The Science of Penny Cleaning

October 4, 2016

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!
