# 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

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.
