Apple Cider Vinegar and Coins By Kelsey Sorenson
Hi class! Today we are going to experiment with apple cider vinegar and salt and see if it is able to clean coins. Our question is: Does apple cider clean pennies or silver coins (quarters, nickels and dimes) more effectively? Make a hypothesis: Do you think apple cider vinegar and salt will clean pennies or silver coins better?Introduction
You will need… Apple Cider Vinegar Salt Paper Towels Pennies, Quarters, Nickels, and Dimes Two bowls SpoonMaterials
Pour the apple cider vinegar into the first bowl.Step 1
Add a dash of salt too the bowl (not too much, about a teaspoon).Step 2
It looks like the coins look the same as before. Why do you think it didn’t work as well? Was your hypothesis right?What happened to the silver coins?
The apple cider vinegar cleaned the pennies better than the quarters, nickels, and dimes. This is because the pennies are made out of copper which is a different material than the mixture used to make the other coins!Conclusion
