Minute-by-minute · 80-minute block

💡 Big idea: A well-formed project question and methods plan are the foundation of independent scientific inquiry.

  1. 0-5 minWarm-up: share your draft project question from the prelab
  2. 5-20 minRefine your researchable question with teacher and peer input
  3. 20-40 minWrite your claim and outline your methods with variables and measurement units
  4. 40-55 minIdentify your independent variable, dependent variable, and control
  5. 55-70 minName one limitation and how it affects what your results can claim
  6. 70-80 minExit ticket: state your question, claim, and the one control you will include
Mr. Mendoza's 5-minute intro
  • Your capstone project starts here: a question you can actually investigate, and a plan to investigate it.
  • We'll use the same scientific method standard applied in every BI unit: claim, evidence, methods, limitation.
  • A good question is specific enough that you could answer it with the resources available in this class.
  • By the end of today, your project is defined and documented.
Do this, step by step
  1. 1State a clear, researchable question for your project.
  2. 2Write the claim you expect your project to support.
  3. 3Outline the methods you will use to gather evidence.
  4. 4Identify your key variables and how you will measure them.
  5. 5Note one limitation of your proposed approach.
You'll be able to
  • You wrote a testable claim with matching methods.
  • You named your variables and one limitation.
Know by the end
  • A testable claim specifies what you expect to find and in what direction.
  • Methods must include the independent variable, dependent variable, control, and measurement units.
  • Naming a limitation upfront shows scientific honesty and improves the overall design.

Your PLTW work today

Open this PLTW section today

Forensic chain-of-custody basics, independent project claim, final portfolio audit; no new curriculum after Dec 11. · Project question

Day 3 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.

Do this: Open Problem 8 in your myPLTW course shell and navigate to the current independent project activity, then define a testable claim and methods for your capstone project.

Complete

Add your project question, claim, and methods outline to the Problem 8 portfolio.

How far to get

The chain-of-custody table is done; project definition is the foundational Problem 8 milestone, so confirm your timing.

Upload as evidence

Project question and methods outline submitted as evidence.

All PLTW activities are completed inside the PLTW course environment — this page only gives direction. Submit producibles on Schoology.

Today's PLTW tracker

Check things off as you work, then submit. This tells Mr. Mendoza how you're doing so he can help the class. It does not replace turning in your producible on Schoology.

Forensic chain-of-custody basics, independent project claim, final portfolio audit; no new curriculum after Dec 11. · Project question

Open Problem 8 in your myPLTW course shell and navigate to the current independent project activity, then define a testable claim and methods for your capstone project.

The chain-of-custody table is done; project definition is the foundational Problem 8 milestone, so confirm your timing.

This is how Mr. Mendoza sees the class keeping pace with PLTW. Be honest, it only helps if it is accurate.

Safety / SOP
  • All biological materials must be handled at BSL-1 or as directed by the teacher for the specific organism.
  • Wear gloves, goggles, and lab coat whenever handling biological samples or chemical reagents.
  • Decontaminate all biological waste with 10 percent bleach before disposal; nothing biological goes in regular trash.
  • If PCR amplification is used, keep amplicons covered to avoid aerosol contamination of other samples.
  • Any human-sourced material (saliva, cheek cells) requires explicit teacher approval and must follow HIPAA-analogous data handling: no student names attached to samples.
  • Report any chemical or biological spill immediately; do not attempt to clean up alone.
  • Wash hands thoroughly with soap and water after any contact with biological or chemical materials.
