DO NOW
Face your name tent towards the front of the room
Study the picture… • How many animals were here? What kind were they?• What were they doing?• Were they here at the same time?
On your note paper, use your best guess and write down what you think happened at this scene.
3 people will share.
How was that activity related to forensic science?

Welcome to 5th period forensic science!Pick up all materials from the “Do Now” boxes (in the cabinet)

Turn to your learning partner and give them a sincere
compliment.

5 minYou can only sign a paper ONCE
Prize for the person who fills in all boxes first
LEARNING OBJECTIVE
Write your own example of
deductive reasoning
ONE EXAMPLE
https://www.youtube.com/watch?v=RrzBQskzDo8
What observations does Sherlock make?
What conclusions does he draw?
Deductive Reasoning
Making inferences or drawing conclusions based on available evidence
– Observe a situation– Organize it into parts– Evaluate the parts– Draw appropriate conclusions
ANOTHER EXAMPLE
https://www.youtube.com/watch?v=H9PY_3E3h2c
Identify example(s) of deductive reasoning.
How is this different?
Deductive reasoning
When you use deductive reasoning, you don’t always come to a true or correct conclusion.
Your observations and assumptions must be sound and reasonable for you to reach true and correct conclusions.
Deductive Reasoning Example
• All men are mortal. observation • Mr. Cater is a man. related observation• Therefore, Mr. Cater is mortal. conclusion / inference
With your learning partner, create your own deductive reasoning example. You have 5 minutes.
3 groups will be called on at random to share.
Paper work• I need your paperwork
CRITICAL ANALYSIS REMINDER• Critical Analysis 1
– For Analysis 1 you will be reading a Sherlock Holmes story and answering questions about how deductive reasoning was used
– Due Sept 12th – B
– Due Sept 11th – A
– There is an entire Sherlock Holmes PDF on our website www.tinyurl.com/crockettcater.
Deductive Reasoning Article
• Read the article. (10 minutes)• Each time you reach a sub-heading, write a note or two
back and forth with your learning partner about the section you just read.
• Mention your feelings towards the article.
2 groups will be called on at random to stand up and read their written
conversations to the class.
SWITCH SEATS / PARTNERS
• Find the person who has the same color popsicle stick as you do.
• You can choose your new seat – you must sit next to your new partner.
EVIDENCE
Locard’s Exchange Principle
• “When a person comes into contact with an object or another person, a cross-transfer of physical evidence can occur.”
• the intensity, duration and nature of the materials in contact determine the extent of the transfer.
Brainstorm on large paper
• Using a marker and large paper, write down as many pieces or types of evidence as you can during the next 5 minutes.
Pick up popsicle sticks, place in chem closet
Gallery walk
• Place paper on the wall.• Gallery walk – read all papers.• Sticky notes – Place comment
on at least 3 others’ papers.
5 min – then take paper back to your seat.
Evidence
Anything that tends to prove or disprove something.
LEARNING OBJECTIVE
Classify evidence into appropriate
categories
On your chart paper
Classify each type of evidence on your paper as we go through the next few slides.
Testimonial evidence includes oral or written statements given to police as well as court testimony by people who witnessed an event.
Physical evidence refers to any material items that would be present at the crime scene, on the victims, or found in a suspect’s possession.
Trace evidence refers to physical evidence that is found in small but measurable amounts, such as strands of hair, fibers, or skin cells.

What will evidence collected at a scene do for the investigation?
• May prove that a crime has been committed• Establish key elements of a crime• Link a suspect with a crime scene or a victim• Establish the identity of a victim or suspect• Corroborate verbal witness testimony • Exonerate the innocent. • Give detectives leads to work with in the case
Types of Evidence
Types of Evidence
Direct: firsthand observations (eyewitness account, video camera, confessions)
Circumstantial: indirect evidence; implies a fact, but not directly prove it
Types of Evidence
• Physical: Impressions from fingerprints, footprints, shoe prints, tire impressions, tool marks, fibers, weapons, bullets, and shell casings
• Biological: body fluids, hair, plant parts and natural fibers
Types of EvidenceClass Evidence• Narrows identity to a group
of persons or things• Example: blood type
Individual Evidence• Narrows identity to a single
person or thing• Example: fingerprint, DNA
Crime Scene EvidenceCrime Scene Evidence
• Direct or circumstantial evidence?• Physical or biological evidence?• Class or individual evidence?
YOUR CHART PAPER
• Make sure your name / seat number and your partner’s name / seat number is on there.
• Fold them and drop them in to the box as you leave.
LATERAL THINKING
In the middle of the ocean is a yacht. Several corpses are floating in the water nearby.
LATERAL THINKING• Alternate Solution #1• A group of people were on an ocean voyage in a yacht.
One day, they decided to go swimming -- they put on their swimsuits and dove off the side. They discovered belatedly that they have forgotten to put a ladder down the side of the yacht and were unable to climb back in, so they drowned.
• Alternate Solution #2• The same situation, but they set out a ladder that was
just barely long enough. When they dove into the water, the boat, without their weight, rose slightly in the water, putting the ladder just out of reach.
LATERAL THINKING
A man is lying dead in a room. There is a large pile of gold and jewels on the floor, a chandelier attached to the ceiling, and a large open window.
LATERAL THINKING
Solution:The room is the ballroom of an ocean liner which sank some time ago. The man ran out of air while diving in the wreck.
LATERAL THINKING
A woman has incontrovertible proof in court that her husband was murdered by her sister. The judge declares, "This is the strangest case I've ever seen. Though it's a cut-and-dried case, this woman cannot be punished."
LATERAL THINKING
Solution:The sisters are Siamese twins.
