The APES Unit 9 Review can be used several ways:

• While going through a Unit as a working document, a learning guide, students can add to it as they read though the text book or listen to lecture
• To complete just before a Unit test as a study guide
• At the end of the semester to prepare for the AP Environmental Science Exam

When used as a learning guide: It is helpful to have students begin the Unit by going through the Essential Knowledge itself, highlighting key vocabulary.  This gives them a good foundation to grow from, they know what to look for and what is important as they learn about, or review for the Unit.

When my students use these as review, I put them into small groups of three or four. They work together to complete the questions. Then students get into new groups and review their answers. I help guide them and help with questions that they can not come to an agreement on.
