In a quest to identify who stole Roxy the science lab hamster, students will develop a hypothesis based on prior knowleddge and observations (NS.1.4.8). They will identify patterns and trends in data (NS.1.4.10) in order to narrow down the suspects and will generate conclusions based on evidence (NS.1.4.11).
