Lab/Activity Ideas
Activity One:
I have a crime scene out. Kids learn types of evidence/observation skills/scientific
method(p9) make a handout of p16-17, 65 Lee book scientific method
P25 Lee book classify/individualize make handout
I need some kind of chart for them to fill in
crime scene reconstruction of events/ types of searches, grid etc with planted
evidence…….teach exemplar vs evidence, individual vs class evidence, types of physical
evidence that has probative value vs non probative
add to first lesson http://www.feinc.net/cs-proc.htm
Activity Two: Court TV mini crime scenes??
http://school.cengage.com/forensicscience/home.html go to chapter 2, do interactive
activity for kids to get used to working their own crime scene
Each bench designs a crime scene using evidence. Other team solves it:
