ICSE Class 7 Chemistry, Unit 5: Language of Chemistry
From the CISCE curriculum. 8 key concepts, about 3 days of study at 20 to 30 minutes a day.
What this unit aims at
Chemistry involves the study of a large number of elements and compounds that also have been learnt earlier with their representation by their short hand notations i.e. symbols and formulae. This theme will enable children to understand that it is not convenient to write the full names of the elements and compounds, and the use of symbols has made the job of the chemists much easier. In addition, they will further realize that Chemistry also involves the occurrence of a large number of chemical reactions that are written in the form of equations known as chemical equations. The writing of chemical equations involves writing of reactants and products as their symbols and formulae. Thus symbols and formulae have also made writing of chemical equations in Chemistry very convenient.
Your child should be able to
- identify the names of reactants and products of different chemical reactions
- write a chemical reaction in the form of a chemical word equation
- recognize the usefulness of a word equation
Key concepts in this unit
- Chemical reactions A chemical reaction may take place when two or more reactants come in contact with one another and transfer of energy takes place.
- Characteristics of occurrence of a chemical reaction:
- Change of:
- Colour State Smell Evolution of gas
- Precipitate formed Heat evolved / released
- Chemical Equations:
- Writing word equations for chemical reactions and emphasize on the observational skills and the names of products formed
- Some examples of word equations for practice.
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.
