Turn a penny green

This post from Buggy and Buddy includes a free printable graph to record scientific observations. Turning a copper penny green is a simple yet rewarding experiment that is great for any kid older than age 3. Kids can observe the pennies over several days and track the color changes.

Science lesson: The acid in the vinegar helps oxygen in the air react more quickly with the copper metal. The green color is a compound called malachite.
