Subject: Chemistry
Lesson Topic: Deduce the symbol equation with state symbols for a chemical reaction, given relevant information
Learning Objective/s:
  • Describe the purpose of state symbols in chemical equations.
  • Write correct chemical formulas and assign appropriate state symbols.
  • Balance symbol equations using coefficients while keeping subscripts unchanged.
  • Apply a systematic procedure to produce a balanced equation for given reaction descriptions.
  • Check the final equation for correct atom balance and appropriate state symbols.
Materials Needed:
  • Projector or interactive whiteboard
  • Chemistry textbook or handout on state symbols
  • Worksheet with practice reactions
  • Set of chemical formula cards
  • Whiteboard markers and erasers
  • Online simulation link (optional)
 Introduction:
Begin with a quick recall of how chemical formulas represent substances and why state symbols are important. Ask students to name common state symbols they have seen. Explain that today they will learn a step‑by‑step method to write balanced symbol equations and will be assessed through a short exit ticket.
Lesson Structure:
  1. Do‑Now (5') – students write the state symbols for a list of given compounds on the board.
  2. Mini‑lecture (10') – review of state symbols and balancing basics, using the projector.
  3. Guided practice (15') – work through the magnesium‑CO₂ example together, modelling each step.
  4. Pair activity (15') – students complete two practice questions, checking each other with a checklist.
  5. Whole‑class feedback (10') – discuss common errors and reinforce the procedure.
  6. Independent practice (10') – remaining practice question as an exit ticket while the teacher circulates.
Conclusion:
Summarise the five‑step procedure and emphasize checking both atom balance and state symbols. Students submit their exit ticket showing one balanced equation. For homework, assign three additional reactions from the textbook to practice.
