2. Warm Up
Objective: Scientists will describe deductive and inductive reasoning by using their reasoning skills to solve puzzles.
What is the topic? Deductive and inductive reasoning
What will you be doing? Solve puzzles
Why is this important? Reasoning skills are used to solve crimes, future career choice
How will you know if you have done well? Able to describe deductive and inductive reasoning, able to solve puzzles

3. Why is this important?
Forensic scientists use known reasoning and suspicion to help solve and process crimes.
The first step to crime scene analysis will always be OBSERVATION.
All analysis of the scene will build off of the observations.
Observations lead to questions. Questions lead to problems. Problems get solved.
Question: Does the evidence make the crime scene make sense?

4. Evidence
Physical Evidence: Any and all objects that can establish that a crime has been committed or can create a link between the crime and the suspect.
Indirect evidence: does not prove a fact but establishes suspicion or an educated guess
Circumstantial Evidence: does not prove but will make it more probable than suspicion (more likely)

5. What is Deductive Reasoning?
Takes a general rule and uses it to make a more specific example.
Draws conclusions from previous known facts and definitions.
For Example
All dogs have a tail.
Buddy is a dog.
Therefore Buddy has a tail.

6. What can you infer based on these observations?
Inference
a conclusion or opinion that is formed because of known facts or evidence
Example:
A body is found in an alley. He is a very large man. He was stabbed 17 times. There is no blood in the alley.
What can you infer based on these observations?

7. Inductive Reasoning Uses specific examples to make a general “rule”
Finding patterns or stereotypes.
Example: Yesterday’s dinner was delicious. Sunday’s dinner was delicious. Therefore, all dinners are delicious.

8. Solve the mystery Be sure to write your clues down and how you came to your conclusion.

9. Mystery Boxes What do you think is in each of the boxes?
What clues helped you to decide that?
What clues would have helped you solve the mystery?

10. Puzzles
Read each clue individually. Try to solve it on your own first.
Pair up with someone. Do you agree? Disagree? Why?
Discuss in your group/class.
