Summary

• Description:

  Download editable Grade 9 Rationalized Integrated Science Term 3 Record of Work 2026 - KLB in Microsoft Word document format. A PDF version is also available upon your request.

  Following the KLB Integrated Science Grade 9 syllabus course book (pages 115–195), this editable Record of Work details 9 academic weeks with 5 scheduled periods per week, delivering 45 complete lesson logs. It provides complete transparency into delivered laboratory experiments, ecological investigations, and physics modules.

  This Record of Work tracks curriculum progress across the following core strands and sub-strands:

  • Living Things and Their Environment:
    • The Interdependence of Life: biotic and abiotic components, competition, predator-prey adaptations, parasitism, symbiosis in root nodules/lichens, and saprophytism
    • Abiotic Factors: measuring environmental, soil, and water temperatures with thermometers; measuring light with Secchi discs/meters; testing atmospheric humidity with cobalt(II) chloride paper; measuring wind with constructed wind vanes and windsocks; soil/water pH testing with universal indicator paper
    • Energy Flow: constructing food chains, multi-trophic ecosystem food webs, Kenyan National Park wildlife trophic interactions, decomposers at compost sites, and debates on human environmental impacts
  • Force and Energy:
    • Curved Mirrors: structural curvature of concave, convex, and parabolic reflectors; pole, center of curvature, radius of curvature, principal axis, principal focus, and experimental focal length determination
    • Ray Diagrams: candle projection on screens, virtual upright convex images, incident ray sketch rules, and scaled ray diagrams for varied object positions (beyond C, at C, between C and F, at F, and between F and P)
    • Curved Mirror Uses: torches, solar concentrators, shaving mirrors, astronomical reflecting telescopes, dental mirrors, and road safety convex mirrors
    • Waves: wave generation in water basins and audio speakers, longitudinal compression in slinky springs, peak amplitude measurement, wavelength, phase mapping, periodic time measurement with stopwatches, and wave equation derivation (v = f λ)
    • Wave Properties and Applications: ripple tank refraction and diffraction, remote sensing radiation mechanisms, medical diagnostic uses (ultrasound, X-ray, MRI), laser surgery, radiation therapy, and telecommunication systems
  • End Term Assessment and Term Closing:
    • Comprehensive summative theory examinations and practical science laboratory skill tests
    • Script marking, score debriefs, learner portfolio organization, and administrative clearance

  Logged instructional methods involve ripple tank barrier experiments, wind vane fabrication, cobalt chloride humidity testing, optical bench candle projections, thermometer readings, and stop-watch timing drills. Assessment tools include lab checklists, concept map evaluations, problem sets, and weekly administrative sign-off columns for the Headmaster.
