The purpose of this model is to demonstrate the natural phenomena of acid molecules eroding the enamel of an individuals tooth. Through this lesson students will identify pH levels of common acidic foods and drinks. Student will also determine the significance of saliva to the maintenance of pH of the mouth. Students will discover that the longer acidic molecules are exposed to the enamel of a tooth the percentage of healthy enamel on a tooth decreases. When healthy enamel is eroded, dentin is exposed, which gives teeth a yellow appearance. Students will use the model to compare the relation of acidic beverages to the percentage of healthy enamel.
