LESSON 1: MAKING OBSERVATIONS

SWBAT: Identify inquiry skills used to solve crimes.

WOD: Forensic Science- use of scientific knowledge and methods to answer legal questions

IA: Discover Activity Page 6- With a partner Discuss and record what do you know about solving crimes. Answer all questions in your notebook.

ML: What are the inquiry skills used to solve crimes?

Act: Independently- use your observation skills to locate the list of items in the classroom. Then answer the thought questions.

Sum: Exit Ticket- What do people who solve crimes base their predictions on?

Page 3: FORENSIC SCIENCE CHAPTER 1: CRIME SCENE INVESTIGATION Lesson 1: Making Observations Lesson 2: Teamwork at a Crime Scene Lesson 3: Forensic Science Methods

INQUIRY SKILLS USED TO SOLVE CRIMES

• Observing- using one or more of your senses to gather information

• Evidence- something that can be presented in court to make a point during a trial

• Inferring- offering a reasoned opinion based on observations and experience

• Predicting- stating an opinion about what will happen in the future

• Hypothesis- a possible explanation for a set of observations

Turn and talk

Has anyone ever borrowed anything from your locker or room without asking you? How did you know your things were disturbed? Discuss with a partner (3 min)

Page 4: FORENSIC SCIENCE CHAPTER 1: CRIME SCENE INVESTIGATION Lesson 1: Making Observations Lesson 2: Teamwork at a Crime Scene Lesson 3: Forensic Science Methods

MAKING INFERENCES

It is possible to make more then one inference from a set of observations.

Look at the picture in your text on page 8- what do you think is happening?

Write 2 inferences and make a prediction about what will happen next.

Now consider the following observations have been made:• An ambulance pulls away from the house• A police officer is talking with the person who lives in the house.• The person who lives there is performing CPR on a neighbor

How do these observations affect your inferences?

Inferences

Page 5: FORENSIC SCIENCE CHAPTER 1: CRIME SCENE INVESTIGATION Lesson 1: Making Observations Lesson 2: Teamwork at a Crime Scene Lesson 3: Forensic Science Methods

OBSERVATION VS. INFERENCES

Sometimes people confuse inferences and observations.

Scenario:

You have three fish in a bowl in a room. You hear a crash and run into the room. You see broken glass, water and one fish on the floor. Nearby, your cat is licking its paws. You think. “The cat knocked over the bowl and ate the other fish.”

Simple rule: People use their senses to make observations. They use their ability to reason to make inferences.

Page 6: FORENSIC SCIENCE CHAPTER 1: CRIME SCENE INVESTIGATION Lesson 1: Making Observations Lesson 2: Teamwork at a Crime Scene Lesson 3: Forensic Science Methods

ACTIVITY:

• You will each be given a list of items to locate within the room.

• You may look for items everywhere accept in the teachers desk drawers , in the closet or anywhere that is too high for Ms. Macchiarella to reach. HA! That’s everywhere- ;o)

• Do not tell others when you locate an item because it is a scavenger hunt/race.

• Do not share your lists because some are different and some are the same.

After you find your items answer the thought questions.

Where some items harder to find then others?

What made an item easy to find?

What made an item hard to find?

What inquiry skill did you use most during this activity?

Page 15: FORENSIC SCIENCE CHAPTER 1: CRIME SCENE INVESTIGATION Lesson 1: Making Observations Lesson 2: Teamwork at a Crime Scene Lesson 3: Forensic Science Methods

INTRO- STUDENT READ ALOUD- PG. 16

Why was Sherlock Holmes angry when he saw the trampled grass at the crime scene?

• Investigators must secure a crime scene as soon as possible to protect the evidence. This is the responsibility of the first-responding police officer.

• Transfer, loss, or contamination of evidence can occur if the area is left unsecured (Locard’s exchange principle).

• The first officer on the scene will begin keeping a security log of all those who visit the crime scene. The officer will collect pertinent information and request any additional

How do they secure the crime scene?

