experimental design faults that occurred

- Connects the scientific concepts of the investigation (as mentioned in

introduction) to a specific global/societal real life application.

(This should not focus on the particular variables or scenario used in the

experiment – it should focus on the “because” portion of the hypothesis.)

Chemistry: Forensics is an inquiry-based laboratory course that emphasizes essential concepts with real world

applications and forensic science as the over-aching theme. Students will explore topics such as structure

of matter; molar relationships; gas laws; chemical reactions; qualitative analysis; acid/base reactions; and
