The Science of Penny Cleaning

The Sprouts class recently completed a fun, mini, science project using pennies, table salt and vinegar.

We gave each child an old, discolored penny which they placed in a small container. We poured vinegar into small baby food jars and added eye droppers.

The children squeezed a few drops of the vinegar onto the pennies and then sprinkled some salt on top. They used a q-tip to rub the pennies. The children loved seeing how bright and shiny the pennies became!
