Learning Objectives

Indicator: B6.1.2.1.1 - Know the general properties of metals such as lustre, malleability, conductivity and ductility

By the end of the lesson, learners can:

Identify common metal and non-metal objects found in their homes, schools and communities.
Define the four general properties of metals: lustre, malleability, conductivity and ductility.
Classify given objects as metals or non-metals by testing or observing their properties.
Explain, with reasons, why a particular object is classified as a metal or a non-metal.
Demonstrate, using simple materials, how the property of conductivity can be used to distinguish metals from non-metals.

Exemplars (from the NaCCA curriculum)

- Learners, in groups, gather different objects such as ruler, erasers, exercise books, comb, plastic bowls, connecting wires, cups, plates, cooking pans, roofing sheets, iron nails, pins, etc.
- Learners classify the various materials as metals or non-metals based on the following properties: lustre, malleability, conductivity and ductility.
- Learners give reasons for their classification.
- Relate the lesson to everyday activities that involve the use of metals.
- Given a piece of aluminium foil and a drinking straw, learners describe how they will use conductivity to classify them as metals or non-metals.
- Learners design and make simple machines with metals.
