Students explore the viscoelastic properties of silly putty.
We’ve talked about deviance more broadly, but today we’re focusing on crime, specifically in the US. We’ll start with legal definitions of crime and use FBI data to get an idea of the amount and kinds of crime committed in the US. We’ll also use that date to paint a demographic picture of who gets arrested, and explain why that’s not necessarily a full look of who commits crime. We’ll also discuss society’s response to crime in the criminal justice system, and how that response has resulted in mass incarceration.
Law enforcement has relied on fingerprint analysis to identify suspects and solve crimes for more than 100 years. Investigators use fingerprints to link a perpetrator to a crime scene. Individual fingerprint identification records have also been used in sentencing, probation, and parole decisions. Officers often rely on chemical techniques, such as those above, to visualize the evidence. However, inadequate proficiency testing of investigators has led to inaccurate interpretations of the evidence. Recent wrongful convictions and scientific studies of forensic methods have increased scrutiny of the validity and reliability of several forms of forensic evidence, including fingerprints. A recent report prepared by the President’s Council of Advisors on Science and Technology (PCAST) makes strong recommendations for improving the scientific basis of forensic evidence used in the courtroom. For fingerprinting, the report emphasized the potential for automating fingerprint analysis, to potentially reduce bias in interpreting match results when fingerprints at a scene are smudged or otherwise unclear.
How It’s Done
Samples That May be Collected at a Crime Scene
A wide variety of physical evidence can be collected at a scene that is deemed valuable (“probative”) for collection and investigation:
-biological evidence (e.g., blood, body fluids, hair and other tissues)
-latent print evidence (e.g., fingerprints, palm prints, foot prints)
-footwear and tire track evidence
-trace evidence (e.g., fibers, soil, vegetation, glass fragments)
-digital evidence (e.g., cell phone records, Internet logs, email messages)
-tool and tool mark evidence
-drug evidence
-firearm evidence

-How a Crime Scene Investigation is Conducted
-How and Where Tests on the Evidence are Conducted
Crime Scene features fictional crime cases in a unique combination of interactive fiction and gaming.
Each week, Yoknapatawpha County detectives post evidence from the current case.
You are invited to participate in the investigation by reviewing the presented evidence and offering your theories and questions to the detectives and other web sleuths.
The following simulated crime scene is designed to test your observation and knowledge. Observe each image and respond only to the questions associated with each image.
What is criminal profiling?
Criminal profiling is an important part of a criminal psychology. This part of an article will partially answer questions about what criminal profiling is, what it is used for, what is aim of it, in which cases it is mostly used, what are it’s types and what kind of approaches it has.
In short, Criminal profiling (also known as offender profiling and specific profile analysis) is to create a psychological and not only psychological portrait, determine location of the offenders by gathering their personal attributes from crime scene behavior in order to assist in detection of them.
Criminal profiling is typically used when offender’s identity is unknown and with serious criminal offences such as murder, sexual assault. Profilers also work on crime series, where is considered, that the crime is committed by the same offender.

Students take their ideas from the classroom page to the community pavement when they participate in a service-learning project based on their multimedia presentations.
Students will really warm up to this lesson about global warming as they study multimedia materials and use a variety of comprehension strategies.
By looking at advertising and mass media critically, students begin to understand how the media oppresses certain groups, convinces people to purchase certain products, and influences culture.
By critically analyzing popular television programs, students develop an awareness of the messages that are portrayed through the media.
Students make predictions about the stories and analyze story elements, compare and contrast the different stories, distinguish between fact and opinion, and draw conclusions supported by evidence from their readings.
The power point will provide strategies and to add skills to our toolkits that can be used to help engage our students in the use of 21CC skills- one of the focuses this year is Critical Thinking. The deBono’s Thinking Hat strategy is a great way to help us think differently and critically. As well, teachers will find a Critical Thinking (Socratic/Scholarly Discussion) Rubric, 3 more various Critical Thinking rubrics, Critical Thinking Exit Slips, a deBonos thinking hat explanation, a deBonos Thinking Hats worksheet, a PMI (Plus-Minus-Interesting) document and activities associated with ctritical thinking.
A lesson to help students understand the importance of critical thinking, and gain experience in using critical thinking strategies.
Critical Thinking Cheat Sheet from Wabisabi Learning.
This great resource looks at the who, what, where, when, why and how of critical thinking.
« TC² est un organisme à but non lucratif... Notre objectif est d’aider les élèves à apprendre à penser et à penser pour apprendre. »Le site du Critical Thinking Consortium (TC²) propose d'excellentes ressources gratuites pour l'enseignement de la pensée critique, surtout en sciences humaines et en mathématiques.
These are example rubrics for measuring growth in CRITICAL THINKING. Rubrics are provided for K-5, 6-9 and 10-12.
