We know apples turn brown when they’re cut, but why do they turn brown? Learn all about the process with a free oxidation experiment and worksheet.
The reason apples turn brown is because a chemical reaction happens. The inside of the apple is exposed to oxygen and an electron is lost, causing the meat to brown.
My kids think apple slices that turned brown are bad, but the truth is, they are perfectly fine to eat!
This informative experiment and worksheet will allow your child to explore oxidation and how to prevent it.
To do this experiment you’ll need small, labeled containers to hold a few materials. These materials are lemon juice, baking soda water, salt water, milk, and vinegar.
You’ll also need an apple and a knife or a slicer.
Help your child cut the apple and place a piece in each solution. Leave them for five minutes.
Remove the apples and place them on a plate or towel. Leave them for a few hours.
Invite your child to come back to investigate the results. Let them determine which solution stopped oxidation the best!
