(c) Drawing

The ability to:

(i) make clear, accurate line representations of specimens, with no shading or
unnecessary details;

(ii) produce illustrations with clean continuous lines of even thickness;

(iii) label illustrations accurately and use label lines which do not cross each other
or carry arrowheads or dots;

(iv) annotate illustrations appropriately and accurately;

(v) make illustrations which are large enough to display specific details; and,

(vi) calculate the magnification of the illustrations.

Note: A drawing is used to illustrate a three-dimensional representation of a specimen
whereas a diagram illustrates the surface view of a section cut through the
specimen.

(d) Planning and Designing

The ability to:

(i) identify problems, make predictions, develop hypotheses and devise means
of carrying out investigations to test the hypotheses;

(ii) plan and execute experimental procedures and operations in an appropriate
sequence;

(iii) use experimental controls where appropriate;

(iv) modify an original plan or sequence of operations as a result of difficulties
encountered in carrying out experiments or obtaining unexpected results;

(v) take into account possible sources of errors and danger in the design of an
experiment; and,

(vi) select and use appropriate equipment and techniques.

Planning and Designing skills may be assessed through the use of fieldwork.
