Food Science: Apples

This month we looked into the science behind why apples turn brown and experimented with solutions to keep them from turning brown.
The teens divided into groups and each group tested different solutions to see what would prevent the apple from turning brown the best. Here is what one group looked at.

·         Water

·         Water and salt

·         Lemon juice

·         Vinegar

·         Put the apple core in a bowl too to serve as an control example           

        They also did this:

          Honey

·         Orange Juice

·         Carbonated water

·         Soda

·         Put the apple core in a bowl too to serve as an control example                                         

      The results of this experiment were super intriguing and the teens came up with a variation of their own which was hot water and salt.  This turned the apple brown faster and it made the apple taste a little like a pie apple. The other results showed that cold water and salt seemed to keep the apple from turning brown the best. They teens were really about this science and discovering that oxidization was what made apples turn brown. They also loved tasting the various apples and the solutions. Teens eat anything!
