What This Standard Means
What Students Need to Do
- Students trace lymph from body tissues through lymph nodes and back to the blood. They explain how different white blood cells fight germs and what lymph nodes, bone marrow, and the spleen do.
What Mastery Looks Like
- Given an infected finger cut, a student can trace lymph to an armpit node and explain why the node might swell. They can say that neutrophils engulf germs, B cells make antibodies, and the spleen filters blood rather than lymph.
Common Misconceptions
- Students may think lymph is a white blood cell rather than fluid that carries cells. They may think all white blood cells make antibodies, or that the spleen filters lymph.
How to Assess It
- Exit ticket: A finger cut becomes infected, and an armpit node swells. Explain what lymph carries, what happens at the node, and how neutrophils and B cells respond.
Lesson moves
Ways to Teach It
Give pairs a body outline, blue yarn, and organ labels; have them trace lymph from a finger cut through an armpit node to blood.
Ask why an armpit node might swell after a finger cut; have students write two sentences naming lymph and a white blood cell.
Give groups neutrophil, B cell, lymph, node, and spleen cards; read function clues and have students raise the matching card.
Show a vaccine appointment card; ask students to sketch how lymph carries vaccine material to a node where B cells begin a response.
