Once satisfied that sufficient information has been collected, teachers may make judgments about students' demonstration of outcomes. Typical demonstrations of this module's intended outcomes are provided here to give teachers an indication of the pattern of behaviour to look for when making judgments. Science and Society 6.3 Students use scientific concepts to evaluate costs and benefits of applications of science. Life and Living 5.3 Students evaluate consequences of interactions which occur between the living and non-living parts of environments. Catchments A catchment area or basin is land that is bounded by natural features such as hills or mountains and from which all runoff water flows to a low point.
Catchment areas vary in size and make-up.
Large catchment areas, such as those drained by the Fitzroy and Burdekin Rivers, are bordered by mountain ranges and include major drainage networks of creeks and rivers. Large catchment areas are made up of hundreds of smaller 'sub-catchment areas'. These may be bordered by low hills and ridges and drained by only a small creek or gully. A range of natural resources and land uses will be found in a catchment area from the headwaters to the mouth of the river or lake, but these may vary greatly. What happens in one part of a catchment is likely to affect the well-being of other parts of the catchment.
