ICSE Class 7 Physics, Unit 1: Physical Quantities and Measurement
From the CISCE curriculum. 7 key concepts, about 3 days of study at 20 to 30 minutes a day.
What this unit aims at
In the earlier classes, teaching-learning emphasised on the measurement of length, mass, time and temperature using devices made for such measurements and how a particular unit and symbol are used to express the result of measurement of each physical quantity. In continuity, this theme aims at enabling children to develop the ability to measure volume and determine the density of a regular solid. They will be introduced to the concept of speed, that contains simple problems to provide an idea of the speed of objects around us and also to know how fast or slow an object is moving.
Your child should be able to
- define volume
- express volume of an object in a proper unit with proper symbols
- measure volume of a liquid using a graduated cylinder and a graduated beaker
- estimate the area of an object of irregular shape using a graph paper
- measure the volume of an irregular solid using a graduated cylinder /a graduated beaker
- define density and write its formula
- express density in a proper unit and symbol
- measure density of a regular/irregular solids
- express result of measurement in a proper unit with proper symbol
- define speed and write its formula
Key concepts in this unit
- Measurement of Volume (3D concept):

- Calculation of Speed:
- Basic Concept Formula Simple Numericals (SI units not required).
Teach this unit at home
- A day-by-day plan from the CISCE concepts, so you know what to cover each day.
- A step-by-step script for each day, so you know what to say and ask (AI-written from the CISCE curriculum, so check it against your child's school book).
- A quiz at the end.
