On Wednesday, we continued traveling through second grade to explore science. We went to Mrs. Caporello's room, where she showed us how to clean the dull coating (also known as copper oxide) off of pennies using salt and vinegar!
One friend even tried out this experiment at home! This site has a lot of great ideas to extend this experiment even further: Science Bob. Thanks for sharing a new experiment (and your pennies) with us, Mrs. Caporello!
