What This Standard Means
What Students Need to Do
- Students research a viral infection, an autoimmune disorder, an immunodeficiency disorder, and lymphoma using reliable health sources. They explain what drives each condition and trace its effects on immune defenses and the body.
What Mastery Looks Like
- A student can explain how infection, an attack on the body's own tissue, loss of immune function, and cancer of lymphocytes differ. They can use evidence to explain why HIV raises the risk of other infections and why lymphoma may enlarge lymph nodes.
Common Misconceptions
- Students may think every swollen lymph node means cancer, or that HIV infection and AIDS are the same stage. Some confuse an autoimmune disorder, which attacks the body's own tissues, with immunodeficiency, which weakens defenses against infection.
How to Assess It
- Exit ticket: Compare HIV infection and lymphoma in three lines. Name what drives each condition, which immune cells are affected, and one effect on the body.

Ways to Teach It
Use colored counters to model HIV reducing CD4 cells, then draw how fewer helper cells leave the body less able to fight infections.
Give students NIH fact sheets on influenza, lupus, HIV, and lymphoma; ask them to write one cause-and-effect sentence for each.
Have pairs match four condition cards to cards describing their causes and effects, then explain each match.
Read a clinic handout on swollen lymph nodes and explain why that symptom alone cannot tell someone whether they have an infection or lymphoma.
