Ecosystem+Review-+Forest

=Unit Title: Ecosystem Review- Forestry= Grade level: 11-12 Subject Area: Modern Consumer Science Unit Designer: Cinda Murray Time frame: 4 weeks =Pennsylvania Environment & Ecology Standard:= 4.6.10A Explain the biotic and abiotic components of a an ecosystem and their interactions. 4.6.10B Explain how cycles affect the balance in an ecosystem. 4.6.10C Analyze how ecosystems change over time. 4.3.10.A. Evaluate factors affecting the use of natural resources. 4.3.10.B. Analyze how humans manage and distribute natural resources. 3.1.12.A1. Relate changes in the environment to various organisms’ ability to compensate using homeostatic mechanisms. =Performance Indicators / Objectives:=
 * • Students will compare the interactions of biotic and abiotic components in an ecosystem.
 * • Students will analyze the effects of abiotic factors on specific ecosystems.
 * • Students will describe how the availability of a resource affects organisms in the ecosystem.
 * • Students will explain energy flow in a food chain through an energy pyramid.
 * • Students will explain trophic levels.
 * • Student will evaluate the efficiency of energy flow in a food chain.
 * • Students will explain how erosion and sedimentation have changed the quality of soil related habitats.
 * • Students will explain the concept of carrying capacity in an ecosystem.
 * • Students will interpret possible causes of population fluctuations.
 * • Students will examine and explain how organisms modify their environments to sustain their needs.
 * • Students will identify a specific environmental impact and predict how what change may take place to affect homeostasis.
 * • Students will identify the major biomes and explain their similarities and differences.
 * • Students will assess the effects of latitude and altitude on biomes.
 * • Students will describe an element cycle and its role in the ecosystem.
 * • Students will explain the consequences of interrupting natural cycles.
 * • Students will identify causes of succession.
 * • Students will identify and explain the succession stages in an ecosystem.
 * • Students will analyze the consequences of interrupting natural cycles.
 * Students will collect and record data using a 100ft tape, compass and protractor.
 * Students will calculate the diameter of a tree from a measured circumference.
 * Students will create a to scale map of their forest study plot.
 * Students will document observations using a digital camera.
