This article describes a classic discrepant event. Using a candle made out of potato instead of wax students see it burning and are asked to record all their observations. Students discuss and compile all observations from the class. After this is completed, the teacher eats part of the candle. This construction of this candle is explained in the article. This is a good example of how what you see might not be what you expected to see.

This article describes a discrepant event with a potato candle. This leads to observations by students about the "candle" which are listed on an overhead. Then the teacher discusses the differences between observations and inferences. This discrepant event is a good one to use at the beginning of the school year.
