ICSE Class 8 Chemistry, Unit 2: Physical and Chemical Changes
From the CISCE curriculum. 2 key concepts, about 1 day of study at 20 to 30 minutes a day.
What this unit aims at
This theme will enable children to understand that there are different types of changes in our surroundings which as slow/fast, reversible/irreversible, periodic/non-periodic and physical/chemical. In physical changes, no new substance is formed while in chemical change, a new substance with properties different from the element forming that substance is formed. Learning of these changes will also help in developing different scientific skills amongst them.
Your child should be able to
- illustrate different changes occurring in nature with examples learned in previous classes
- perform some activities to show some well-known changes
- differentiate between physical and chemical changes and classify the changes
Key concepts in this unit
- Revise and review the topic on Physical and Chemical Changes taught in earlier classes.
- Physical and Chemical changes – Classification with examples.
