💡 Big idea: Weighing evidence means judging both what each stream tells you and how much to trust it, given its known limitations.
- 0:00Review the four evidence streams; class brainstorm: which do you trust most and why?
- 0:12Teacher notes: evidence reliability weighting criteria (controls, chain of custody, method)
- 0:25Students list all evidence items for each of the four streams from their unit work
- 0:40myPLTW: complete the open-investigation online planning task
- 1:00For each stream, identify the one variable or limitation that most weakens it
- 1:10Planning sheet complete; preview Wednesday evidence-board build
- • You have four streams of evidence from this case: what was found at the scene, what the lab tests showed, what we know about the suspect, and what the histology revealed. Today you organize them.
- • Not all evidence is equal. Physical evidence from a controlled lab test with documented controls is more reliable than witness testimony from a single source. We are going to rate each stream.
- • A strong report is not the one with the most evidence. It is the one that weighs the best evidence, addresses the conflicts, and states the conclusion clearly.
- • By the end of today you will have a planning sheet ready for Wednesday's evidence board. Think of today as your outline before the argument.
- 1Take notes on how to weight different evidence types by reliability.
- 2List the four evidence streams you must integrate in this case.
- 3Review what a strong investigative report includes and omits.
- 4Complete the PLTW open-investigation online planning task.
- 5Identify which variables and limitations weaken each evidence stream.
- • I can list the evidence streams a conclusion must integrate.
- • I can judge evidence reliability for synthesis.
- • The four evidence streams in this case are scene documentation, laboratory tests (biomolecules and toxicology), suspect information, and autopsy/histology findings.
- • Evidence reliability is higher when the collection method was controlled, the chain of custody is unbroken, and controls were used.
- • A strong investigative report states the conclusion first, then supports it with the strongest evidence and explicitly addresses contradicting findings.

Day 2 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Open Lesson 1.3 Open Investigation in myPLTW and complete the evidence-synthesis planning task for the report.
Mark the Lesson 1.3 planning task complete in myPLTW.
You read the Lesson 1.3 overview Monday. By the end of today the planning task and your four-stream evidence list should be done.
