Life's Greatest Miracle

Viewing Ideas

Before Watching

1. Review the male and female human reproductive systems with students and examine how the systems function.

2. As students watch, have them take notes on which systems and body parts develop in each phase of the developmental process.

After Watching

1. Draw a 40-week timeline on the chalkboard. Ask volunteers to fill in the timeline using their notes about each stage of embryonic/fetal development.

2. Genetic and environmental factors influence both male and female reproductive systems. Have students brainstorm some of the positive and negative environmental influences on sperm production and pregnancy, including nutrition, exercise, and exposure to chemicals.
