Chapter 9 study guide and vocabulary

Dear parent:

The following is the study guide students will be completing for the chapter 9 science test. I am sending a copy home for you to use as resource to help your student prepare for the test. Please take time throughout our unit to review the information with your student. I have also included the vocabulary words for this chapter. It is very important that your student be able to define those words. If you have any questions please contact me. ~Mrs. Scholten
