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.
