Description

Use this set of 2 homework assignments on "The Phyla Porifera and Cnidaria" to provide your students with quality homework assignments for your invertebrate units. Both printable and digital versions are included. This resource contains 12 student pages consisting of 131 questions. As I teach my units on these phyla, I assign a portion of these questions for homework each night. The completed homework assignments provide a thorough study guide for the unit test. You can also use a few questions during class each day to check for student understanding of the concepts being taught.

You can use these homework assignments with the Porifera/Cnidaria chapter of any biology textbook.
