1 Overview Overview Do human interactions with ecosystems have a negative or positive effect on biodiversity? Do human interactions with ecosystems have a negative or positive effect on biodiversity? by Misty Wade As a connection to previous studies of systems in nature the four week intensive study and knowledge gained of the biotic and abiotic features in ecosystems,5 major biomes and their classes,importance of biomes, how biomes have changed during the history of life on earth, human activities that have drastically altered these communities, and how conservation and preservation of biomes should be a major concern to all, students are analyzing causes for the changes in biodivierstiy that are occurring today in several regions across the globe. Students are reading,annotating,studying, and discussing journal/periodical articles, educational websites, population graphs,illustrations,editorial cartoons,and conducting hands on activities, to allow them to better understand the events happening around world. After the students are comfortable with the topic they, will then, write an argumentative essay, using their chosen texts, to support their stand on the positive or negative side of the unit s essential question.

3 Section 1: What Task? TEACHING TASK Task Template 2 [3 Levels] Argumentation & Analysis L1: Do human interactions with ecosystems have a negative or positive effect on biodiversity? After reading informational texts write an essay that addresses the question and support your position with evidence from the text(s). L2: Be sure to acknowledge competing views. L3: Give examples from past or current events or issues to illustrate and clarify your position. STUDENT BACKGROUND According to the Glencoe Science text, an ecosystem consists of all the organisms living in an area, as well as the nonliving parts of that environment. Biodiversity refers to the variety of all forms of life in an ecosystem, biome or an entire planet. As the world's human population increases, we are having increased interactions with our environment. You will be using information gathered and knowlege gained from your reading of various text resources to argue the negative or positive effects human interactions have on biodiversity.
