This book presents six lessons on reproduction and birth specifically designed for middle and junior high school students. The lessons are designed to appeal to young students' needs and interests about the subject matter. This module uses discussions and worksheets to explain how the genetic make-up, reproduction process, and gestation period for humans is different from other animals. Illustrations, tables, charts and transparency masters make the lessons easy to follow. Lessons also offer critical, age-appropriate information about inherited and acquired traits, prenatal development, the stages of birth, developmental disabilities, and birth disorders. The book: (1) provides transparency masters that illustrate fetal development and birth; (2) identifies ways some developmental and birth disorders can be prevented; (3) reinforces good health practices; (4) offers alternate teaching strategies for advanced and younger students; and (5) includes methods for evaluating students' knowledge and understanding of material presented.
