Characteristics of good models
Models qualify to be good if they have these qualities:
(1) They are three dimensional with depth, height and width providing interior views of the objects which are normally covered or otherwise invisible.
(2) They are large enough to be seen readily by the whole class.
(3) They are well-finished.
(4) They make use of color and texture to highlight important features. Parts which are not essential should be in less conspicuous colors.
