Agenda Guided Walkthrough – History and Vocab Visual Walkthrough – Pre-lab for Locard (HW) Scrimmage/Practice – Deductive Reasoning Lab

Guide to Taking Notes!! If the text is in BOLD or underline then that needs to be written down in the notebook You are free to translate anything else down in your notebook as well.

Who was Edmond Locard? Director of the very first crime lab His techniques were able to determine where soldiers died during World War I by examining their stains “Physical evidence cannot be wrong, it cannot perjure itself, it cannot be wholly absent. Only human failure to find it, study and understand it, can diminish its value”

Vocab Locard’s Exchange Principle – when two items come into contact, there will always be an exchange. This is the basis of trace evidence Trace Evidence – the material found at a crime scene or accident scene in small but measurable amounts

Which ever choice you make. You must document ALL locations where you go throughout the day with that shirt on At the end of the day, place the shirt in a bag or Ziploc and bring it back into school tomorrow along with your sheet of documented locations

Deductive Reasoning Lab You guys will work on this deductive reasoning activity in groups. Each group of four will only receive one packet Remember to delegate roles so everyone is involved Turn in data tables 1 & 2, and the four post-lab questions before you leave today to receive credit for the activity Make sure all names are on the document
