Embedded Core Skills:

• Observation
• Classification
• Critical thinking
• Communication

Learning Materials:

• Objects made of metals and non-metals
• 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:

1. Classification of Non-Living Things:
   Non-living things can be classified into metals and non-metals.
2. 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.
3. 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.
4. 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.
