What Is It Like to Analyze a Crime Scene?
This lab addresses several different approaches for conducting a crime scene investigation. Its scenario-based activity allows students to become detectives and determine ""whodunit"" while using Ward’s® completely safe Simulated Blood. Students attempt to solve a crime by matching the blood type of samples found at the ""scene"" with those of several suspects. After extracting samples from crime scene fabric stained with Ward’s® Simulated Blood, students can analyze them under the microscope, and perform blood type analysis to match the blood type with one of four suspects to help identify the culprit. In completing this lab activity, students employ NGSS Life Science Disciplinary Core Ideas LS1 (Structures and Processes) and LS3 (Heredity).
This kit has been aligned with all published National Standards. Pre- and Post-laboratory assessments and vocabulary words all target specific ""Did You Know"" concepts that link the real world with the scientific standards explored.
