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.

Eclipse

On September 27th, there will be a rare event in the night sky- a supermoon lunar eclipse.  It has only occurred five times since 1900.  The last time we saw this event was in 1982 and it won’t happen again until 2033.
