In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste. Learners dry their tongues with clean paper towels and then taste samples of salt, sugar, crackers, or other dry foods. Use this activity for any lesson on the senses, particularly taste, as well how saliva breaks down chemicals in food.
