Score The student will: 3.0 compare the biodiversity of organisms in different types of ecosystems (e.g., rain forest, grassland, desert) noting the interdependencies and interrelationships among the organisms in these different ecosystems The student exhibits no major errors or omissions. 2.5 No major errors or omissions regarding 2.0 content and partial knowledge of the 3.0 content Score There are no major errors or omissions regarding the simpler details and 2.0 processes as the student: given an ecosystem, describes the biodiversity of organisms found there However, the student exhibits major errors or omissions regarding the more complex ideas and processes. 1.5 Partial knowledge of the 2.0 content but major errors or omissions regarding the 3.0 content Score With help, a partial understanding of some of the simpler details and processes and 1.0 some of the more complex ideas and processes. 0.5 With help, a partial understanding of the 2.0 content but not the 3.0 content Score Even with help, no understanding or skill demonstrated. 0.0 EALR 4: Life Science Big Idea: Ecosystems (LS2)
