MENSTRUATION: HOW DOES IT WORK?
This unit lays the foundation for future units (e.g.,
SPERMATOGENESIS: HOW DOES IT birth control methods, HIV prevention, STI prevention, etc.) and will prepare students to conduct the "Puberty Education: When It's Time to Change" workshop with younger audiences.

Purpose:
 A pre-test helps students focus on the subject and appreciate what they need to learn

 Students fill out pre-tests and put aside to correct and discuss at the end of puberty instruction. Young women should Exercise helps to reduce avoid heat and swimming unpleasant symptoms of and reduce the amount affects a woman's menstruation for some that they exercise during ability to think.
