Human Body Systems

Fifth graders meet the teams of organs that keep a body running, from the bones that hold it up to the lungs that bring in air, and match each system to the job it does.

Exit Ticket

Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.

QUESTION 1
Which body system moves the body, and how?
The muscular system, by pulling on the bones of the skeleton.
QUESTION 2
How do the respiratory and circulatory systems work together?
The lungs take in oxygen and the blood carries it to the rest of the body.
QUESTION 3
What is the main job of the digestive system?
To break down food so the body can use it for energy and growth.

Create: a body systems map.

Have students draw a body outline, label three systems, and write the job each one does, so the organs become teams with clear roles. A printable body-systems worksheet is in the Science library.
