MouthScience Kit:  Power of pH Lesson

Our  MouthScience® Power of pH Lesson provides 3rd through 6th grade students with an engaging, hands-on experiment that demonstrates the levels of acid and sugar contained in common drinks. The purpose of the exercise is to motivate students to make intentional and healthier drink choices that will decrease their chances for cavities and gum disease.

Our free MouthScience® Kit provides educators with everything they need to conduct the lesson. This instructional video will walk you through the activity step-by-step, ensuring a fun and educational experience for you and your class!
