Set Induction:
Show students a metal spoon and a plastic spoon, then ask them to describe the differences in appearance, weight, and feel.
Entry Behaviour:
Students already know the difference between living and non-living things.
Learning Resources and Materials:

- Pictures of different metal and non-metal materials
Reference Books:
- Lagos State Scheme of Work
- Basic Science Textbook for JSS 1
Instructional Materials:
- Metal objects like iron, copper, and aluminum
- Non-metal objects like wood, plastic, and rubber
- Charts showing the properties of metals and non-metals
Content:
- Classification of Non-Living Things:
Non-living things can be classified into metals and non-metals. - Metals:
- Definition: Metals are hard substances that can conduct electricity and heat.
- Examples: Iron, copper, aluminum, gold, and silver.
- Properties of Metals:
- Good conductors of electricity and heat.
- Solid at room temperature (except mercury).
- Shiny and can be polished.
- Malleable (can be hammered into thin sheets).
- Ductile (can be drawn into wires).
- Uses of Metals:
- Iron is used for making gates and construction materials.
- Copper is used for electrical wiring.
- Aluminum is used to make cans and airplane parts.
- Non-Metals:
- Definition: Non-metals are substances that are not as hard as metals and cannot conduct electricity or heat.
- Examples: Wood, plastic, rubber, sulfur, and carbon.
- Properties of Non-Metals:
- Poor conductors of electricity and heat.
- Can be solid, liquid, or gas.
- Dull and brittle (break easily).
- Not malleable or ductile.
- Uses of Non-Metals:
- Wood is used for making furniture.
- Plastic is used for making bottles and containers.
- Rubber is used to make tires.
- Importance of Metals and Non-Metals:
- Metals are important for construction, manufacturing, and technology.
- Non-metals are useful in making everyday items like furniture, containers, and tires.
