Green Pennies


This activity is a great introduction to basic chemical reactions, experiments, and the scientific process. We love this activity because there is so much to explore and discuss, and additional experiments to keep the fun going!

Set up

Your ‘science lab’ will be any flat space that won’t mind a little vinegar being spilled on it — kitchen tables and counters work great! The experiment then needs to be left out for five days.






30 minutes of set-up; five days of observation

Key Concepts

Chemical reaction, oxidation reaction, acids

If you think this looks fun, wait ‘til you try these!
