Mississippi Science HAP.2.2
The Standard
- HAP.2
- Students will demonstrate an understanding of the relationship of cells and tissues that form complex structures of the body.
Construct a model to demonstrate how the structural organization of cells in a tissue relates to the specialized function of that tissue.

What This Standard Means
What Students Need to Do
- Build a labeled model showing how cells are arranged in a tissue. Use the model to explain how that arrangement helps the tissue do its job.
What Mastery Looks Like
- A student can model the thin cell layer in an alveolus and show the short path oxygen takes toward the blood. They can model stacked skin cells and explain how the layers protect tissue underneath.
Common Misconceptions
- Students may draw alveolar walls with several cell layers and claim thicker walls help oxygen move faster. They may draw skin as one layer and miss how stacked cells protect against rubbing.
How to Assess It
- Exit ticket: Sketch an alveolar lining beside a skin surface. Label the cell layers and explain how each arrangement supports gas exchange or protection.
Lesson moves
Ways to Teach It
Build an alveolar lining and a skin surface from paper cells, then label where oxygen moves and where rubbing causes damage.
Ask students to write what would happen if alveolar tissue had as many cell layers as skin.
Give pairs tissue picture cards and function cards to match, then ask them to point out the cell arrangement behind each match.
Show a diagram of lung scarring and ask students to sketch how thicker alveolar walls change oxygen’s path to the blood.
