RHMS Grade 7 scientists took on an exciting challenge today in the lab! Someone snuck into Ms. Quidayan's house and stole her cookies straight from her cookie jar. The only clue? A mysterious white powder left behind on her door handle!  Using their knowledge of chemical reactions, they tested and observed chemical properties of several white powders and compared this to the mystery powder to identify the culprit. Do you think they were successful in finding the culprit?
