Title: Biomes & Ecosystems
Subject: Science-Living Environment
Grade Level(s): 6-8
Students will discuss the manners in which a geographic environment affects life and then create a list of various types of environmental settings, or ecosystems that exist on earth. The class will then discuss biomes and be divided into small working groups. Each group will research a virtual expedition into a certain eco-regions of the world. Groups will study each expedition and how life is affected by that region. Students will then make groups presentations on their findings and discuss ecological threats to their region.
Students will understand and apply scientific concepts, principles, and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science
Lesson Goals: Students will work in cooperative learning groups to identify and describe various biomes/ecosystems on Earth. Students will utilize the Internet to conduct research on the particularities of each biome and how life varies in different biomes. Ecological problems and hazards facing each biome will also be addressed.
Groups will be assigned one of the virtual expedition sites listed below. Each site provides information on a real expedition that was conducted. These sites thus provide visitors with a "virtual expedition" into that region. Each group should visit their expedition site to gather information and obtain links. Groups should record not only information regarding their expedition, but also information about the ecosystem in which their expedition took place, and life in it. Groups should conduct their research with the goal of creating a report that summarizes their expedition, the biome represented, and how life is affected in that region. Students are encouraged to make contrasts with the initial brainstorm list that was made on how life is affected by the biome in which it inhabits.
Anticipatory Set: Students will be asked to brainstorm about ways in which their geographic environment affects their life. They should be encouraged to describe manners in which a geographic environment different from theirs would affect their life and other life forms. A separate brainstorm should then be done listing various types of environmental settings, or ecosystems that exist on earth. Biome should then be introduced and defined. A discussion contrasting and comparing lifestyles in varying biomes can be encouraged. Students should then be divided into small working groups. Group size to be determined by class size and computer availability, as each group will require use of a computer.
