Can't Judge a Powder
Welcome to Can't Judge a Powder! In this event, students will test and characterize one pure substance and then, based only on data they collect, answer a series of questions about that substance. Students will not be asked to identify the substance. Emphasis of this event is on the quality of data collected, answering questions about the substance and providing data to support their answers.
