This multi-day unit will have students using a variety of techniques to gather data and evidence from a given criminal investigation. A woman is found dead at the base of her staircase by a neighbor and evidence shows that she did not just fall down those stairs, but rather was pushed to her death. Students will have to use investigative skills to gather evidence, interview suspects, build a logical timeline that includes time of death, and analyze their data/evidence to correctly identify who committed this crime.
