## Stage 6 Skills

**HSC Exam**

Make sure that you bring:

- 360 degree protractor - this will be easier to use than a 180 degree protractor.

- a couple of coloured pencils - in case you have to do any mapping. Coloured pencils will enable you to do maps much more quickly than having to device patterns to show difference between different items.

- ruler

string for measuring distance

eraser

- Board allowed calculator (you should already have one of these for your maths exam)

magnifying glass - not absolutely necessary, but might come in handy if you have to try to see very small symbols on a topographic map, or to see more detail on photographs.

**Students learn to interpret maps by:**

• calculating the gradient of a slope as a ratio

• calculating the vertical exaggeration of a cross-section

• determining sight lines between two points

• constructing a transect between two points and describing the changes along it

• identifying spatial interaction and change using a variety of sources

• describing patterns, relationships, networks, linkages and evidence of change within and between regions or areas

• determining the density of a specific feature on a map

• reading, constructing and interpreting choropleth maps

• recognising the key features of changing pressure patterns on weather maps

• designing and interpreting flowcharts.

**Students learn to analyse graphs and statistics by:**

• calculating the rate of increase or decrease between two points

• estimating the value of proportional circles of different size using a key

• estimating the value of particular segments in pie graphs of different size

• identifying the three elements depicted in a ternary graph and the line scale of each

• stating the ‘mix’ of elements at any point on a ternary graph

• identifying clusters and patterns on a ternary graph

• constructing and interpreting proportional divided circles

• interpreting frequency distributions and diagrams

• reading and interpreting logarithmic and semilogarithmic graphs

•

**Students learn to interpret photographs by:**

• orientating a photo to a map

• estimating the scale of aerial photographs and satellite images

• estimating the time of day at which a photograph was taken

• calculating areas of land use as a ratio

• identifying spatial associations, interactions and change

• constructing a precis map from an aerial photograph or satellite image

• using Geographic Information Systems (GIS) to examine spatial and ecological issues.

Skills from previous years are also assessable. Make sure that you also revise these skills. They are assumed knowledge. A quick overview of some of the junior topographic skills is found below.
