ICSE Physics Class 7 Syllabus

The syllabus consists of seven themes - (i) Physical Quantities and Measurement, (ii) Force and Pressure: Motion, (iii) Energy, (iv) Light Energy, (v) Heat, (vi) Sound, and (vii) Electricity and Magnetism.

Theme 1: Physical Quantities and Measurement

Measurement of Volume (3D concept)

Concept of unit volume

Measurement of Area

  • Estimate the Area of irregular shape using a Graph paper

Measurement of Density of regular solids

  • Basic concept
  • Formula
  • Simple Numericals (SI units not required)

Calculation of Speed

  • Basic Concept
  • Formula
  • Simple Numericals (SI units not required).

Theme 2: Force and Pressure: Motion

Motion as a change in position of an object with respect to time.

Types of motion

  • Translatory
  • Circulatory
  • Oscillatory
  • Repetitive (Periodic and Non Periodic)
  • Random

Uniform and Non Uniform Motion: concept of distance and speed (average speed)

Weight

  • Concept
  • Differences between Mass and Weight.

Theme 3: Energy

Energy

  • Energy as capacity to do work.
  • Units of energy (joule and calorie).
  • Different forms of energy.
  • Inter-conversion of energy

Law of Conservation of Energy

  • Real world examples.

Theme 4: Light Energy

Reflection

  • Definition and Examples.
  • Terms related to reflection - normal, plane, point of incidence, angle of incidence, angle of reflection.
  • Laws of Reflection.

Plane mirror

  • Uses.
  • Ray Diagram (no mention of virtual image). Characteristics of the image formed (Lateral Inversion, same size, distance is preserved).

Speed of light (3 x 108 m/s).

Primary colours (RGB).

Formation of secondary colours by colour addition.

Appearance of colour of an object (based on reflection and absorption)

Colour subtraction

Theme 5: Heat

Heat as a form of energy and its units, joule (J) and calorie (cal).

Different units of Temperature (°C, °F, K).

Effects of Heat

  • Change in Temperature.
  • Change in Size (Expansion and contraction).
  • Change in State.
  • Good Conductors and Bad Conductors of Heat and their examples.
  • Choice of conductors and insulators in day to day life (Pan handles, metal cooking utensils etc.)

Methods of Heat Transfer

  • Conduction
  • Convection
  • Radiation

Thermos Flask: (Application of Heat Transfer)

  • Construction
  • Working

Theme 6: Sound

  • Sources of sound.
  • Sound as a longitudinal wave.
  • Characteristics of a sound wave: Amplitude (Relate amplitude with loudness) and Frequency.
  • Sound needs a medium to propagate.
  • Reflection and Absorption of sound.
  • Relative speed of sound in different mediums.

Theme 7: Electricity and Magnetism

  • Law of Magnetism
  • Test for a magnet (by repulsion)
  • Electromagnetism, Electromagnets and their applications - Electric bell
  • Electric current as a flow of charges
  • Electric cell as source of electricity
  • Resistors as components that oppose the flow of current.
  • Symbolic representation of electrical components (key, battery, bulb, conducting wire, resistor)
  • Simple electric circuit - Series and Parallel
  • Battery as a collection of cells connected in series.
  • Good and Bad conductors of electricity.
