  Download editable Grade 10 Power Mechanics Term 3 Lesson Plans 2026 - KICD Curriculum Design in MS Word format. A PDF version is also available upon your request.

  This comprehensive technical educational resource contains fully structured lesson plans for Grade 10 Power Mechanics under the Senior School Competency-Based Curriculum (CBC). Designed for classroom theory and hands-on automotive workshop instruction across Term 3, the downloadable lesson plans cover 40 distinct lessons across 9 weeks, with Week 7 reserved for the official mid-term break. The resource equips teachers with detailed guidance on internal combustion engines, kinematics, and diagnostic servicing.

  The lesson plans are aligned with the Grade 10 Power Mechanics Textbook, workshop manuals, cutaway engine models, precision measuring instruments, and manufacturer service specification tables.

  The lessons are organized under the following comprehensive strand and substrands:

  • 4.0 Engines

    • 4.1 Introduction to Engines: Technical definitions of prime movers and engines; thermal-to-mechanical energy transformation; applications in transportation, agriculture, and industry; structural components of single-cylinder engines; reference limits including Top Dead Centre (TDC) and Bottom Dead Centre (BDC); cylinder bore diameter and stroke length dimensions; engine displacement capacity in cc and litres; horsepower in hp and kW; and mathematical capacity calculations using the formula Vs = (pi x Bore² x Stroke x n) / 4.

    • 4.2 Classifications of Engines: Classification by fuel type, strokes per cycle, cooling method, cylinder layout, and ignition system; Internal Combustion (IC) versus External Combustion (EC) engines; engine size categories; fuel types including petrol, diesel, LPG, CNG, and biofuels; Spark Ignition (SI) versus Compression Ignition (CI); air-cooling fins versus liquid-cooling radiator circuits; and workshop field visits with technical data tabulation.

    • 4.3 Types of Engines: Single-cylinder versus multi-cylinder power delivery and vibration balancing; cylinder arrangements including Inline/Straight, V-type, Horizontally Opposed/Boxer, and Wankel Rotary engines; speed categories based on RPM; four-stroke cycle operation covering induction, compression, power, and exhaust; 720-degree crankshaft rotation and 2:1 camshaft gear reduction; two-stroke cycle mechanics involving crankcase scavenging and inlet, transfer, and exhaust ports; 360-degree crankshaft rotation; operational comparison of two-stroke and four-stroke engines; and machinery application matching.

    • 4.4 Engine Components and Diagnostic Measurement: Stationary structural components such as the cylinder block, cylinder head, crankcase, oil sump, rocker cover, water jackets, and oil galleries; moving components including the piston, gudgeon pin, compression and oil rings, connecting rod, crankshaft counterweights, camshaft lobes, valves, and rocker arms; technical freehand sketching; precision service measurements using internal micrometers, bore gauges, outside micrometers, and feeler gauges; and evaluation of wear data against manufacturer service limits.

  Key practical skills and theoretical competencies developed across the lessons include:

  • Using vernier calipers and depth gauges to take linear engine measurements and calculate total displacement in cubic centimeters.

  • Drafting technical end-view diagrams of Inline, V-type, and Opposed cylinder engine blocks with correct dimensioning.

  • Tracing thermodynamic gas exchange cycles, valve lead and lag, and valve overlap using circular timing degree wheels.

  • Assembling pistons, connecting rods, and gudgeon pins using circlip pliers while observing workshop safety procedures.

  • Operating valve spring compressors to assemble and inspect intake and exhaust valve keepers safely.

  • Measuring cylinder bore wear at top, middle, and bottom depths on thrust and non-thrust axes to calculate bore taper and ovality.

  • Measuring crankshaft main and connecting rod journals using outside micrometers to identify journal wear.

  • Squaring piston rings in cylinder bores and measuring end gaps with blade feeler gauges against workshop service limits.

  Each lesson plan follows an organized five-step format featuring Introduction, Lesson Development, Conclusion, Extended Practice Tasks, and Teacher Self-Evaluation spaces.

  This downloadable Word and PDF resource provides a complete, curriculum-aligned roadmap for secondary technical teachers handling Grade 10 Power Mechanics, combining theoretical knowledge, practical workshop skills, precision measurement, engine diagnostics, and workplace safety.
