The key to success in teaching a unit on ecology is to provide good instruction followed by a good review exercise.
This document is a 5 page student worksheet consisting of 53 questions. As I am teaching my unit on community ecology, I assign a portion of these questions for homework each night. This document provides quality homework assignments and ends up being a completed and thorough study guide for the unit test. This worksheet of homework questions and problems was written to go along with my Powerpoint on this same topic: Community Ecology PPT and Notes
All answers are included in the additional 3 page teacher guide that is included with this product.
PLEASE NOTE: This product is also included in my Community Ecology Complete Lesson Plan Bundle
The questions are of varying difficulty levels. Question types include compare and contrast, fill in the blank, short answer, multiple choice, and true/false. Many of the questions are basic and concrete in nature, but many of the questions involve critical thinking and problem solving skills.
Your download will include both a Word document as well as a pdf of this extensive homework/study guide.
This study guide is appropriate for any biology or life science class with students in grades 7 - 12.
