Week overview - Innovation, Inc.: designing and testing a biomedical device

Dec 14–18

Apply the engineering design process to model and test a biomedical device, using constraints, criteria, and a to drive iteration.

Week arc
  1. 1Define constraint, criterion, and prototype, then state one of each for your device.
  2. 2Sketch a CAD-style concept of your device, such as a or vessel model.
  3. 3Build a simple physical prototype from the available materials.
  4. 4Write a stating what you will measure and what result counts as success.
  5. 5Run your test, record the data, and note where the prototype met or missed its criteria.
  6. 6Describe one iteration you would make and how it should improve performance.
By week end
  • You will be able to state constraints and criteria for a biomedical device.
  • You will be able to build and test a prototype against a written .
  • You will be able to justify a design iteration from your test data.

Get oriented

Quick intro to the week

  • Hook: a that saves a life started as a rough prototype that someone tested and improved.
  • Today's goal: move through the design process from concept to a tested, improvable prototype.
  • Monday bioethics debate ties in: how much testing is enough before a new device is used on patients?
  • Reminder: your graded prototype, , and iteration notes are submitted on the class site.
Do the work

Your PLTW coursework this week

Do this: Advance your PLTW PBS innovation benchmark by completing the device prototype, , and iteration notes in the online course shell.

Know when done
  • Constraints and criteria define what a successful device must do and stay within.
  • Iteration uses test data to improve a prototype step by step.
  • A states the measurement and the result that counts as success.
Be able to do
  • Build and test a prototype against a written .
  • Justify a design iteration using recorded data.

📋 PLTW evidence due: the completed device prototype, , and iteration notes in the course shell.

All PLTW activities are completed inside the PLTW course environment: this page only gives direction.

What to do when absent

If YOU are absent

Most days, this class is your PLTW coursework: and PLTW is online and individual. So being out usually just means doing exactly what we did in class, from home.

Open Clever, then myPLTW

How to get there: open Clever and sign in with your Microsoft (district) account. Both myPLTW and Schoology are in Clever. Do the activity in myPLTW. Then use the one route named under Submit here on the day page. Schoology only shows your report-card grade later.

Was today a lab or a group activity?

You can't do those from home: do this instead: Teacher-posted data/model packet, same objective. Supplemental: Khan: experimental design/statistics; NIH biomedical engineering career pages.

If MR. MENDOZA is absent

Class still runs. A substitute will post today's plan: complete the online activity above; it's built to be self-guided. Need the concept taught without a teacher? Use this authoritative explainer:
