These 6 high school level activities include a worksheet on how chemicals affect a developing fetus and a lab that compares the growth rates between males and females. Students draw developing fetuses to scale, determine their personal position on birth control and they determine the costs associated with having a baby up through one year old. In another lab, students measure then graph the length and mass of a developing fetus. Test and Quizzes for this unit are available on this website. Corresponding lecture notes are free and can be found on this website.
