Cnidarians, Ctenophora, or Coelenterates?

 The Biology Co-op class is tackling Zoology with extensive comparative morphology by phyla: Porifera, Cnidaria, Arthropoda, Nematoda, Annelida, Mollusca, Platyhelminthes, Echinodermata, and Chordata.  Here is an excellent comparison chart.  The next phylum is Cnidaria.  Cnidarians and Ctenophores are Coelenterates and are now treated as two different phyla rather than part of Phylum Coelenterata.  Here is a good, introductory slideshow.  Here is the coloring worksheet we’re using for paper dissections.  During class, the kids are creating charts, making detailed paper dissections, and crafting clay models.
