I use this introductory exercise at the beginning (the very first thing) of my one semester topics course in Bioinorganic Chemistry and as the first exercise in my Bioinorganic unit in my senior level Inorganic Course.  The exercise is a very simple one, but generates a lot of great discussion, requiring students to access knowledge from prior chemistry and biology courses, as well s common knowledge from sources external to their academic career.  Students are often surprised to see how much they know before a topic is covered.  

This collaboratively developed inorganic chemistry-based ethics case study has been designed for use with general science students (not necessarily chemistry or inorganic chemistry students).  It could be used as part of a research ethics training program for undergraduates or as a stand-alone research group meeting on ethics or class assignment on data integrity. In this particular case study two data points are suspected of being in error because of a student mistake in labeling samples.

This is a simple and quick demonstration of the process oftempering of a solid, and the dramatic
