Our A-peeling Project

Water in Apples
(AIMS Newsletter, July-Aug. 1989)
An Experiment in Evaporation

Students will work in groups. 
Each group will use a different variety of apple in season.
Varieties: 
Fugi, Gala, Granny Smith, Red & Golden Delicious.
Step 1:
The first  apple will be left whole or as is; one will have the skin pared off of it, but not cut up; and the third apple will have the skin left on, but cut up into small chunks. 
Step 2:
Each group will record the initial weight of the apples using a mass balance.  Each will use a plastic plate which will be weighed and deducted from measurements.  Recoding their findings.
Step 3:
Each group will weigh their apples daily for one week recording their results.

 Step 4:
Groups will make computation on daily weight loss and total weight loss.  This data will be entered into an Excel spreadsheet and graphed.
