Apples and Oxidation

Many of my first grade students thought that apples turned brown because they were dirty.  We learned that oxidation occurs when the flesh of the apple is exposed to oxygen.  Rust is also oxidation.  We tried to prevent oxidation using a variety of liquids.  We had a control apple that we didn’t submerge in a liquid.

We took this experiment through the scientific process.  First grade students completed their first lab reports.
