Introduction to classification
Taxonomy is the branch of science concerned with
classification. This video (4:11) shows how classification works
using a red fox as an example.
Classification systems continue to evolve so
there is some debate about the number of categories. The following
screenshot from the previous video is a reminder that there are
generally considered to be eight categories involved in biological
classification as follows:
An interactive resource is available from the UNE Discovery program (https://www.unediscoveryvoyager.org.au/latin-taxonomy-build-a-character/) where students can make adaptations to creatures and then use the Latin binomials to name the new creatures.
Introduction to dichotomous keys
How many groups could the following five shapes be grouped into?
Try sorting them into groups of 1, 2, 3, 4 and 5.
Discuss the word 'criteria' and then link it to
classification in terms of 'attributes'.
