Background Information:
The students should have a basic knowledge of dental hygiene and foods that protect their teeth. |
Lesson Procedures:
- Read to the students a dental health-related book, such as Let's find out about Toothpaste by Kathy Barabas; Open Wide: Tooth School Inside by Laurie Keller; or Barney Goes to the Dentist by Linda Cress Dowdy.
- The students will discuss which foods promote tooth decay and the importance of correctly brushing teeth regularly.
- Use a plastic model of teeth to demonstrate the proper way to brush teeth. Invite a dentist to class to demonstrate proper tooth brushing and to conduct the experiment.
- Show a picture of a human skeleton and note that teeth are part of the skeletal system. The class will begin the tooth decay experiment below.
Tooth Decay Experiment
- Put soft drink containing phosphoric acid (such as cola), vinegar, and water into three separate cups.
- Drop a tooth or cooked chicken wishbone into each cup.
- Check daily to observe changes. Discuss how these changes might be prevented in our own mouths.
- In a science observation journal, keep records of observations.
- The students will visit the American Dental Association Web site and discuss how sugar can cause tooth decay. (Natural sweeteners, such as honey and fruit juice, can cause tooth decay).
- Make the healthy snack below.
Yogurt/Fruit Dip
- 8 ounces plain low-fat yogurt
- 1/3 cup frozen orange juice concentrate
- 1/8 teaspoon cinnamon
Blend ingredients until mixed. Store in refrigerator until it is used. This dip is especially good with bananas and apples.
- Talk with the students about how different teeth in the mouth have different purposes (tearing meat, chewing and grinding, etc.)
- Show a model of teeth and tell the function of each.
- Talk about how scientists can tell what dinosaurs ate by looking at their teeth: for example, "sharp tooth" was a meat eater (carnivore) and dinosaurs with flat teeth were plant eaters (herbivores). Other animals, like humans, ate both plants and animals (omnivores).
- Ask the students to illustrate one dinosaur and a food the dinosaur ate.
- Sing the following song to the tune of Row, Row, Row Your Boat:
Brush, brush, brush your teeth
Brush them twice a day.
Brush them in the morning time
And at your bedtime, too.

STUDENTS WITH SENSORY IMPAIRMENTS
VISION
1. Use large print versions of books listed in
(Procedure 1) and use enlarged version of
skeleton used in (Procedure 4)
2. Use screen magnifier to view American Dental
Association Kid's Section on website.

Explorations and Extensions:
- Each student will tell a healthful snack story using the title "My Favorite Snack." Each student will illustrate his/her story.
- The snack stories above will be used to decorate the school cafeteria.
- Keep track throughout the school year of how many teeth are lost each month. At the end of the year, the teacher will enter all of these data into a spreadsheet with the students helping to determine the necessary data from the "Lost Tooth Chart." A bar graph will be made using these data, and the students will compare and contrast this graph to the "Lost Tooth Chart."

Reflections:
This lesson fits well into dental health month in February. Tooth decay can be caused by eating too much incorrect foods and not brushing regularly. If sugars remain on the teeth without being removed, tooth decay can form. It is important to eat properly and to brush teeth after meals and snacks.
We have differently shaped teeth for different types of eating. The flat teeth in the front, the sharp canine teeth, and the flat-surfaced back teeth serve different purposes. The flat-back teeth are for chewing and grinding the food. The canine teeth are for ripping meats similar to the way dogs (canines) do. The flat, thin front teeth are for tearing or biting foods. All of these teeth are important for the normal eating behavior of omnivorous animals such as humans. When people do not take care of their teeth properly, they could lose their teeth and their normal eating patterns. |
