homogeneous and heterogeneous); separation methods (simple distillation, fractional distillation); distillation diagram (method, substance at P, role of condenser)
    • Density — definition and SI unit; calculating density (mass 50g ÷ volume 10cm³ = 5g/cm³)
    • Bunsen burner — identifying parts A and B; air hole function; base for stability; three ways of caring for it
    • Basic science skills — manipulative, conclusion, communication/recording, hypothesis/prediction
