Cupid loves sweets, but his dentist is worried. We know sugar causes cavities, but there is a hidden chemical danger lurking in those sour candies that acts much faster.
In this colorful investigation, your students will become dental detectives to reveal which treats are safe and which are enamel enemies.
The "Acid" Test: Turn a candy tasting session into a rigorous chemistry lesson.
- The Mystery: Why do sour sweets make your mouth pucker? And is that "sour" taste actually an acid burning your teeth?
- The Experiment: Students will test the pH of common Valentine's treats. No pH meter? No problem we include a guide to making your own indicator from red cabbage!
- The Science: It’s a battle of chemistry! Students will use the pH scale to visualize how acidic different foods are and understand exactly how low pH erodes tooth enamel.
Curriculum Concepts You’ll Cover Brush up on chemistry basics with a practical twist:
- KS3 Acids and Alkalis: The pH scale, indicators, and neutralization.
- KS4 Chemical Analysis: Hydrogen ion concentration and using indicators.
- Scientific Inquiry: Testing hypotheses and analyzing qualitative data.
