How can you get help with these changes? • During this time of change students need to be respectful of others 3. Compare Puberty of Boys and Girls (10 min) • Display the Male and Female Puberty Chart • Hand out the Male and female comparison graphic organizer • Have students get into small groups and complete the organizer • Take it up as a class 3. Hygiene (10 min) • Review – during puberty you will start to grow body hair, facial hair, sweat and smell more – pimples will grow • Discuss how proper hygiene is important – take care of your yourself – respect your body Brush your teeth (at least twice a day) Shower daily Bring an extra shirt for PE class Wear a bra (girls) Sanitary napkin also know as a menstrual napkin or pads (girls) – Pads are available at pharmacies and grocery stores and come in a variety of shapes and sizes. Choose pads that are unscented. Pads attach to the inside of underwear by sticky strips. The wings wrap around the leg openings of the underwear. Pads catch menstrual flow. Keep pads in a backpack, locker or bag. Change and dispose of used pads often (wrap in toilet paper and put in the garbage). Wash your face and hands regularly Pantiliners are similar to pads. Used to catch light menstrual flow or vaginal discharge. (Show example)

Discuss the external genitals and internal Reproductive System

External Genitals: Penis • The male external sex organ. • Semen and urine are discharged from the penis. • It is made up of spongy material that fills up with extra blood (becomes erect) when sexually aroused. • There is no bone in the penis. • The penis continues to grow as does the rest of the body. Size varies from person to person. Foreskin • The skin on the end of the penis that retracts during an erection. • This skin may be partially removed in a procedure called circumcision. • Boys who have not been circumcised should cleanse beneath the foreskin of the penis regularly. It is important not to pull the foreskin back if it is still attached to the head of the penis. It will disengage naturally. Circumcision • A procedure to remove the foreskin from the penis conducted by a doctor. • It is usually done soon after birth. • Many boys are circumcised and many are not. It doesn’t affect the function of the penis.

Scrotum • The sac that holds the testicles. • The testicles have to be kept at a certain temperature just below body temperature in order to produce healthy sperm. The scrotum pulls the testicles closer to the body if it is cold and lowers away from the body if it is hot. Anus

• •

The opening at the end of the digestive tract where feces leaves the body. It is not part of the reproductive system, but is part of the digestive system.

Internal Reproductive System: Testicles • The male sex glands. • They are held in the scrotum. • They are on the outside of the body so that they can stay cooler than body temperature for healthy sperm production. • It is normal for one to hang lower. • This is a very sensitive area of the body. It is important to protect the testicles during contact sports, etc. Vas Deferens • This is a narrow tube that carries sperm from the testicles to the urethra. Seminal Vesicles • Two small pouches behind the bladder that produce and store seminal fluid. • This fluid mixes with sperm and other fluid to produce semen. Urethra • Urine and semen pass through this tube to the outside of the body. • Urine and semen cannot come out at the same time. There are two branches to the urethra, one from the bladder and the other from the vas deferens. When the penis is ready to release semen, a valve blocks off the branch to the bladder so urine cannot escape. It is similar to the difference between swallowing and breathing. Air goes to the lungs and food or liquid goes to the stomach even though both substances pass through the esophagus. Bladder • •

The sac that holds the urine produced by the kidney. It is not part of the reproductive system, but the urinary system.

Hand out Male Reproduction Diagram and have students fill it out.

Girls (menstruation discussion) • Introduce menstruation to the girls Explain that menstruation is normal and every girl goes through it, it seems scary in the beginning, but if you are prepared and know what to expect it is something that doesn’t have to be a bad experience • Display the female Reproductive System slide 1 and review key vocabulary (vagina, urethra and anus) • Display the female Reproductive System slide 2 and review key vocabulary (vagina, uterus, ovary, fallopian tube) • Display menstruation slide while you explain Menstruation (period) happens approximately 2 to 2.5 years after a girl’s breasts start growing. About 6 months or so before getting her first period, a girl might notice an increased amount of clear vaginal discharge. This discharge is common. During menstruation, blood comes out of the vagina for 2-7 days, it is different for every girl. Some girls have emotional changes around the time of their periods or experience cramps (pain) in their uterus How does the menstruation cycle work? (refer to menstruation slide) 1. Eggs (ovum) are found in the ovaries 2. one egg is released to the fallopian tube each month 3. the egg travels along the fallopian tube and attaches to the wall of the uterus (endometrium) 4. when the egg is not fertilized, the outside wall of the uterus sheds and leaves the vagina as blood 5. period happens 6. the cycle continues every month Play Interactive video When a female is having her period she places a pad or sanitary napkin inside her underwear to protect her clothing. Pads should never be flushed down the toilet, wrap in toilet paper and throw it in the garbage.

5. Question Box • Read and answer questions with the students (if the students do not write many questions you can read some from the Grade 5 Boys or Girls Common Questions • Have students fill out another slip for next class
