Classification Card Sort

The attached file contains 20 cards, each displaying an organism. The organisms cover all 5 kingdoms and 3 domains.
I have used this as an introductory activity when teaching about classification. The idea is to get the pupils thinking about how organisms are classified and why there are often disagreements. It is also a good starting point for discussions into limitations of the 5 kingdoms and why the three domains system is more frequently used by scientists today.
The cards include 7 prokaryotes, 4 animals, 3 plants, 3 fungi and 3 protoctists. Of the 7 prokaryotes, 4 are archaebacteria and 3 are eubacteria. The cards only provide pictures and species name and so there is not really enough information for pupils to determine which are archaebacteria and which are eubacteria. However, pupils can be given the hint that many archaebacteria live in extreme environments - this will help them to identify which are which.
