Rotting Apples

We were inspired by the rotting apples post on the Science Sparks blog and decided to try our own experiment. Our results came out slightly different.

The experiment was to take four slices of apple, place them in four different conditions and then observe the decomposition. We placed our apples in salt water, vinegar, lemon juice and open air just as was done by Science Sparks.

The apple that was left in open air was covered in mold and definitely showed the most decomposition. We live in Germany and it is usually very humid here. Perhaps that is the reason our results were different.

Then we repeated the experiment a second week, but used different liquids as preservatives. The apples were placed in corn syrup, apple juice, oil and plain water. The apple in the apple juice was the only one to develop mold. The kids also noted the smell of fermentation. Although they thought it smelled like beer.
