Print out a black and white diagram or illustration of the female or male reproductive system. Have students color each section and label them with names and notes. Cut out the parts, and mix them up. Now try to put them back together correctly.
Create a board game with a path from beginning to end. The game will end with a fertilized egg. Create milestones on the path with what happens from sex to conception. Give some of the spaces a question mark. Create cards with different questions concerning reproductive health and have players answer a question when they land on a question mark space. Have each player move his piece, which can be as simple as a bean or glass bead, according to a dice roll. The person who gets to the end wins.
Print out images of reproductive organs and other images for students to learn. Use a glue stick to glue them onto index cards. Write down the name and the details about the image on the back. This is a good game to use to study for a reproductive health test or a class activity if each student creates her own set.
