Date: Week 31
Lesson Duration: 45 minutes
Week & Period: Week 31, Period 6
Topic: Matter and Molecules
Sub-topic: Definition of matter, states of matter, molecules, solutions, and separation methods
Learning Objectives
By the end of the lesson, students should be able to define matter, identify its states, explain the meaning of molecules, prepare simple solutions, and describe basic separation methods.
Previous Knowledge
Students already know that matter exists in different forms and that some substances can dissolve in water.
Instructional Materials
Samples of solids, liquids, and gases, salt and water, beakers, filters, sieves, charts, markers.
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Ask learners to name things they see around them and classify them as solid, liquid, or gas. Demonstrate dissolving salt in water and ask learners what happens.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Learners’ Activities (Expanded):
- Students handle real-life examples of solids (stone, book), liquids (water, juice), and gases (air in a balloon).
- In small groups, they prepare simple solutions by dissolving salt or sugar in water.
- Learners attempt separation activities:
- Filtration: separating sand from water using filter paper.
- Evaporation: leaving saltwater to dry so salt crystals remain.
- Sieving: separating rice from sand using a sieve.
- Students record observations and share group findings.
- Teacher explains matter, molecules, solutions, and methods of separation with live demonstrations and simple experiments.
Assessment Checks:
- Teacher asks learners to:
- State the form of matter for a given object (solid, liquid, or gas).
- Give one example of a molecule.
- Explain which separation method is suitable for salt + water, sand + water, and rice + sand.
- Learners respond orally and in writing.
Notes (Expanded & Detailed):
- Matter: Anything that has mass and occupies space. It can be seen, touched, or felt.
- Examples: Solid (rock, wood, chair), Liquid (milk, oil, water), Gas (oxygen, carbon dioxide, air).
- Molecules: The smallest particle of matter that still has its properties.
- Examples: A drop of water contains many water molecules (H₂O), oxygen molecule (O₂), carbon dioxide molecule (CO₂).
- Solutions: A mixture where one substance dissolves in another.
- Examples: Sugar in water, salt in water, milk in tea.
- Separation Methods:
- Filtration: used to separate an insoluble solid from a liquid (sand + water).
- Evaporation: used to recover dissolved solids from solutions (salt from saltwater).
- Sieving: used to separate particles of different sizes (stones from rice).
- These activities help learners understand that matter is made of molecules, can mix to form solutions, and can be separated back into components using simple scientific methods.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Recap states of matter, molecules, how to prepare solutions, and methods to separate mixtures.
Evaluation Method (Expanded)
Exit slip/quiz: Students write one state of matter and one method of separation. Teacher collects slips and provides oral feedback.
Assignment (Expanded): Prepare a solution at home and describe how it could be separated.
Follow-up Activity: Observe and list examples of solids, liquids, and gases around the home or school.
Differentiation / Inclusive Strategies: Use visual aids, hands-on demonstrations, and simplified explanations for learners needing extra support.
