Mississippi Science HAP.11.3
The Standard
- HAP.11
- Students will investigate the structures and functions of the lymphatic system, including the cause and effect of diseases and disorders.
Compare and contrast the body’s non-specific and specific lines of defense, including an analysis of the roles of various leukocytes: basophils, eosinophils, neutrophils, monocytes, and lymphocytes.

What This Standard Means
What Students Need to Do
- Students compare fast, broad defenses with responses that target a particular germ and remember it. They explain the jobs of basophils, eosinophils, neutrophils, monocytes, and lymphocytes.
What Mastery Looks Like
- A student can explain how skin and inflammation protect the body before a targeted response develops. They can match basophils with histamine release, eosinophils with parasite defense, neutrophils with engulfing bacteria, and monocytes with becoming macrophages. They can explain how B and T lymphocytes target germs and form memory.
Common Misconceptions
- Students may think every white blood cell makes antibodies, when that is a job of B lymphocytes. They may also think inflammation targets one germ or that fast, broad defenses create the same lasting memory as a targeted response.
How to Assess It
- Exit ticket: Match basophils, eosinophils, neutrophils, monocytes, and B lymphocytes to histamine, parasites, engulfing bacteria, macrophages, and antibodies. Then explain why a vaccine can help months later but skin protects right away.

Ways to Teach It
Give pairs cards labeled skin, swelling, neutrophils, monocytes, B cells, and T cells; have them order the defenses after a contaminated cut.
Ask: Why might a scraped knee swell before matching antibodies appear? Write two sentences using basophils and B cells.
Run a cell-role matching race with cards for the five leukocytes and their jobs; have partners explain one match they found tricky.
Show a flu shot reminder beside a scraped-knee photo; have students label targeted immune memory and fast, broad protection.
