Model practical write-up

2   Chemical Earth (syllabus)

2.1 The living and non-living components of the Earth contain mixtures.

2.2 Although most elements are found in combinations on Earth, some elements are  found uncombined.

2.3 Elements in Earth materials are present as compounds because of their interactions at the atomic level.

2.4 Energy is required to extract elements from their naturally occurring sources.

3   Metals (syllabus)

3.1 Metals have been extracted and used for many thousands of years.

3.2 Metals differ in their reactivity with other chemicals and this influences their uses.

3.3 As metals and other elements were discovered, scientists recognised that patterns in their physical and chemical properties could be used to organise the elements into a Periodic Table.

3.4 For efficient resource use, industrial chemical reactions must use measured amounts of each reactant.

3.5 The relative abundance and ease of extraction of metals influences their value and breadth of use in the community.

4   Water (syllabus)

4.1.  Water is distributed on Earth as a solid, liquid and gas

4.2  The wide distribution and importance of water on Earth is a consequence of its molecular structure and hydrogen bonding.

4.3 Water is an important solvent

4.4 The concentration of salts in water will vary according to their solubility, and precipitation can occur when the ions of an insoluble  salt  are in solution together

4.5  Water has a higher heat capacity than many other liquids

5   Energy (syllabus)

5.1 Living organisms make compounds which are important sources of energy.     

5.2 There is a wide variety of carbon  compounds.   

5.3 A variety of carbon compounds is extracted from organic sources.  

5.4 Combustion provides another opportunity to examine the conditions under which chemical reactions occur.

5.5 The rate of energy release is affected by factors such as types of reactants.
