No Saliva, No Taste?
For grades 3-12
In order for food to have taste, chemicals from the food must first dissolve in saliva. Once dissolved, the chemicals can be detected by receptors on taste buds. Therefore, if there is no saliva, you should not be able to taste anything. To test this theory, dry your tongue with a clean paper towel. Once your tongue is dry, try tasting a few samples of salt, sugar or other dry foods. Rinse your mouth and dry your tongue after each test.
Materials:
👉Food items - sugar, salt, crackers and other dry food
👉Clean paper towels
👉Water (for rinsing in between tests)
