Examine an unlighted candle. Make a list of as many detailed observations of it as you can. It might help you to pretend you are describing it to a visitor who has never before seen or heard of a candle. Now, carefully light the candle and describe further as many additional observations as you can. Assume that such words as "wick," "candle," "flame," and "burning" will not be understood without detailed description and explanation. Number each observation for reference. List which observations were qualitative and which were quantitative. Quantitative data is something that can be measured such as; the candle is 3 inches tall and has a diameter of 2 inches. Qualitative data is sensory observations such as; odor, cold, hot, taste, texture, and appearance.
