Storyline Narrative 7.3.3

Standard 7.3.3: Construct an explanation using evidence to explain how body systems have various levels of organization. Emphasize understanding that cells form tissues, tissues form organs, and organs form systems specialized for particular body functions. Examples could include relationships between the circulatory, excretory, digestive, respiratory, muscular, skeletal, and nervous systems. Specific organ functions will be taught at the high school level.

Student Friendly Objective: I can explain how body systems have different levels of organization.

Anchor Phenomenon: Why do organisms such as humans and dogs have organs?

Big Idea: Body systems complete the functions necessary for life

In episode 1, students engage in classroom discussion about the levels of organization of organisms, specifically humans. They will be guided through a discussion by their teacher with a PPT acting as a guide to answer the question, what are you made of? They will use a graphic organizer to keep track of their findings.


Students research and explore the levels of organization in episode 2 using a levels of organization booklet to record their information.


Students will expand their knowledge of the levels of organization by looking further into the organ systems that allow an organism to function and survive. Episode 3 has students elaborate by creating a model of an organ system and constructs an explanation of what the systems does?

Evaluation occurs when students use the assessment to prove proficiency.

Conceptual Understandings

Organisms such as humans have five levels of organization: cells, tissues, organs, organ systems, and organisms.

What are cells, tissues, organs, and organ systems?  


Students participate in a classroom discussion levels of organization.

Episode 2


What are the levels of organization?


Students research information about each level of organization and complete a booklet with their new information.

Conceptual Understandings

Each level of organization performs functions and becomes more complex as we move from cells to the organism.

What do organ systems do? How do they help the organism survive?

Anchor 2

Conceptual Understandings

Each organ system performs a function that supports the survival of the organism.


Students create a model of an organ system and research its function. They share this information with the rest of the class.

Episode 3


What do organ systems do?
