Science Buddies: Project Ideas: Bitter to Sweet: Sugar Changes in Ripening Fruit

In this science fair project, use a refractometer to measure changes in sugar content in ripening fruit. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and questions, bibliography, list of materials and equipment, experimental procedure, suggestions on how to vary the experiment, plus a focus on the sort of careers this experiment might relate to.
