Mississippi Science L.4.1.3
The Standard
- L.4.1
- Students will demonstrate an understanding of the organization, functions, and interconnections of the major human body systems.
Construct models of organ systems (e.g., circulatory, digestive, respiratory, muscular, skeletal, nervous) to demonstrate both the unique function of the system and how multiple organs and organ systems work together to accomplish more complex functions.

What This Standard Means
What Students Need to Do
- Build a model of a body system and label what its organs do. Show how that system works with another, such as the lungs supplying oxygen to blood that travels to muscles.
What Mastery Looks Like
- A student can trace oxygen from the lungs through blood vessels to a working muscle. They can explain that the lungs move oxygen into blood and the heart pumps blood through vessels.
Common Misconceptions
- Students may say the heart makes oxygen or that lungs pump blood. Some draw oxygen going straight from the lungs to muscles, without traveling in blood.
How to Assess It
- Give students a blank body outline. Ask them to draw lungs, a heart, blood vessels, and a leg muscle, then add oxygen arrows and write what the lungs and heart each do.

Ways to Teach It
Use a paper body outline, cutout lungs and heart, and yarn blood vessels to model oxygen moving from lungs to muscle.
Ask, 'Why can't the heart alone deliver oxygen to a running leg?' Have pairs explain what the lungs and blood vessels do.
Give pairs cards labeled windpipe, lungs, heart, blood vessels, and muscles; have them sort by system and connect the cards with oxygen arrows.
After walking up stairs, count breaths and pulse beats, then use the model to explain why both rates rise.
