SECTION: CHEMISTRY
MODULE: 2
Part A: Units
Simple classification of substances
a. Effects of heat on substances
b. Constituents of matter
c. Application of separation techniques in extraction of substances
Part B: Project
Observe heat effects and practice separation techniques.
Project Title: Heat Effects and Separation in Daily Life
Objective: Observe effects of heat and apply separation techniques using common materials.
Project Instructions:
- 1. Choose a household substance and observe changes when heated (safe method).
- 2. Identify components of a simple mixture.
- 3. Apply a separation technique (filtration, evaporation, or decantation).
- 4. Record observations and conclusions.
- 5. Consult your coach where necessary.
Evidence to Submit:
- • Observation notes.
- • Separation steps used.
- • Final outcome and explanation.
Submission
Part C: Training Others

Guidance:
- • Explain one separation technique and why it works.
- • Demonstrate a safe example.
- • Ask the learner to describe the process.
Reflection:
- • What did the learner grasp quickly?
- • What was challenging?
- • What support do you need from your coach?
