We studied the effects of different types of soda on teeth using eggshells as a substitute for teeth given both have similar compositions.

Great work creating a clear and interesting experiment. I like how you compared several sodas and observed the eggshells over many days. Your pictures and timeline made it easy to see what changed and how the different drinks affected the shells. Excellent effort and strong investigation!
Great project!! I didn’t know how bad soda was for your teeth!!
What a powerful and eye-opening experiment! 🥚🥤 Using eggshells as a model for teeth was a very smart choice since they have similar compositions. That shows you were thinking carefully about how to safely test your question while still making it scientifically meaningful. Observing changes and comparing results between sodas is exactly how scientists investigate cause and effect.
Your project connects chemistry to everyday health in a clear and important way. Excellent work designing a thoughtful experiment. Keep exploring big questions like this!
