Grade: 7th Science: Unit 2: Living Organisms
Time Frame: October 21 – December 20
(37 Days)
Unit Description and Student Understandings: This unit focus is on the life cycle of plants and animals, including humans, and on the comparison of
complete and incomplete metamorphosis. Representative organ systems are explored. The unit concludes by introducing students to the development and use of
dichotomous keys. Plants and animals go through defined stages of development. Students will explore metamorphosis in animals as a specific example and
investigate life cycles of some plants. Evolutionary adaptations of each life form should be understood and observed by students as much as possible. In studying
the characteristics of living organisms, students should recognize similarities and differences and be able to construct a dichotomous key for identification of
species and defined groups. This unit will focus on the major functions, organs and interactions of body systems. The student will understand the components and
functions of body systems and how they work together to keep us alive.
Guiding Questions:

3.
4.
Can students classify organisms using a dichotomous key?
Can students describe complete metamorphosis and incomplete metamorphosis citing examples of each?
Can students describe and compare life cycles of selected plants and animals and compare these to the human life cycle?
Can students identify major organs in the human body, relate their structure to their function, and describe the interaction with the system?
