SCIENCE EXPERIMENT: HOW TO CLEAN PENNIES
With a grown-up’s permission, fill some cups with a small amount of different
substances to see which ones get dirty pennies the cleanest.
Before you begin, take a guess at which substance you think would clean the
pennies the best. Make sure to find the dirtiest pennies!
Be sure to let the pennies soak in each substance for a little while, then wipe or
scrub the pennies with a paper towel. Finally, put them on paper towels to dry.
