A suggested script is in italics. Feel free to modify the script to your style and your students’ needs. 1. Discuss the purpose of the lesson. Identify the lesson as, primarily, a review of information that many students learned in earlier grades. Explain that being well-grounded in knowledge about the reproductive system will help them make sense of discussions later in the unit about pregnancy, birth control, and sexually transmitted diseases. Also, if they have health problems in the future, knowing body parts helps them explain to a health provider what they think the problem may be. 2. Brainstorm with the class about body parts. Write on the board in three columns: Male / Female / Both. Ask students to name reproductive system body parts, both internal and external, in the three columns. Fill in from the Teacher Master List (below) the parts that students don’t mention. As you list the parts on the board, briefly define each body part, where it is in the body and what it does. 3. Use Reproductive System Visuals 1-6 to continue reviewing the male and female reproductive systems, including the location and function of each part. Use a document camera (or SMART Board, overhead projector, etc) to project the images on the board. Explain that the parts labeled as male, female, or both are for most people, but when people are intersex (i. e. , they have a disorder of sex development), there may be some differences †¦ differences that were present at birth. NOTE: Briefly review â€Å"what it does† (each part’s function, below) if students are unfamiliar with the physiology, as you point to the visuals. Please do not feel that you must convey every bit of information in the Teacher Background chart, below. Find more suggested language regarding the hymen and circumcision in Lesson 16, p 5.
