1. Bell Ringer 04/12/2011 Follow the directions on your Bell Ringer sheet. Weekly Vocabulary: Abiotic Biotic Ecosystem

2. Today� Essential Question: What are the parts that make up an ecosystem? Objective: After viewing a PPT about abiotic and biotic factors, students will be able to identify examples of each by creating a collage with at least 80% accuracy.

4. To meet its needs, a prairie dog must interact with more than just the other prairie dogs around it. An organism interacts with both the living and nonliving parts of its habitat.To meet its needs, a prairie dog must interact with more than just the other prairie dogs around it.

14. Time to Practice You are a scientist who is studying various ecosystems. As part of your research, you need to identify as many BIOTIC and ABIOTIC factors as possible. Using the magazines provided, glue, scissors, and construction paper, make a collage of at least 5 abiotic and 5 biotic factors.
