Mystery Powder

 Starting in January 2013, all the third grade students were part of a “Mystery Powder” unit. The unit started with the shocking news of a “robbery" at the Temple up the road! Left at the scene of the “crime” was a white powder as the only evidence. All the students were engaged in observing the physical characteristics of three powders, Eek, Bug and Ace. Then students tested each powder with three liquids to observe the physical or chemical reactions that happened when liquids, Zip, Bop and Tap were added to each powder. Students were encouraged to write detailed descriptions of color, texture, hardness and smell. Finally when presented with the “evidence” from the crime, students had to identify which company was the culprit and provide evidence to support their suspicions.
