Middle Grades – Grade 7 Science Middle Grades – Grade 7 Science As the cell is often called the building block of life, it is critical for students to understand the parts of the cell in order to build upon this knowledge to understand animal and plant life. You are charged with developing a unit on cells, tissues, organs and organ systems. Some topics you’ll want to include are: How cells take in nutrients, grow and multiply Cell structures and their functions, including cell membrane, nucleus, cytoplasm, chloroplasts mitochodria The hierarchy of cell organization (cells form tissues, tissues form organs, and so on) The purposes of the major organ systems of the human body (digestion, respiration, reproduction, circulation, etc.) Georgia Performance Standards S7L2. Students will describe the structure and function of cells, tissues, organs, and organ systems. Learning Objectives: Assessments: At the conclusion of this lesson, the student will be able to: 1. Explain that cells take in nutrients in order to grow and divide and to make needed materials 2. Relate cell structures (cell membrane, nucleus, cytoplasm, chloroplasts, mitochondria) to basic cell functions. 3. Explain that cells are organized into tissues, tissues into organs, organs into systems, and systems into organisms. Explain the purpose of the major organ systems in the human body (i.e., digestion, respiration, reproduction, circulation In a homework assignment, the student will explain in writing how cells take in nutrients in order to grow and divide. A rubric will be provided and students will need to provide a thorough explanation, using their textbook as their primary source. The student will match the cell structures to the basic cell functions in an online matching exercise created in Hot Potatoes The student will create a diagram of the flow of cells to organisms in an in-class activity using the smartboard. In the essay portion of the exam, the student explain how the purpose of the major organs systems. A grading rubric will be provided inside of the exam.
