Think about last summer when you were playing baseball. You were hot and sweaty. How did you smell? (yucky) You were able to take care of the problem by taking a bath or shower. You need to wash your hair and brush your teeth. These things are necessary for personal hygiene. Today, we are going to learn about the importance of proper hygiene.

Classroom Connector One

Hygiene refers to the cleanliness of the body. A clean body is a healthier body. Let's first talk about cleaning our teeth. Explain the proper way to brush and floss and how often to visit the dentist. Define the following:
1. Gingivitis - a painful disease which can cause permanent destruction your teeth and gums.

2. Cavity - holes in teeth caused by decay.

3. Plaque - a sticky film of bacteria that is harmful to your teeth.

4. Fluoride - a chemical that helps to prevent tooth decay.

(Students will cut out pictures of five healthy foods for teeth and five foods which are harmful to teeth.)

Classroom Connector Two

(Arrange for a dental hygienist to visit class to demonstrate proper brushing and flossing techniques.)

Classroom Connector Three

Hair care is our next topic. Keeping your hair clean will make you look and feel better. Wash your hair as often as needed. Don't forget to wash your brushes and combs. These should be as clean as your hair. Don't share your brushes or combs with anyone.

(Lower your voice to a mysterious whisper.) Hair has an enemy lurking in schools. It is disgusting, silvery, oval shaped, crawling, and it lays eggs. What is it? (Lice) You should not ignore head lice because IT CAN HAPPEN TO YOU! Anyone can get head lice.

Head lice are very contagious. They travel from one head to another on brushes, combs, sports helmets, scarves and coats.

It is no shame to get head lice. But the doctor or the health department will recommend the proper treatment.

(A barber or cosmetologist would be an excellent guest speaker for hair care.)

Classroom Connector Four

Get into the daily habit of taking a bath or shower. Your skin needs to be kept clean. You should wash each day with soap and water. Soap can break down the oils that are on your skin. It helps remove dirt that is trapped in these oils. It also washes away extra oil, germs, and dead skin cells.

Skin has two main parts. The outer part of your skin is called the epidermis. Touch your skin now. You are feeling the epidermis. Underneath the epidermis is the inner part of the skin called the dermis. The dermis has nerves and other tissues. When you take a bath, old skin cells are being washed off the surface of your skin. Think of a time when you went on a camping trip with your family or a time when you were not able to take your bath when you normally do. How did you feel? How did your skin feel? Your epidermis was dirty and the pores of your skin were clogged with sweat and germs. How do you think that we get new skin cells if we wash off old dead ones? New cells are constantly forming in the epidermis. These new cells push up and replace old skin cells.

Make arrangements for a dermatologist or a skin consultant to speak to the class and provide skin demonstrations. (Possibly free samples of cleansers and moisturizers could be give to the class.)

(Materials needed: 2 small clear containers, 1 medicine dropper, cooking oil, liquid soap, spoon)

Procedure: A. Fill a container three-fourths full with cold water. Add three drops of oil with medicine dropper. Move the jar gently in a circular motion. What happened to the oil? (response) How does the oil look? (response) B. Next add three drops of soap to the oil and water. Stir with a spoon. What happened to the oil? (response) C. Now, empty the container. When container is empty, fill three fourths full with warm water. Now add three drops of oil to the warm water. Does the oil look any different in warm water than it did in cold water? (response) D. Finally, add three drops of soap to the oil and warm water. Stir with a spoon. What has happened to the oil? (response)

I want you to answer the following questions:

1. What happened to the oil when it is mixed with the water?

2. How did the soap break up the oil?

Students will keep a PERSONAL hygiene checklist such as the one below for at least one week. Afterwards, they will write a brief report on improving personal hygiene. (Their personal experience as well as data from guest speakers and reference books should be used as sources for the reports.)

Vocabulary List for Hygiene Lessons:

Hygiene Gingivitis Plaque Fluoride Floss

Epidermis Dermis Barber Cosmetologist

Tell your neighbor why good hygiene is important. Choose one of these professions: dentist, dental hygienist, barber, cosmetologist to write a report about.

1. Students will be grouped into groups of four or five. They will brainstorm ideas which promote good hygiene and health for 15 minutes. A group-appointed secretary will record thoughts.

2. Students will transform the group ideas into a Health Skit. Each group member will be assigned a character name such as "Fabulous Flossie" or "Super Skin" - the smoothest super hero around. Allow 30 minutes for the group to crystallize their skit and title it.

3. Performance day. Each group will share their health play.)
