The language of chemistry in the ICSE syllabus.

ICSE introduces chemistry in Class 6 and the language of chemistry with it — the names and symbols of the first twenty elements. Word equations follow in Class 7 and formulas in Class 8, but valency, the formulas of radicals and the balancing of equations are not taught until Class 9.

Classes covered
Classes 6 to 9
Chemical formulas

Chemical equations
Set by theme rather than enumerated
Writing a formula is taught
Class 8, Theme 5 — formulas of compounds, and chemical equations from word equations
Balancing is taught
Class 9, Theme 1 — valency, the formulas of radicals, and balancing

The gap. A student writes symbols in Class 6 and balances equations in Class 8, three years and one year respectively before Class 9 explains valency and how a formula is put together.

Class 6

Theme 2 — The Language of Chemistry

Chemistry is introduced as a subject. Students learn the full names and the symbols of the first twenty elements of the periodic table, and are introduced to the language of chemistry itself.

Class 7

Theme 5 — Chemical Equations

Writing word equations for chemical reactions.

Class 8

Theme 5 — Language of Chemistry

Symbols of elements, formulas of compounds, chemical equations written from word equations, and the balancing of chemical equations.

Class 9

Theme 1 — Language of Chemistry

The symbol of an element, valency, the formulas of radicals, valency and the formulas of compounds, chemical equations and their balancing.

Questions

When does ICSE introduce chemistry?
In Class 6, together with the language of chemistry: the full names and symbols of the first twenty elements, under Theme 2.
When does ICSE teach a student to balance a chemical equation?
Balancing is set in Class 8 under Theme 5, and taught again in Class 9 under Theme 1 alongside valency and the formulas of radicals.
Does the Council say students find this difficult?
The Pupils Performance Analysis, which the Council publishes every year, identifies writing symbols, chemical formulas and balanced chemical equations as a persistent difficulty. The 2002 analysis for Class 10 chemistry recommended that teachers introduce innovative methods to help students remember formulas and equations.

This is the gap the Playbook was written for.

The Language of Chemistry, Playbook® teaches the alphabets first — thirty elements and twenty-five radicals as punch-out tokens — then formulas, then balanced equations, in that order and with a score gate at each step. It is the order the tables above are set in and the order the textbooks explain last.

The other boards

  • CBSE — Classes 7 to 10 · Formulas and equations both appear from Class 7. Writing a formula is explained in Class 9 and balancing in Class 10.
  • SSLC — Classes 8 to 10 · The order is inverted. Balancing an equation is explained in Class 8, before either a chemical formula or a chemical equation has been explained.
