Name: Denise Ward Grade level: 7th Subject: Science Time: 40 minute period Objective: Describe the three major types of interactions among organisms Topics/Content to be covered: Competition, Predation, and Symbiosis New York State Learning Standards: SC7.6.2 Describe how living things depend on the living and nonliving environment for their survival. Relationships among organisms may be competitive, harmful, or beneficial. Materials and equipment needed for lesson activities: Video clips at www.pbs.org/nature Methods of assessment: Beginning of lesson- Students predict the ecological relationship among seven pairs of animals During lesson- Students will name the actual relationship after watching a video clip showing many interactions End of lesson- In pairs, students relationships. will act out the five ecological Learning Activities and Organizational Patterns: Introductory activities: Notes and examples of ecological relationships Competition: The struggle between organisms to survive as they attempt to use the same limited resources. Predation: When an organism feeds on another organism Symbiosis: is a close relationship between two species where at least one of the species is helped (benefits). Relationships can be competitive, harmful, or beneficial Mutualism: Both species benefit Commensalism: One species benefits while the other is neither helped nor harmed Parasitism: One organism lives on or in another organism and harms it Developmental activities: Students must predict the relationship between two animals. They will watch a clip that shows and describes the relationship. Students must decide the relationship for each clip. As a class, we will go over the activity Concluding activities: Act out each interaction with a partner. Each student will write the definitions and give examples of the relationships from memory in their science journals. Students may consult a partner or their notes.
