| Subject: Chemistry |
| Lesson Topic: State the formulae of the elements and compounds named in the subject content |
Learning Objective/s:
- State the correct chemical formulae for elements, simple binary compounds, common acids, bases and salts.
- Distinguish between ionic and covalent formulas using charge‑balance and bonding rules.
- Apply formula‑writing rules to unfamiliar compounds in short written tasks.
|
Materials Needed:
- Projector or interactive whiteboard
- Chemistry textbook / IGCSE syllabus handout
- Printed worksheets with formula tables
- Periodic table posters
- Whiteboard and markers
- Answer key for teacher
|
Introduction:
Begin with a quick quiz on element symbols to activate prior knowledge. Explain that today’s focus is converting names of substances into correct chemical formulae, a key skill for the IGCSE exam. Outline the success criteria: students will accurately write formulas for elements, binary compounds, acids, bases and salts.
|
Lesson Structure:
- Do‑now (5’) – students write symbols and atomic numbers for a set of elements.
- Mini‑lecture (10’) – review ion charges, ionic vs covalent bonding, and formula rules using the projector.
- Guided practice (15’) – teacher models writing formulas for examples (NaCl, CO₂, H₂SO₄) while students follow on worksheet.
- Collaborative activity (15’) – groups complete a worksheet covering elements, binary compounds, acids, bases and salts; teacher circulates.
- Whole‑class check (10’) – groups share answers, teacher clarifies common errors.
- Independent practice (10’) – students attempt the practice list (5 compounds) and record answers.
- Exit ticket (5’) – each student writes one formula for a compound not covered and the rule used.
|
Conclusion:
Summarise the charge‑balance and bonding principles that guide formula writing. Collect exit tickets as a quick retrieval check. For homework, assign a set of eight named compounds for students to write the correct formulas.
