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.