Page 16: FORENSIC SCIENCE CHAPTER 1: CRIME SCENE INVESTIGATION Lesson 1: Making Observations Lesson 2: Teamwork at a Crime Scene Lesson 3: Forensic Science Methods

SECURING THE SCENE

1. Establish Boundaries- bright yellow crime scene tape, ropes, traffic cones, parked police

cars, natural boundaries. Indoors – seal windows and doors

2. Control Entry- Map off a single path for people to use as they come in Keep a record log of all visitors

• Chain of Custody- written record of who had control of a piece of evidence from the time it was collected.• Contains names, dates, and places.

LESSON #5: RECORDING A CRIME SCENESWBAT: Identify and utilize methods investigators use to record a crime

scene by making a sketch.

WOD: record: an item or collection of data

IA: What are methods people use to record special events like birthdays, weddings, vacations, sporting events, ect.

ML: What are the ways investigators record a crime scene? Long range, medium range, point of view, and close-up photos.

Turn and Talk- with your partner look at the pictures on page 19 and discuss the photos.

Sketching a crime scene- convert feet to meters to keep scale

Activity: Complete pages 6 and 7 of the Student Handbook. Then Sketch a crime scene- Students will work to independently sketch a crime scene using methods discussed.

Sum: How is a sketch helpful, what are its limitations?

Page 27: FORENSIC SCIENCE CHAPTER 1: CRIME SCENE INVESTIGATION Lesson 1: Making Observations Lesson 2: Teamwork at a Crime Scene Lesson 3: Forensic Science Methods

HOW DO INVESTIGATORS RECORD A CRIME SCENE• Photographs-

• Video- sound is off, follows a path from outside the scene to the center, no team members are in the video.

• Sketches- done quickly and without much detail- investigators include the most important items.

• Scale Drawings- artist uses the sketches to make 2-d drawings or models of a scene.

• Written notes- must be organized and easy to read so that they can be used in trial.

• Dictated notes- speaks on a voice recorder while he/she does tasks at the scene.

Page 28: FORENSIC SCIENCE CHAPTER 1: CRIME SCENE INVESTIGATION Lesson 1: Making Observations Lesson 2: Teamwork at a Crime Scene Lesson 3: Forensic Science Methods

TURN AND TALK

Use your textbook page 18 and 19 to look at

• Long Range Photos

• Medium Range Photos

• Point of View Photos

• Close-up Photos

With your partner-

• Discuss the details that can be used to compare the different types of photos. What makes them different?

• Why would an investigator need to take different types of photos?

• On a scale of 1-10 how well did your partner understand the different photos?

Page 29: FORENSIC SCIENCE CHAPTER 1: CRIME SCENE INVESTIGATION Lesson 1: Making Observations Lesson 2: Teamwork at a Crime Scene Lesson 3: Forensic Science Methods

SKETCH VS SCALE DRAWING

Sketch-

• Done quickly

• Shows important items

• Shows actual measurements of items, walls, floors, etc

Scale Drawing-

• Artist puts detail

• Uses the sketch and actual measurements to draw or model to scale.

Convert feet to meters-

• The vault in a bank was robbed. The actual measurements are 12ft wide, 16 ft long, and 11 ft high. If 1 meter=3.28 feet how can we convert to meters?

12/3.28= ________ meters wide.

Sum: Share out- what evidence did you think was the most convincing?

Page 43: FORENSIC SCIENCE CHAPTER 1: CRIME SCENE INVESTIGATION Lesson 1: Making Observations Lesson 2: Teamwork at a Crime Scene Lesson 3: Forensic Science Methods

•Any object that can be used to prove that a fact is true. •It can be found at the crime scene or at another location related to the scene.

•Locard’s Principal states that- “Every contact leaves a trace. “ •Therefore, forensic scientists know that there is always a transfer of evidence at a crime scene no matter how careful criminals think they are.

Who is Locard? Edmond Locard, a french scientist who studied both medicine and law in the early 1900’s . Locard set up his own police laboratory in 1910 and soon became famous for his research into forensic science.

WHAT IS PHYSICAL EVIDENCE?

Give-one Get-oneBrainstorm silently a list of things that might be left behind by a criminal at a crime scene. Share your list with your partner and then add something from their list to yours. Be prepared to share
