After briefing them on what happened and giving them a list of prime 'suspects', tell them that the only evidence left behind was a strange white powder and that it is up to them to solve the mystery. Provide each group with a worksheet that provides a place to document the results of evidence testing and room for an official statement on who the perpetrator is. For older, more advanced students, you may even decide to mix powders.
