Science Buddies: Project Ideas: Simple Device to Measure the Strength of Tea

In this science fair project, measure the strength of tea, using plastic cups, a photoresistor, and a multimeter. 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.
