1) Measurement, Units & Physical Quantities (Core)

• Base & derived quantities: length, mass, time, area, volume, density.
• SI units: m, kg, s, N, J, W, Pa, C, V (as introduced progressively).

• Compute heat energy transferred and interpret ΔT sign.
• Read heating curve graphs: identify plateaus and slopes.

2) Electricity & Magnetism (Core Grade 10 Theme)

• Current, voltage, resistance: I, V, R and relationships (Ohm’s law where appropriate).
• Series vs parallel circuits: current/voltage distribution and equivalent resistance.
• Electrical power: P = VI and energy usage over time.
• Magnetic fields: field lines, solenoids, electromagnets (basic).
