Variables

The independent variables are the types of plastic wraps that are being tested. The dependent variables are the measurement of evaporation (in ml) and the amount of oxidation (on a visual scale of 1 to 10). The constants are the temperatures of the liquids being tested in the evaporation section and the apple slices in the oxidation section. The control is measuring the oxidation of the apple and/or the evaporation of the liquids without the wraps in the temperature of a refridgerator.
