II. Learning Content III. Learning Procedure IV. Evaluation V. Assignment

Through a group presentation about the hormones of the body, the students should be able to:

A. explain the role of the hormones involved in the body;

B. describe the feedback mechanism involved in regulating the processes in the human body;

C. locate the different organs of the Endocrine system; and

D. name the hormone or hormones produce by the Endocrine organs.

C. Materials:LCD Projector

D. Concepts:1. Hormone- influences activity of cells in another part of the organism.2. The organs of the Endocrine system include: hypothalamus, pineal gland, pituitary gland, thyroid gland, parathyroid gland, thymus gland, pancreas, adrenal gland and the gonads.

A. Preparation*Preliminary AssessmentFrom the pictures given below, identify which does not belong to the group and write an explanation why the organ should not be included in the group.

Heart- The heart is a part of the circulatory system, while all the rest are parts of the nervous system.

(See last page) Recently, athletes tested positive for anabolic steroids have been barred from engaging in sports. Make a poster to inform people of the effects of these substances.

D. Skills: 1. Explaining the role of hormones in the body. 2. Describing the feedback mechanism.

Lungs- the lungs are a part of the respiratory system while the rest are parts of the female reproductive system.

Skull- the skull is a part of the skeletal system, while the rest are parts of the endocrine system.

Intestine- the intestine is a part of the digestive system, while the rest are parts of the male reproductive system.

B. Presentation1. Post a diagram of the Endocrine system and its parts.

2. Define what a hormone is.

3. Present the different Endocrine glands and their hormones.

Hormone- secreted by the endocrine glands into the blood stream which carries them throughout the body.

4. Based from the presentation on the endocrine glands and their hormones, ask a student to give a short inference about the endocrine system.

5. Let the students study the pictures below, identify the name of the endocrine gland and explain its effect according to its function.

The endocrine system consists of glands that secrete chemical known as hormones to control various body processes. This control system usually brings about slow changes in the body because chemical messengers move more slowly than nerve impulses. The major glands in the body are the pituitary, thyroid, parathyroid, thymus, adrenal, pancreas, ovaries and testes.

6. Describe the feedback mechanism of the endocrine system.

7. Ask a student to identify the endocrine gland based on its projected location.

1. Ovaries- secrete more progesterone and estrogen to promote pregnancy. 2. Adrenal gland- produces adrenaline to activate short-term stress response. 3. Pituitary gland- produces growth hormones4. Thymus gland- secretes thymosin to stimulate production of T-cells to fight against infection. 5. Pancreas- secretes insulin that regulates blood sugar levels.

C. Application1. Group the class into 7 with 6 or 5 members each. 2. Ask them to research about a certain hormone and its effect to the body. 3. Each group will be given 2 minutes to present. 4. A scale of 1-5 will be given as a score based on their creativity.

D. GeneralizationWhat is the coordinative function of the Reproductive and Endocrine systems?

Evaluation:MATCHING TYPE. On a ¼ sheet of pad paper, match the Endocrine glands on Column A with its location on Column B and identify on Column C one hormone that the gland secretes. (14 pts)

Answer Column A Column B Column C1. Pancreas A. On top of the kidneys 8. 2. Parathyroid B. Between the kidneys 9. 3. Thymus C. Below the voice box 10. 4. Thymus D. In the neck 11. 5. Adrenal E. Lower abdomen 12. 6. Ovary F. In front of the heart 13. 7. Testes G. Beneath the brain 14.

Hormones secreted by the endocrine system play an important role in both male and female reproductive systems. The pituitary gland controls the functions of both the testes and the ovaries. These hormones keep the reproductive system properly functioning.
