Phylum Echinodermata
Introduction: Today you will be investigating various aspects of the
phylum Echinodermata. You will be moving from station to station to
observe, think and answer questions about many animals in this
phylum as well as comparing and contrasting with animals from the
previously discussed phyla. Throughout the activity, you may use any of your notes in your note
packet to guide you.
Station 1- Symmetry game
Directions: To begin, log onto the wiki (hess.wiki.conestogavalley.org) and click on the
INVERTEBRATES link. Once there, download the slideshow that is entitled, Name that
Symmetry! Look at the pictures shown in the slideshow and determine whether they are showing
asymmetry (no symmetry), bilateral symmetry (one way to cut it for a mirror image), or radial
symmetry (multiple ways to cut it for a mirror image). When you have determined your answer,
write the type of symmetry on the corresponding number line below.

Station 4- Compare and Contrast
Directions: This unit we have learned about a variety of different animals starting with sponges
and moving all the way through until the current topic of echinoderms. For this activity, you
may use notes that you have taken as well as you may look at all of the specimens in the front of
the classroom. You must choose one of the other phyla we discussed and compare it to the
phylum Echinodermata. The phyla you may choose from are: Porifera, Cnidaria,
Platyhelminthes, or Nematoda.
1.) Are echinoderms more complex or simpler than the phylum you chose?

2.) Why do you think that?
