Mississippi Science HAP.11.6

ScienceGrades 9–12Human Anatomy and Physiology

The Standard

HAP.11: Students will investigate the structures and functions of the lymphatic system, including the cause and effect of diseases and disorders.

Investigate various forms of acquired and passive immunity (e.g., fetal immunity, breastfed babies, vaccinations, and plasma donations).

Teacher's field guide

What Students Need to Do: Students trace where protective antibodies come from in a fetus, a breastfed infant, a vaccinated person, and someone given antibody-rich donor plasma. They explain who made the antibodies and whether the person's own immune system builds memory.
What Mastery Looks Like: A student can identify infection and vaccination as active immunity, and antibodies from the placenta, breast milk, or donated plasma as passive immunity. They can explain why borrowed antibodies act quickly but fade, while active immunity can build memory.
Common Misconceptions: Students may think vaccines contain ready-made antibodies or that a fetus makes the antibodies it receives through the placenta. They may also think breast milk gives permanent protection or that donating plasma makes the donor immune.
How to Assess It: Exit ticket: A baby receives antibodies through the placenta, a teen gets vaccinated, and a patient receives antibody-rich donor plasma. For each, name who makes the protective antibodies and whether the recipient builds immune memory.

Lesson moves

Give pairs cards labeled placenta, breast milk, vaccine, and donated immune plasma; have them move paper antibody cutouts from each maker to each recipient.
Ask: Why might a vaccinated teen stay protected longer than a newborn receiving antibodies through the placenta? Require the words memory cells.
Play four corners labeled natural active, medical active, natural passive, and medical passive; read cases about infection, vaccination, breast milk, and donated plasma.
Show a hepatitis B exposure plan listing plasma-derived immune globulin and vaccine; ask why the patient receives both.
