| Day 1 |
| Topic 20-1 The Endocrine System |
| Objectives Describe how the endocrine system controls body processes. Identify the endocrine glands. Explain how negative feedback controls hormone levels. Define hormones. Explain some of the jobs of hormones. |
| State Goals |
Classwork-Homework
On the BoardEndocrine Gland: produce and release their chemical products into the blood stream Hormone: chemical product of an endocrine gland; speed up or slow down organs Target Cell: recognize the hormone's chemical structure Hypothalmus: link between the nervous and endocrine systems Pituitary Gland: regulates growth, blood pressure, and water balance Negative Feedback: system is turned off by the condition it produces

| Topic 20-2 Male and Female Reproductive System |
| Objectives Describe the female reproductive system. |
| State Goals |
| Classwork-Homework
On the Board Egg: female sex cell Sperm: male sex cell Fertilization: joining of the egg cell and sperm cell Zygote: fertilized egg Testis: produce sperm Testosterone: hormone controls development of male physcial characteristics Scrotum: pouch of skin holds testis Semen: mixture of sperm cells and fluid Penis: organ semen leaves body from Ovary: produce eggs Estrogen: hormone controls female characteristics Fallopian Tube: passageway for eggs Uterus:egg attaches to this organ Vagina: birth canal Menstrual Cycle: female reproductive system Ovulation: process by which egg is released Menstruation: extra blood and tissue that pass out of the body if the egg is not fertilized

| Topic 20-3 The Human Life Cycle |
| Objectives Describe the process by which an embryo develops into a fetus. |
| State Goals |
| Classwork-Homework
On the Board Embryo: the developing human from 2 cells to 8 weeks Fetus: 9th week until birth Amonitic Sac: fluid-filled membrane around embryo Placenta: link between the embryo and the mother Umbilical Cord: ropelike structure of blood vessels between the fetus and the mother Adolesecence: stage of development when children become adults Puberty: period of sexual development when the body becomes able to reproduce

Body Quest Group activity to create a presentation about one of the body's
systems. 10 different systems. Presentation planner could be an individual
asignment. |

| Levels of Organization In unicellular (single-celled)
organisms, the single cell performs all life functions. It functions independently.
However, multicellular (many celled) organisms have various levels of organization within
them. Individual cells may perform specific functions (causing a division of labor) and
work together for the good of the entire organism. The cells become dependent on one
another. Explore Cells, Tissues, Organs, Organ Systems, and Organisms. |
