Apple cider vinegar and coins

  1. 1. Apple Cider Vinegar and Coins By Kelsey Sorenson
  2. 2.  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
  3. 3.  You will need… Apple Cider Vinegar Salt Paper Towels Pennies, Quarters, Nickels, and Dimes Two bowls SpoonMaterials
  4. 4. Pour the apple cider vinegar into the first bowl.Step 1
  5. 5. Add a dash of salt too the bowl (not too much, about a teaspoon).Step 2
  6. 6. Stir the mixtureStep 3
  7. 7. Place the pennies in the bowl. Let sit for about 20 seconds and then stir them around in the bowl.Step 4
  8. 8. Rinse the pennies off in the sink.Step 5
  9. 9. They definitely look cleaner than before! Some of them are super shiny. Some still have a little dirt on them but are cleaner than they were before.What happened to the pennies?
  10. 10. What do you think is going to happen?Now let’s take a look at the silvercoins!
  11. 11. Repeat the same process as the fist time. Mix together the vinegar and salt and then stir.Step 6
  12. 12. Place the quarters, nickels, and dimes in the mixture for about 20 seconds. Then stir.Step 7
  13. 13. Rinse them off in the sink.Step 8
  14. 14. 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?
  15. 15. 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
