Are You Cavity Prone? Demo BioKit (with Prepaid Coupon)

Students determine their susceptibility to dental cavities based on the rate at which bacteria from their mouths produce acid in a carbohydrate medium. As the pH of the medium falls, an indicator changes color. The rate at which the medium changes color is correlated with the student's susceptibility to cavities. This activity requires 4 days from setup to completion. Contains materials for 10 tests for individual project/teacher demonstration. Prepaid coupon for cultures included.
