Can a Criminal Get Away with Murder if He Cleans Up the Blood?
Many criminals try to clean up the blood left at a crime scene, but forensic scientists can still detect it using a luminol solution to find trace amounts. In this activity, your students perform the same techniques as real life forensic investigators to discover where simulated blood evidence may exist. Through this lab students’ will develop inference skills and reinforce the cross cutting concepts of cause and effect and pattern analysis. This activity allows students to explore NGSS Physical Science Disciplinary Core Idea PS1 (Matter and its Interactions).
This kit has been aligned with all published National Standards. Pre- and Post-laboratory assessments and vocabulary words all target specific Science and Engineering Practices and common core standards. The teacher guide also contains specific “Did You Know” concepts that link the real world with the scientific standards explored. A student copymaster is also included.
