7Fertilization A sperm cell joins with an egg cell Gamete + Gamete = ZygoteSperm = male reproductive cellsEgg = female reproductive cellsEmbryo = Early stage of pregnancy (sesame seed)Fetus = Human embryo at week 9
8Fertilization Fertilization If the Egg Isn't Fertilized If one sperm does make its way into the Fallopian tube and burrow into the egg, it fertilizes the egg. The egg changes so that no other sperm can get in. At the instant of fertilization, your baby's genes and sex are set. If the sperm has a Y chromosome, your baby will be a boy. If it has an X chromosome, the baby will be a girl.If the Egg Isn't FertilizedIf no sperm is around to fertilize the egg, it moves through the uterus and disintegrates. Your hormone levels go back to normal. Your body sheds the thick lining of the uterus, and your period starts.
9Hormones Male Sex Hormones- Female Sex Hormones- Testosterone produced in testes-affects the production of sperm and signals certain physical changes at puberty, such as the growth of facial hairFemale Sex Hormones-Estrogen & progesterone produced by ovariesEstrogen- activates certain physical changes at puberty, controls the maturation of eggsProgesterone- activates changes to a woman’s reproductive system before and during pregnancy
10Endocrine Gland: Female A brain structure called the hypothalamus causes the nearby pituitary gland to produce certain chemicals, which prompt the ovaries to produce the sex hormones estrogen and progesterone.Prompted by the hypothalamus, the pituitary gland releases follicle stimulating hormone (FSH) during ovulation
11Endocrine Gland: MaleHypothalamus signals the pituitary gland to release two hormones- Luteinizing hormone (LH) and follicle- stimulating hormone (FSH)LH triggers testes to begin making testosteroneTestosterone and FSH then trigger the production of sperm
12Puberty: Role PlayingStudents will chose an event that occurs to an male or female during puberty. Students will work together to develop skits that accurately depict the situation and role play the skit in front of the class.Examples of situations:What it feels like when a girl gets her period for the first timeHow a boy feels when he his voice cracks when he's delivering a talk at schoolHow it feels to have a bad facial blemish right before going to a big social eventWhat it feels like as awareness of the opposite sex increasesHow a girl feels when she can't go to a swim party because she has her periodHow the smallest boy in the class feels as he watches his peers shoot up
13Rubric Each group will be graded by a rubric based on the following: Three points: showed strong research skills- all information completely accurate; answered all the questions correctly; showed maturity and insight into the topic while working with a group in preparing and presenting a skit; participated actively in class discussions.Two points: showed on-grade research skills- some information is accurate; answered most of the questions correctly; worked well with a group while preparing and presenting a skit; was somewhat engaged in class discussions.One point: showed below grade level research skills- information is not accurate; answered two questions correctly; had trouble working with a group while preparing and presenting a skit; was not engaged in class discussions.
