• Hierarchy of Organization – 4 days (includes intro)

Unit Driving Questions:

Ohio Standards**

  • How do scientists learn and communicate? 
  • How are the basic concepts, skills, and understandings in science related to one another? interrelated? 
  • How are atoms, molecules, cells, organs, and organ systems organized and interconnected?   


  • Hierarchy of Organization
  • Types of Tissues
  • Homeostasis
  • Anatomical Terminology


  • Cells are made of atoms, which are organized into molecules and biological molecules, which are organized into the complex structures which make up cells.  Organelles are an example.
  •  Organelles have specific functions, sometimes working together.
  • Cells of the same type are organized into tissues.
  • Tissues, working together, make up an organ.
  • Different organs, working together, make up an organ system.
  • Organ systems interact, making it possible for the human body to function.

Learning Targets**

  • State the hierarchy of organization in living things, starting with the atom and building to a human and continuing to the biosphere.
  • Describe each link in the hierarchy and explain why it holds the position in the hierarchy that it does.
  • Locate on a diagram or model the relative positions, body sections, and divisions of the abdominopelvic cavity.
  • Locate on a diagram or model regional body part terms used in medicine.
  • Demonstrate how to use medical prefixes, root words, and suffixes to create and translate medical terms.
  • Summarize the eleven major body systems, functions, organs, and organ functions.




  •  Hierarchy card sort and definitions – include populatio­­­­­n, community, ecosystem, biome
  • Blood cells in solutions microscope activity


  • Sketch a picture of each link (level) and describe.
  • Record in group on whiteboard and then in individual notes.
  • Quiz: description, placement, and rationale for each level
  • Sketch diagrams of RBCs in each solution and explain each diagram.

Visions into Practice: Classroom Examples

Designing technological/engineering solutions using science concepts

Demonstrating science knowledge

Interpreting and communicating science concepts

Recalling accurate science


  • Research various species of organisms that have been studied in order to understand fundamental physiological processes in humans. Explain the considerations in determining what species is the best to study for a particular process.
  • Analyze data about various human cell types and hypothesize the relationships between structure and function.


  • Identify the levels of organization from cellular to organism.
