Module 1 | The chemical Earth

Focus 2: Although most elements are found in combinations on earth, some elements are found uncombined

Lesson 1 | Classifying elements

  • Classify elements as metals, non-metals and semi-metals according to their physical properties.

  • Analyse information from secondary sources to distinguish the physical properties of metals and non-metals.

Lesson 2 | Elements and the Periodic Table

  • Process information from secondary sources and use a Periodic Table to present information about the classification of elements as:
    – metals, non-metals and semi-metals
    – solids, liquids and gases at 25˚C and normal atmospheric pressure

  • Explain the relationship between the reactivity of an element and the likelihood of its existing as an uncombined element.

Lesson 3 | Investigating the properties and uses of elements

  • Plan and perform an investigation to examine some physical properties, including malleability, hardness and electrical conductivity, and some uses of a range of common elements to present information about the classification of elements as metals, non-metals or semi-metals.

  • Account for the uses of metals and non-metals in terms of their physical properties.
