Forensics-- what is it?
It's a search for evidence to confirm a belief. The belief comes first. That's the hypothesis. A hunch based on some previous knowledge or experience, but still it's a guess.
The process is key: As the facts become clear through the science of uncovering truth (observable facts), some answers are found, but more questions arise. Actually, the more facts are found, the more accurate the questions become. The process can be restated as a progressive refining and narrowing of the questions. When you ask the right question, you'll get the right answer!
Even the best forensic process can be wrong. TV shows like CSI would have us believe that forensics answer all the questions without doubt. But quite often, it's up to the court to decide. Even then, a certain amount of belief is called upon, and ultimately the verdict is delivered based upon belief: "Does the jury find the defendant guilty or not guilty?"
So here's my idea: Plan a history unit or even an entire course around the model stated above.
1. Start with "the crime."
2. Search for motives.
3. Pose a hypothesis.
4. Check and pursue factual evidence.
5. Evaluate the evidence, deciding where there is little doubt, and where there is much.
