Summary

• Description:

  This is a Microsoft Word document for Grade 10 General Science Term 3 Lesson Plans 2026 - Mentor. PDF version is also available upon your request. Aligned with the Senior School Competency-Based Education (CBE) syllabus, this educational resource provides science educators with structured, inquiry-based lesson plans. Learning content, laboratory investigations, and exercise sets are referenced directly from the textbook Mentor General Science (pages 221 to 288).

  This downloadable Lesson Plans document covers 8 instructional weeks comprising 40 complete lesson periods spanning turning moments, linear dynamics, wave properties, and magnetism:

  • Natural Physical Science:
    • Turning Effect of Force (Weeks 1–2): Defining moment of a force as turning effect; identifying fixed pivots (fulcrums) in tools (scissors, spanners, pliers, door handles); investigating factors influencing moments (force magnitude and perpendicular distance); calculating moments (M = F × d) in N·m; verifying the Principle of Moments (Sum of Clockwise Moments = Sum of Anticlockwise Moments) by balancing metre rules; calculating moments due to the weight of a uniform beam acting through its centre of gravity; analyzing couples and antiparallel forces in steering wheels and taps; and evaluating everyday applications in beam balances, crowbars, wheelbarrows, and tower cranes.
    • Linear Motion (Weeks 2–4): Distinguishing scalar distance from vector displacement; calculating displacement using vector sketches and Pythagoras; defining speed and velocity; practical fieldwork measuring sprinting velocities using stopwatches and measured tracks; converting speed units between km/h and m/s (multiplying by 5/18 or 18/5); defining acceleration and deceleration (a = (v − u)/t); applying the three equations of linear motion (v = u + at, s = ut + ½at², v² = u² + 2as); determining aircraft runway distances and impact speeds; investigating free fall gravity (g = 10 m/s²); ticker timer investigations on accelerating trolleys; solving vertical free fall calculations; evaluating steep slope dangers (runaway truck ramps, engine braking); and reviewing transport safety regulations.
    • Waves (Weeks 4–7): Defining amplitude and wavelength on transverse and longitudinal wave profiles; relating amplitude to sound loudness; defining periodic time (T) and frequency (f) in Hertz (f = 1/T); deriving and interpreting the wave equation (v = fλ); ripple tank water wave demonstrations; solving wave equation problems involving radio frequencies (kHz, MHz); demonstrating reflection of sound; stating the laws of reflection; calculating distances using echoes (d = (v × t) ÷ 2) in ship SONAR and bat echolocation; explaining sound refraction across atmospheric temperature gradients; demonstrating sound diffraction around corners and through narrow doorways; examining environmental impacts of ocean wave energy and noise pollution; evaluating coastal mitigation measures (sea walls, breakwaters, mangroves); analyzing optical retroreflection in safety reflector jackets and road studs; and explaining road mirages.
    • Magnetism and Electromagnetic Induction (Weeks 7–8): Magnetic induction and single/divided stroking methods; electrical solenoid magnetisation with DC; mechanical hammering in the North-South plane; demagnetisation through heating, mechanical shock, and AC solenoids in the East-West plane; mapping magnetic field lines around bar and U-shaped magnets using iron filings and plotting compasses; field line density and magnetic flux; defining induced EMF and Michael Faraday's discoveries; practical demonstration of electromagnetic induction using center-zero galvanometers; analyzing factors governing induced EMF (flux cutting speed, field strength, number of turns); examining applications in AC generators, grid transformers, and induction cookers; and constructing a working electric bell model utilizing a make-and-break circuit mechanism.

  The lesson plans guide learners through active scientific inquiry, addressing Key Inquiry Questions such as: "When does a system of forces achieve balance?", "How do we predict the motion of objects mathematically?", "Why do we see lightning before we hear thunder?", and "How does an electric bell use electromagnetic principles?".

  Core competencies fostered include critical thinking and problem solving, numeracy, scientific inquiry, collaboration, and digital literacy, underpinned by values of integrity in data recording, responsibility, and care for laboratory apparatus. Essential contemporary issues integrated include road safety, aviation engineering, noise pollution management, and clean electrical energy.

  Each lesson incorporates a 5-minute Introduction, a 25-minute 4-step Lesson Development phase, a 10-minute Conclusion, Extended Activities, and Teacher Self-Evaluation space. Equipped with worked examples, ticker timers, galvanometers, stopwatches, ripple tanks, and electric bell construction kits, this downloadable Grade 10 General Science Lesson Plans resource is ready for classroom teaching.
