ICSE Class 8 Physics, Unit 2: Physical Quantities and Measurement
From the CISCE curriculum. 5 key concepts, about 2 days of study at 20 to 30 minutes a day.
What this unit aims at
Previous learning demonstrated the measurement of the density of regular solids. In this class children will develop the ability to measure the, density of an irregular solid and also of a given liquid. They will also understand that due to the difference in the value of densities of a solid and liquid, a piece of solid can float or sink in a liquid.
Your child should be able to
- measure density of an irregular solids
- measure density of a liquid
- discuss the concept of floatation based on relative densities of solid and liquid
- express result of measurement in proper unit with proper symbol
- solve simple numerical problems based on formula of density
- compare densities of matter in three states, solid, liquid and gas
- make careful observations including measurements
- gather data using formal units
- make conclusions from collected data
- make predictions using scientific knowledge and effectively communicating the same
Key concepts in this unit
- Measurement of Density of irregular solids using:
- Eureka Can Measuring Cylinder
- Measurement of Density of Fluids:
- Basic Concept Concept of Floatation and sinking of a substance (relate to density)
- Comparison of densities in the three states of matter.
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.
