Don't worry I'll protect you from the Typo Police!
Its FLASH to the rescue!!!

Coelenterate, Sponge
and Worm Phyla
Study Guide
by Mr. Carrison (Ok, and some help from the Typo Police)
Gates Intermediate School - Scituate, MA

The following was pieced together from two study guides so there may be some duplication.

As always, caution as this blog has not as yet passed the scrutiny of the Gates division of the dreaded
Typo Police!

Use this study guide wisely. I hope you are entering into your notes any information you are unsure of after attempting to answer some of the questions found below. Trying to answer the questions below is an excellent way to test your knowledge on what you will find on Wednesday’s test. After this test we will probably have only two more tests before the term closes. Let's finish up strong!
